help Ringed Caecilian FAQ

Why do ringed caecilian babies eat their mother's skin?

The mother develops a nutrient-rich outer skin layer that her hatchlings scrape off with specialized temporary teeth. This behavior, called maternal dermatophagy, was documented in Siphonops annulatus.

Is a ringed caecilian a snake or a worm?

It is neither. Siphonops annulatus is a limbless amphibian related more closely to frogs and salamanders than to snakes or earthworms.

Where does Siphonops annulatus live?

The species occurs in South America and spends much of its life burrowing through moist soil and leaf litter. Its compact skull and elongated body are adaptations for moving underground.

Can ringed caecilians see underground?

Their eyes are reduced and provide limited vision compared with those of many surface-dwelling amphibians. They also use sensory tentacles between the eyes and nostrils to collect chemical information from their surroundings.
