caecilian

caecilian , any of the legless, tailless tropical amphibians of the family Caecilidae. Most adult caecilians resemble earthworms superficially but have vertebrate characteristics such as jaws and teeth. They range in size from 7 in. to 4.5 ft (18 cm-140 cm); most are about 1 ft (30 cm) long. Their bodies are ringed with grooves, which in some species contain small scales imbedded in the skin; possession of scales is a primitive amphibian trait. There is a groove on either side of the head, each containing a retractable sensory tentacle. The eyes of caecilians are nearly functionless, and some species are eyeless. Caecilians are found in swampy places in most tropical parts of the world, but are seldom seen because of their burrowing behavior. They eat small invertebrates such as termites and earthworms. A few species remain aquatic as adults and resemble eels. There are about 50 species of caecilians, divided into 16 genera. They are classified in the phylum Chordata , subphylum Vertebrata, class Amphibia, order Gymnophiona (or Apoda), family Caecilidae.

Caecilian (d. before 343), Bp. of Carthage from 311 or perhaps 307. His importance lies in his part in the opening stages of the Donatist controversy. The rigorist party at Carthage consecrated a rival bishop, urging that Caecilian's consecration was invalid on the ground that he had been consecrated by a ‘traditor’.
