Brasilotyphlus is a genus of caecilians in the family Siphonopidae.It was considered monotypic, containing only the species Brasilotyphlus braziliensis.However, two recently described species, Brasilotyphlus guarantanus and Brasilotyphlus dubium, have been placed in this same genus.
Caecilians feed on small subterranean creatures such as earthworms. The body is cylindrical and often darkly coloured, and the skull is bullet-shaped and strongly built. Caecilian heads have several unique adaptations, including fused cranial and jaw bones, a two-part system of jaw muscles, and a chemosensory tentacle in front of the eye. The ...
Caecilians are some of the least studied amphibians. Not much is known about their behavior and life history. Siphonops annulatus is highly fossorial, spending most of its life burrowed underground. A study found tunnels made by this species to go no deeper than 20 cm. This species uses a highly ossified skull to help burrow into the ground. [5]
Just the big, sharp teeth are daunting; as Baker put it, “They have a mouth full of steak knives.” ... One of nearly 200 caecilian species, Kaup’s aquatic caecilian is a legless amphibian ...
Siphonopids are oviparous caecilians, meaning they lay eggs. They have imperforated stapes and no inner mandibular teeth. Like species of some other caecilian families, their skulls have relatively few bones, with those present being fused to form a solid ram to aid in burrowing through the soil.
Unlike earthworms, caecilians possess a prominent mouth, nostrils, and, uniquely amongst vertebrates, a pair of retractable tentacles, one on each side of the head, between the eye and nostril. The snout of the Sagalla caecilian is rounded, with short, globular tentacles, and a relatively large mouth, with two rows of teeth in each jaw.
Adult Oscaecilia often exceed 60 cm (24 in) in total length. [3] The diagnostic characters of Oscaecilia include eyes that are covered by bone, presence of splenial teeth, absence of true tail, and a tentacular opening that is directly below the nostril, much closer to it than to the eye.
