At first, they feed on the yolks of their eggs, but they develop rasping teeth and later consume glandular secretions produced by the lining of the oviduct. Birth takes place after about eight months and the juvenile caecilians shed their temporary teeth and develop their

The
Cayenne caecilian is an elongated, dark grey, black or steely blue amphibian with no limbs. The body is flattened laterally and has a number of transverse folds, giving it a segmented appearance. A long fin runs along its back, and it grows to a length of 30 to 55 cm (12 to 22 in). It

The
Cayenne caecilian lives in shallow streams and rivers. It spends the day in a communal burrow, emerging at night to hunt through the sediment for small invertebrates, such as insect larvae and shrimps. It also eats small fish. It has no functional eyes and probably detects its
