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.
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 ...
Dermophis mexicanus, also known commonly as the Mexican burrowing caecilian or the Mexican caecilian, and locally as the tapalcua or tepelcua, is a species of limbless amphibian in the family Dermophiidae. The species is native to Mexico and Central America, where it burrows under leaf litter and plant debris.
The Ceylon caecilian grows to about 23 to 40 cm (9.1 to 15.7 in) long and resembles a large earthworm. The skin is formed into over 300 transverse folds which give the caecilian the appearance of being segmented. The head has a rounded snout and a pair of extensible tentacles near the mouth, rather closer to the eyes than to the nostrils. The ...
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 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]
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.
Rhinatrematidae is a family of caecilians, also known as the Neotropical tailed caecilians, American tailed caecilians. or beaked caecilians. They are found in the equatorial countries of South America. [1] [2] They are usually regarded as the most basal of the caecilian families, with numerous characteristics lacking in the other groups.
