Hannah Johnson, University of Bristol The ancestors of today's crocodiles colonized the seas during warm phases and became extinct during cold phases, according to a new Anglo-French study which establishes a link between marine crocodilian diversity and the evolution of sea temperature over a period of more than 140 million years. The research, led by Dr. Jeremy Martin from the Université de Lyon, France and formerly from the University of Bristol, UK is published this week in Nature...

Dartmouth-led Study May Resolve Evolutionary Debate Of Turtles
2014-05-06 03:59:54

Dartmouth College Turtles are more closely related to birds and crocodilians than to lizards and snakes, according to a study from Dartmouth, Yale and other institutions that examines one of the most contentious questions in evolutionary biology. The findings appear in the journal Evolution & Development. The research team looked at how the major groups of living reptiles, which number more than 20,000 species, are interrelated. The relationships of some reptile groups are well...

Alligator Sound Perception Comes From Air-Filled Canals Between Their Ears
2014-03-28 09:21:20

Brett Smith for redOrbit.com - Your Universe Online For an animal without external ears, alligators have a strong sense of directional hearing and a new study published on Wednesday in the Journal of Experimental Biology has revealed that the reptiles’ refined hearing is a result of large, air-filled canals connecting two middle ears. "Mammals usually have large moveable ears, but alligators do not, so they have solved the problems of sound localization a little differently,” said...

A University of Maryland-led team of biologists shows that alligators can keenly detect the direction of sounds because of large, air-filled channels connecting the two middle ears. Birds have a similar configuration and the mechanism probably originated with archosaurs, the shared ancestors of modern crocodilians and birds. College Park, Md (PRWEB) March 26, 2014 By reptile standards, alligators are positively chatty. They are the most vocal of the non-avian reptiles and are known to be...

Crocodiles Really Can Climb Trees
2014-02-11 08:50:34

University of Tennessee at Knoxville Vladimir Dinets, a research assistant professor in the University of Tennessee at Knoxville Department of Psychology, is the first to thoroughly study the tree-climbing and -basking behavior When most people envision crocodiles, they think of them waddling on the ground or wading in water — not climbing trees. However, a University of Tennessee, Knoxville, study has found that the reptiles can climb trees as far as the crowns. Vladimir Dinets, a...

Video Footage Reveals Novel Insights Into Crocodilian Foraging Behaviors
2014-01-16 07:46:56

Public Library of Science Animal-borne camera reveals that alligators may attempt to capture prey most often at night, even though the calculated probability of catching prey is highest in the morning, according to a study published in PLOS ONE on January 15, 2014 by James Nifong from the University of Florida and colleagues from other institutions. Observing the behaviors of dangerous and cryptic predators like alligators is no easy task, so scientists used animal-borne cameras to...

Crocs Use Lures To Catch Birds
2013-12-05 13:03:19

Brett Smith for redOrbit.com - Your Universe Online Alternately lethargic and viciously violent, crocodilians are not often thought of as cunning, duplicitous predators. However, a new study in the journal Ethology, Ecology and Evolution has found that these massive reptiles sometimes use sticks and twigs to lure in unsuspecting birds, particularly during nest-building season. "Our research provides a surprising insight into previously unrecognized complexity of extinct reptile...

Banana Farms Contaminating Costa Rica's Crocs
2013-09-19 12:18:12

Wiley Shoppers spend over £10 billion on bananas annually and now this demand is being linked to the contamination of Central America's crocodilians. New research, published in Environmental Toxicology and Chemistry, analyses blood samples from spectacled caiman in Costa Rica and finds that intensive pesticide use in plantations leads to contaminated species in protected conservation areas. "Banana plantations are big business in Costa Rica, which exports an estimated 1.8 million...

Ancient Crocodile Diversity
2013-09-11 12:31:02

[ Watch the Video: Crocodiles Thrived During Prehistoric Times ] Brett Smith for redOrbit.com - Your Universe Online Ancient relatives of crocodiles had a wide range of habitats and ecosystems, with some species built like domestic dogs and others built for swimming through the open seas. Using a combination of morphological and biomechanical metrics to analyze these ancient crocodilians, a new study from researchers at the University of Bristol in the UK identified distinct trends...

Chinese Alligator Genome Sequencing Complete
2013-08-10 05:29:43

April Flowers for redOrbit.com - Your Universe Online Scientists from Zhejiang University in China and  BGI Shenzhen have completed and analyzed the genomic sequence of the endangered Chinese alligator (Alligator sinensis) – the first published crocodilian genome. The findings, published in Cell Research, provide plausible explanations of how terrestrial reptiles adapt to aquatic environments and temperature-dependent sex determination (TSD). The Chinese alligator is critically...

The Gharial, Gavialis gangeticus, is one of two surviving members of the family Gavialidae. The Gharial (also known as gavial) is found in small numbers in India and other small populations in the Kaladan and Ayeyarwady River basins in Myanmar. Most gharials are adapted to calmer areas in deep fast moving rivers. They rarely leave the water and do so only to bask in the sun or nest on sandbanks near the river. The gharial is the second-longest of all living crocodilians. A large male can...

The Spectacled Caiman, Caiman crocodilus, is a crocodilian reptile found in much of Central and South America. It lives in a range of lowland wetland and river habitat and can tolerate salt water as well as fresh. Due to this adaptable behavior, it is the most common species of caiman. Males of this species are between 6 and 8.2 feet long, while females are smaller, usually around 4 and a half feet long. The species' common name comes from the bony ridge between the eyes, which give the...

The False Gharial or Malayan Gharial, Tomistoma schlegelii, is a fresh-water reptile, resembling a crocodile. This animal is native to six river systems in Sumatra and Malaysia. It is also found in Borneo, Java, Vietnam, Thailand and possibly Sulawesi. In Thailand, the Gharial has not been seen since 1970. There have also been fossils found in Southern China that indicate it once survived there as well. The female Gharial usually matures at 17-118 inches in length . The False Gharial,...
