Scolecomorphidae

provided by wikipedia EN

The Scolecomorphidae (from Greek: σκώλεκώς skólekós, 'wormlike' and Greek: μορφή morphḗ, 'form') are a family of caecilians[1] also known as tropical caecilians, buried-eyed caecilians,[1][2] or African caecilians.[3] They are found in Cameroon in West Africa, and Malawi and Tanzania in East Africa.[1] Caecilians are legless amphibians which superficially resemble worms or snakes.

Scolecomorphids have only vestigial eyes, which are attached to the base of a pair of tentacles underneath the snout. Unlike other caecilians, they have only primary annuli; these are grooves running incompletely around the body, giving the animal a segmented appearance. All other caecilians have a complex pattern of grooves, with secondary or tertiary annuli present. Also uniquely amongst tetrapods, the scolecomorphids lack a stapes bone in the middle ear.[4]

At least some species of scolecomorphids give birth to live young, retaining the eggs inside the females' bodies until they hatch into fully formed offspring, without the presence of a free-living larval stage.[4]

Taxonomy

Just six species of scolecomorphids are known, grouped into two genera, as follows:[1][2]
