Like other caecilians , they superficially resemble worms or snakes. Although they are
8-411: Is considerable debate among paleontologists and molecular geneticists concerning the phylogenetic relationship between amphibians, and indeed whether Amphibia is a monophyletic clade or a polyphyletic collection of diverse evolutionary lineages. The more limited debate (operating on the assumption that Amphibia is a monophyletic clade) is whether Caudata is more closely related to Anura (in
12-474: The most diverse of the caecilian families, the caeciliids do have a number of features in common that distinguish them from other caecilians. In particular, their skulls have relatively few bones, with those that are present being fused to form a solid ram to aid in burrowing through the soil. The mouth is recessed beneath the snout, and there is no tail. Many caeciliids lay their eggs in moist soil. The eggs then hatch into aquatic larvae, which live in seepages in
16-450: The soil, or in small streams. However, some species lack a larval stage, with the eggs hatching into juveniles with the same form as the adults, or else lack eggs and give birth to live young. Traditional taxonomy, which is reflected in the "Scientific Classification" box in this article, categorizes extant amphibia into three orders: Anura (frogs and toads), Caudata (newts and salamanders), and Gymnophiona (caecilians). However, there
