caecilians

However, known caecilians do not even begin to approach the supposed size of this animal.

The eyes in caecilians are not well developed which is most likely to be because of their burrowing life style.

The skull is very different from those of other caecilians, giving the animal a broad, flat head.

The caecilians have two tentacles at their heads, which are probably used for smell.

Because caecilians have a lot of vertebrae, they can bend easily.

As caecilians evolved, their chromosomes are thought to have reduced in number.

They are primitive caecilians, lacking many of the derived characters found in the other families.

Caecilians in the family Typhlonectidae are aquatic, and the largest of their kind.

Further study is expected to clarify the taxonomic relationships between different species of caecilians.

This is also true for caecilians and aquatic mammals.

But they are actually slithering, tropical amphibians known as caecilians.

The larger caecilians look like snakes but their skin is smooth and not scaly.

Their eggs hatch into adult caecilians, with no larval stage in between.

They are thought to be more closely related to frogs and salamanders than to caecilians.

The diets of caecilians are not well known.

Adult frogs do not have tails and caecilians have only very short ones.

In the majority of species of caecilians, the young are produced by vivipary.

This is a feature unique to caecilians, but absent in the related family Rhinatrematidae.

Most Caecilians have lungs, except for two lungless species.

Caecilians rely on their smell to find food.

So caecilians employ a sort of water-balloon method of movement.

Green rods (a special type of visual cell, unknown in caecilians)

The Siphonopidae are the family of common caecilians.

Rhinatrema is a genus of caecilians in the Rhinatrematidae family.

All caecilians possess a pair of tentacles, located between their eyes and nostrils.
