The Scolecomorphidae are the family of tropical caecilians (Frost) or African caecilians (ITIS). They are found in Cameroon in West Africa, and Malawi and Tanzania in East Africa. 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 caecilians, the scolecomorphids lack a stapes bone in the middle ear. 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.〔 == Taxonomy == Just five species of scolecomorphids are known, grouped into two genera, as follows: Family Scolecomorphidae * Genus ''Crotaphatrema'' (Nussbaum, 1985). * * ''C. bornmuelleri'' (Werner, 1899), Bornmuller’s caecilian, Cameroon 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scolecomorphidae」の詳細全文を読む スポンサード リンク
