caecilian A type of amphibian that has no legs.

Not only is this the sole lungless caecilian, it's by far the largest lungless, four - limbed vertebrate known.

In their newly published checklist the researchers have listed 49 species of frogs and toads, as well as one caecilian species — a limbless, snake - like amphibian.

Now the same team have screened over 5,000 amphibians from four continents to ascertain the threat the new disease presents to other species.The results, published today in the journal Science, show that B. salamandrivorans is very dangerous to salamanders and newts, but not to frogs, toads and snake - like amphibians called caecilians.

The researchers also looked at amphibian evolutionary history, which considers all the frogs, salamanders and caecilians that have existed over millions of years.

Small fossils about 220 million years old found along steep red slopes in Colorado represent a near - relative of modern animals called caecilians, says vertebrate paleontologist Adam Huttenlocker of the University of Southern California in Los Angeles.

Nussbaum, a University of Michigan zoologist who specializes in caecilians, the little - known group of amphibians to which this beast belongs, learned of the specimen from one of his graduate students.

Most other known caecilians are burrowing creatures, but Nussbaum believes the new specimen's bizarre features suit it to life at the bottom of cool, high - oxygen mountain streams.

Caecilians have ring - shaped folds of skin called annuli, small eyes covered by skin and sometimes bone, and a pair of tentacles.

Frogs (e.g., Woodhams et al. 2003, Retallick and Miera 2007; Andre et al. 2008), salamanders (e.g., Weinstein 2009), and caecilians (Raphael and Pramuk 2007, unpublished) have been reported to clear Bd infections when kept at higher temperatures for a time.

This group includes all types of birds (parrots, love birds, cockatoos, finches, chickens, toucans), reptiles (turtles, tortoises, lizards, snakes), amphibians (frogs, salamanders, and caecilians), fish, pocket pets or small mammals (rabbit, guinea pig, chinchilla, hamster), backyard mammals (pigs, goats), other mammals (lions, foxes, bears, primates), and virtually any other animal with the exception of some domestic animals (dogs, cats, cows, horses).

Named Chinlestegophis jenkinsi, the new fossils act as a sort of «missing link,» connecting caecilians to stereospondyls, the most diverse amphibian group during the Triassic Period over 200 million years ago.

Although there are currently about 200 known species of caecilians, little is known about their early evolution.

Caecilians are one of the most mysterious amphibians on earth.

The ancient amphibian probably ate insects and possessed tiny but functional eyes, differentiating it from modern caecilians, as many modern species either do not have eyes or hide their eyes under moist skin.

«Caecilians are hard to find in the fossil record because most are so small,» added Adam Huttenlocker, an assistant professor in the Department of Integrative Anatomical Sciences at the Keck School of Medicine of USC.
