The cayenne caecilian is a species of fully aquatic amphibian which is found in parts of South America.

They are carnivores which will feed on invertebrates, frog larvae and eggs and fish.

Young hatch from their eggs inside their mother and will spend the first part of their larval stage here. They feed initially on the yolk from their egg and then on the mothers uterine wall.

The main threat to these animals is becoming trapped in fishing nets.

Read on to learn more about these amazing amphibians.

Appearance

What does the Cayenne caecilian look like?

The cayenne caecilian has a smooth body which is slender and a glossy black color. Running along the top of the body is a slight fin. On the underside it is dark grey. Running around the body are 80-95 well defined rings.

At the end of the body is a tail which is flattened like a paddle which helps to push them through the water.

An average individual of this species will measure 30-60cm (12-23.5in) long.

Diet

What does the Cayenne caecilian eat?


These animals are primarily carnivores. They will seek out aquatic insects and larvae, fish along with frog tadpoles and eggs.

Juveniles have regularly been recorded with decaying plant matter in their stomachs.

Range

Where can you find the Cayenne caecilian?

South America is the native home of the Cayenne caecilian. Here they can be found in the following countries – Brazil; Colombia; French Guiana; Guyana; Peru and Venezuela.

Their current status in Bolivia and Suriname is unknown.

Reproduction

How does the Cayenne caecilian produce its young?

Eggs will hatch inside the female and the larvae spend some time developing inside her body. She will then give birth to miniature adults.

While the young are developing inside their mother they will initially depend on their yolk. These animals will then feed on uterine wall secretions and the embryos of their dead siblings once they deplete the yolk.

At birth the young are equipped with gills which are attached dorsally. With 24-48 hours of birth these will fall off.

Behavior

What does the Cayenne caecilian do with its day?

These animals are entirely aquatic bust must breathe at the surface as adults. In one observation an individual remained fully submerged for 1.5 hours.

This species will forage at night.
