Alligators living environment

Alligators live in freshwater, like habitat in lakes, swamps or hills of beach grass, basil mountain covered with damp areas. It has a superb ability to dig Punch, head, tail and sharp claws are its toe holes Punch tool. As the saying goes "Jiaotusanku" and alligator caves also more than three caves. It's often a few cave entrance, and some beaches on the shore reed, bamboo clusters of office, some in the pond bottom, with entrances on the ground, vent, but also to adapt to a variety of water level of the side of the hole. Winding caves, criss-cross, like an underground maze. Perhaps it is this underground maze to help them through the cold of the glacial maximum and the cold winter, but also help them escape predators and survive. To fish, frogs, snails and mussels, etc., as food. But sometimes attack poultry and crushed crops, plus it looks ugly, has long been considered to be harmful animals are killed, so scarce.

AlligatorUntil early June. Alligator mating in the water, fertilization. To early July or so, the female crocodile began weeds, litter and soil in a suitable place for building a circular nest eggs to use. July and August to lay eggs, litter can lay between 10 to 30. Eggs are white, slightly larger than the eggs. Eggs in the grass, weeds on the cover, the mother alligator will guard the side, this time is the hottest of the summer season, and soon, some nest material and the thick grass in the hot sunlight rot fermentation, and emit heat, crocodile eggs is to use this energy to heat and sunlight to hatch. In the incubation period, the mother often came to the nest next to the alligator guarding, incubation period is about 60 days, about two months time, the mother crocodile alligator in the nest to hear the calls of Aberdeen, will immediately clawed cover crocodile in Aberdeen Mulching above the body, helping Aberdeen alligator climbed out of the nest and lead them to the pool inside. Aberdeen crocodile surface with orange stripes, color is very bright, into a crocodile with the body color are quite different. Young crocodiles hatched in September. With hibernation habits. Alligator is a species unique to China, under difficult conditions in captivity breeding. In the kind of good environment and well-kept condition, Alligator in 1980 under China's annual output of the first baby crocodiles, a breeding success in captivity under the conditions precedent. Currently, the crocodile to live a quiet and comfortable in this environment, reproduce, their populations growing.

Worshipped and feared by the ancient Egyptians

  Worshipped and feared by the ancient Egyptians, the Nile crocodile is reportedly making a comeback. Amira El-Noshokaty sifts fact from fiction

“When I was a young boy, I would climb up the tallest tree on the Nile’s bank and from my perch, I could see the crocodile bury her eggs deep down in the sand. Later, I would watch her lead her young slowly into the waters of the Nile.” As we sat in his home in what was once the Nubian heartland, only a few kilometres from the Abu Simbel temple complex, hagg Abdou Mohamed spins a tale of the famous Nile crocodile. “My father told me that the crocodiles who swam up north were pure crocodiles, while those that swam south were a bad breed, called waren [mixed breed crocodiles],” Mohamed recalls.   The days Mohamed brings to life were not so long ago, but then man and crocodile lived in an uneasy harmony. The fishermen of Nubia would hunt crocodiles and stuff them with straw, hanging them over their doorsteps as talismans to protect against the evil eye. The crocodile’s mouth was left open, but the body was draped with colourful beads, explains Mohamed, who is a village elder.
For the people of ancient Egypt, the olom, as the Nile crocodile is known in the Nubian dialect, was much more than a good luck charm. In the time of the Pharaohs he was worshipped as the god Sobek, in whose honour the temple of Komombo was erected in Upper Egypt. The crocodile was also the master of Lake Qarun, in the oasis of Fayoum, which during the Middle Kingdom was known as the city of the crocodile — or “Crocodilopolis.”
“Crocodiles are depicted on Old Kingdom tombs in Saqqara,” Khaled El-Enani, professor of Egyptology at Helwan University told Al-Ahram Weekly. “They were worshipped as protection against the harm they could do.” In ancient times, the crocodile reigned over the Nile waters, and, according to El-Enani, they were known to attack fishermen’s boats, eat livestock and even hunt the hippopotamus. “We have records of holy songs sung by the fishermen of ancient Egypt to protect them while crossing the Nile. They also used magic spells to deter the crocodile from eating them.” It is not surprising then that the crocodile was also the symbol of danger. Seth, the god of wind and storms, was sometimes depicted as a crocodile.
Since ancient times, Egyptians living by the waters of the Nile have both feared and respected the crocodile. And though they worshipped it, they also sought to tame it. El- Enani notes that Herodotus recorded Egyptians keeping crocodiles as pets in the fifth century bc. “They would adorn them with gold bracelets and earrings and when they died, they had them mummified,” he added.
Today, the Nile crocodile, or crocodylus niloticus, is on the verge of extinction. No longer does it command the Nile waters. Instead, the crocodile has become the prize of ever-more stylised hunts. In the 1950s, professional hunters from around the world were given permission to come to Egypt and hunt crocodiles — a lucrative business considering the high price fetched by crocodile skins. By the 1960s what remained of the crocodile population was dammed off in the newly created Lake Nasser by the building of the Aswan High Dam. The lake was a secluded habitat and the crocodile population has managed to make a small comeback, aided in large part by the naming of the area as an environmental protectorate.
Prior to the prohibition of crocodile hunting in Egypt, there were no local professional hunters. The hunting procedure is, therefore, unlike the Sudanese tradition, as it does not involve any personal contact with the crocodile. In Egypt, crocodiles are shot, using a special technique to ensure that the bullet can pass through the thick skin.
The entrance of environmentalists into the long-running saga of the Nile crocodile is a peculiar twist for locals around Lake Nasser. Reda Fahmi has worked as a fisherman at the Abu Simbel marina for the past 22 years. “Fifteen years ago, smaller crocodiles would get caught in our fishing nets. We used to hunt them until the environment people told us to stop.” Environmental laws prevent all forms of crocodile hunting, but it is not the laws that have changed fishermen’s attitudes. According to locals, the crocodile has grown both in size and in strength. Fishermen claim that their nets are no longer strong enough to contain a crocodile caught in it. “Fifteen days ago, we were fishing and we ran into a crocodile that was seven feet long and two feet wide,” recounts Fahmi. He is not impressed with efforts to save the crocodylus niloticus, noting that they have a voracious appetite. Crocodiles are a threat to the fishing industry, he says.
Tall tales abound, but most locals agree that the crocodiles are multiplying and getting bigger. Ramadan Hussien, a fishermen at Lake Nasser since the early 1970s, told the Weekly that for most of his life, the crocodiles he saw were relatively small in size — less than five feet in length. A couple of months ago, however, he says he spotted one that was at least 15 feet long. Mourad Zulficar, an irrigation engineer responsible for monitoring the irrigation systems along Lake Nasser, recounts seeing “thousands of crocodiles lying lazily in the sun and burying themselves in the sand.” So rampant is the fear among fishermen that the old Lord of the Nile has returned to reclaim his legacy that they have begun once again to invoke higher powers to protect them against crocodiles.
There are no comprehensive statistics on the crocodile community in Egypt. In 1996 the Egyptian Environmental Affairs Agency (EEAA) formed a committee to look into complaints by the local community that not only were the crocodiles threatening their lives, but they were also responsible for damaging 100 metres of fishing nets per fishing round. The committee did find that the crocodile community was growing, but as to endangering local lives and wreaking havoc on the fishing industry, Moustafa Fouda, director of the Natural Conservation Sector at the EEAA dismissed them as “exaggerations and not based on facts.” Fouda told the Weekly that in the past 10 years, “there have been no records of any deaths as a direct result of a crocodile attack, except for one instance — and that does not make a very strong case against the Nile crocodile.”
He acquiesced, however, that until now, there has been no valid scientific research on this subject. To research the topic adequately, notes Fouda, his team would need all manner of high-tech devices and specialists, not to mention funding, which is not available. “We have asked for experts from different international environmental organisations ,but it was in vain. Those who came were not much help.”
But local fishermen have a different, more gruesome story to tell. Two years ago, a crocodile is said to have eaten a 16- year-old shepherdess east of Lake Hamido as she tried to defend her sheep. “And she was not the only one,” one local told me before recounting the story of a man who was eaten by a crocodile when he went down to the water to do his ablutions before prayer. Another fisherman was allegedly killed by a crocodile when his boat got stuck and he was in the water trying to move it.
These fishermen are not sympathetic with conservation efforts. “I just want to know, what’s the use of preserving an animal that has threatened mankind for so long?” growls local fisherman Reda Fahmi. But Helmi Beshai, professor of science at Cairo University, begs to differ. The crocodylus niloticus, he says, has an invaluable place in the delicate ecosystem of Lake Nasser. The crocodiles feed on catfish and crabs, which in turn feed on bolty fish in the lake. They also consume dead animals, which helps keep the water from getting polluted. Crocodile waste is also known to be a source of minerals, which enriches the nutrition base for fish in the lake.
Beshai did note, however, that only small, young crocodiles can subsist on insects. Once a crocodile has exceeded four feet in length, it will divert its attention to other vertebrates, including humans. But Beshai pointed out that people are not mindful of crocodiles’ breeding season. “Even though crocodiles will attack anyone who comes near their eggs and young, hunters continue to go after them during the time when they lay their eggs, which is from December to January.”
But money is a strong incentive. The meat is considered a delicacy in some parts and crocodile fat is used as a curative for rheumatic diseases. Crocodile leather, of course, remains the most expensive in the industry. Beshai argues, however, that setting up a hunting season would allow hunters to get what they need without disturbing the animals during a crucial life stage. “What about crocodile farms?” he asked.
A couple of months ago, the local press ran a story detailing plans by the Association for Wildlife and Tourism to set up a crocodile farm in an area of 500 feddans on the western side of Lake Nasser. But the reports were rejected by the EEAA. “No hunting or trading of the Nile crocodile, or any of its organs, is allowed in Egypt,” insists professor Sami El-Filali, under-secretary of state for soils, water and the environment at the Ministry of Agriculture and head of the Convention of Trade of Endangered Species (CITES) Authority in Egypt. The convention, which dates back to 1978, includes Nile crocodiles on its list of endangered species.
“Last year, we managed to arrest a teacher at Cairo Airport who was travelling to Jordan with some 60 small Nile crocodiles hidden in his luggage,” El-Filali told the Weekly proudly. “The crocodiles were handed over to the Giza Zoo and the traveller was sent to prison.”
Staring at me from behind big glass tanks half filled with water, 40 young crocodiles sat helplessly among other goods at the Friday market located behind the Sayyeda Aisha Mosque. Here everything is on sale — including the nation’s “protected” crocodiles. There are two merchants who specialise in the crocodile business, but both refused to speak to the me, saying that the press had already spoken ill of their trade well enough.
Since Nile crocodiles can no longer swim north past the Aswan Dam, it is clear that there is a dynamic trade smuggling them from their natural habitat in Lake Nasser. Hunting continues as well, despite tough regulations. In fact, locals told the Weekly that safari trips come all the way from Cairo specifically to hunt crocodiles in the months of December and January.
In ancient times, it was a battle for survival. Today, the battlefield is more complex. Is preserving the Nile crocodile as important, if not more so, than protecting those whose livelihood is the lake in which these animals live? It is a question for which there seems to be no answer — yet.

Steve Irwin -- The Crocodile Hunter


  Steve Irwin -- The Crocodile Hunter
Everyone knew who he was, and everyone is as equally shocked to know that the Crocodile Hunter is now dead after becoming the victim of a stingray's zap to his heart during a filming session over the weekend. And yeah, the photo above is from that time when Steve Irwin decided to introduce his baby son to a crocodile.
Having seen the grief expressed by the Australian Prime Minister and the rumors that a state funeral is being planned I was curious to see how the editorial cartoonists down-under are covering this event. Here's what I found:

Nile crocodiles are the largest in Africa

  In this image, a large crocodile is seen leaping clear of the ground in an attempt to snatch a chicken offered to it by a resident, in a pose which brings to mind a cat jumping for a toy.
The residents of Bazoule, a community outside Burkina Faso's capital Ouagodougou, began to hold the reptiles sacred around 600 years ago and offer them chickens as a sacrifice.
The tradition has continued to this day and visitors regularly go to the village to watch the ritual.
The deadly reptiles and villagers appear to live happily side-by-side with children apparently happy to play and do chores just yards from them.
Photographer Oliver Born, who captured the images, said: "It shows that crocodiles are not just ferocious and dangerous animals and that they deserve to be protected. Crocodiles are today completely integrated in the life of the population.
"It's not rare to see some children playing just metres away from them - it is quite a magical place."
The practice started in the 14th century when a local chief called Koud Naba ruled the area. During this period the inhabitants started believing the Nile crocodiles brought the seasonal rains, the absence of which can cause drought and starvation across the Sahel.
Now there are more than 100 of the creatures, which might not bring in the rains but certainly bring in the tourists.
Nile crocodiles are the largest in Africa. They can grow to almost 20 feet in length.

Many millions of years ago, the world was inhabited by a huge diversity of great reptiles

  
Big Croc - Maramba Lodge by hannes.steyn on flickr.com
  Many millions of years ago, the world was inhabited by a huge diversity of great reptiles. There were huge meat eaters, smaller, and probably nervous herbivores, and even smaller insect eaters. Some lived entirely on land, some were partially aquatic. They occupied the broad range of ecological niches we mammals do today. This sounds like a description of the dinosaurs, but in fact, it also applies to the crocodiles. Dr. Hans Larsson, a paleontologist and Canada Research Chair in Macroevolution at the Redpath Museum at McGill University, is part of a team that has just identified five species of crocodilians that lived about 100 million years ago, and are very different from modern crocs. Some had long legs and galloping stride, some were probably at least partial herbivores, and they were well adapted for living on land, and some were even more fearsome predators than modern crocodiles.

If you thought the legend of the horse whisperer was impressive

  If you thought the legend of the horse whisperer was impressive, here’s An animal tale with even more bite.

  Rather than trying to tame wild stallions, fearless Costa Rican fisherman Chito prefers a playful wrestle in the water with his best pal Pocho – a deadly 17-foot crocodile.
The 52-year-old daredevil draws gasps of amazement from onlookers by wading chest-deep into the water, then whistling for his 980-pound buddy – and giving him an affectionate hug.

  Chito made friends with the croc after finding him with a gunshot wound on the banks of the Central American state’s Parismina river 20 years ago. He had been shot in the left eye by a cattle farmer and was close to death.
Chito asked several friends to help load the massive reptile into his boat. He says, “When I found Pocho in the river he was dying, so I brought him into my house. He was very skinny weighing only around 150 pounds. I gave him chicken, fish and medicine for six months to help him recover.
I stayed by Pocho’s side while he was ill, sleeping next to him at night. I just wanted him to feel that somebody loved him, and that not all humans are bad. It meant a lot of sacrifice. I had to be there every day. I love all animals – especially ones that have suffered.”
It took years before Chito felt that Pocho had bonded with him enough to get closer to the animal.

  He says, “After a decade I started to work with him. At first it was slow. I played with him a bit, slowly doing more. Then I found out that when I called his name he would come over to me.”
At one point during his recovery, Chito left the croc in a lake near his house but as he turned to walk away, to his amazement Pocho got out of the water and began to follow him home.
Chito recalls, “That convinced me the crocodile could be tame.”
But when he first fearlessly waded into the water with the giant reptile his family was so horrified they couldn’t bear to watch. So instead, he would splash around with Pocho when his family was asleep.
Four years ago Chito showed some of his tricks to friends, including getting the animal to close his eyes on command, and they convinced him to go public with a show.

  Now he swims and plays with Pocho as well as feeding him at the lake near his home in the lowland tropical town of Sarapiqui.

  The odd couple have now become a major tourist attraction, with several tour operators. Visitors are t Taken on touring cruises to see the pair.

Hum… With hungry crocodiles in the lake, do you think the animal will still want to go drink the water?
It depends just how thirsty it is I guess…
Funny animal!
Geez, I really wonder what it this funny animal. Do you think it really exists, or is it just a fake picture? If it really does exists though, I really would not like to see one in front of me, except maybe in a zoo.It looks like a hybrid between a crocodile and another animal…

Archaeologists exploring crocodiles history

  Researchers describe the discovery in the journal Palaeontology. The findings help scientists better understand the diversity of animals that occupied the oldest known rainforest ecosystem, which had higher temperatures than today, and could be useful for understanding the impacts of a warmer climate in the future.
The 60-million-year-old freshwater relative to modern crocodiles is the first known land animal from the Paleocene New World tropics specialized for eating fish, meaning it competed with Titanoboa for food. But the giant snake could have consumed its competition, too, researchers say.

“The younger individuals were definitely not safe from Titanoboa, but the biggest of these species would have been a bit much for the 42-foot snake to handle,” says lead author Alex Hastings, a graduate student in geological sciences at the University of Florida.
The new species is a dyrosaurid, commonly believed to be primarily ocean-dwelling, coastal reptiles. The new adult specimens challenge previous theories the animals only would have entered freshwater environments as babies before returning to sea.
Fossils of a partial skeleton of the species, Acherontisuchus guajiraensis, show dyrosaurids were key players in northeastern Colombia and that diversity within the family evolved with environmental changes, such as an asteroid impact or the appearance of competitors from other groups, says Christopher Brochu, an associate professor of vertebrate paleontology at the University of Iowa, who was not involved in the study.
“We’re facing some serious ecological changes now,” Brochu says. “A lot of them have to do with climate and if we want to understand how living things are going to respond to changes in climate, we need to understand how they responded in the past.
“This really is a wonderful group for that because they managed to survive some catastrophes, but they seemed not to survive others and their diversity does seem to change along with these ecological signals.”
The species is the second ancient crocodyliform found in the Cerrejon mine of northern Colombia, one of the world’s largest open-pit coal mines. The excavations were led by study co-authors Jonathan Bloch, associate curator of vertebrate paleontology at the Florida Museum of Natural History, and paleobotanist Carlos Jaramillo of the Smithsonian Tropical Research Institute.
“This one is related to a group that typically had these long snouts,” Hastings says. “It would have had a relatively similar diet to the other (coastal) species, but surprisingly it lived in a more freshwater environment.”
The genus is named for the river Acheron from Greek mythology, “the river of woe,” since the animal lived in a wide river that emptied into the Caribbean. Unlike the first crocodile relative found in the area, which had a more generalized diet, the snout of the new species was long, narrow and full of pointed teeth, showing a specialization for hunting the lungfish and relatives of bonefish that inhabited the water.
“The general common wisdom was that ancestrally all crocodyliforms looked like a modern alligator, that all of these strange forms descended from a more generalized ancestor, but these guys are showing that sometimes one kind of specialized animal evolved from a very different specialized animal, not a generalized one,” Brochu says. “It’s really showing us a level of complexity to the history that 10 years ago was not anticipated.”
During the Paleocene in South America, the environment was dominated by reptiles, including giant snakes, turtles, and crocodiles. The dyrosaurid family originated in Africa about 75 million years ago, toward the end of the age of dinosaurs, and arrived in South America by swimming across the Atlantic Ocean.
“The same thing that snuffed out the dinosaurs killed off most of the crocodiles alive at the time,” Hastings says. “The dyrosaurids are one of the few groups to survive the extinction and later become more successful.”

World’s Biggest Crocodile Should Be Set Free

  
croc
If you thought those hideous rubber shoes were the scariest Crocs on the scene, think again. Philippine hunters just captured a gigantic crocodile this weekend in a saltwater marsh on the southern island of Mindinao. Stretching an alarming 21 feet long and weighing about 2,370 pounds, it's possible this croc, which they've named Lolong, is the biggest saltwater croc ever to be captured. It took over 100 people to wrassle Lolong into captivity after 30 or so men spent three weeks tracking the aquatic beast. After a 12-year-old girl's head was bitten off two years ago, and after a local man went missing recently, and after someone said they saw a behemoth croc take down a water buffalo (yikes) ... the hunt was on for the epic reptile.   But now that they've caught him, they're not satisfied. In fact, they think they've got the wrong enormous croc. The bigger one, the one causing all the harm, is still on the loose.
After the captured croc was forced to vomit, officials found no human nor water buffalo remains in his stomach. So yeah, wrong guy. Gulp. Lolong is already the biggest saltwater croc ever captured (the previous record holder was a measly 18 feet), so if Lolong turns out to be "Loshort" compared to his buddy still out in the wild, we could be in for a real surprise.
But know something? I'm all for safety and keeping danger away from any community, but I don't know ... do these massive, amazing creatures need to be captured? Lolong is going to spend the rest of his life in an eco-tourism park yet to be built (where's he going in the meantime?) and is slated to be the biggest attraction. Now that doesn't seem right. If these Herculean creatures are put in cages to be gawked at by tourists, that's unfair. (Let it be known I'm also not a fan of zoos in general ... the elephant houses are some of the saddest places on Earth.)
If these colossal crocs are causing a threat and are harming people, by all means, I understand that actions need to be taken. But can't they be moved? Relocated to another saltwater marsh a little less (humanly) populated? Yeah that still takes them out of their home and habitat, but at least it's not captivity
