Careproctus ovigerus
Careproctus ovigerus, commonly known as the abyssal snailfish, is a species of snailfish found in the northeastern Pacific Ocean. It is found at depths of off northern British Columbia and off Washington state. Description. Like other members of the family Liparidae, "C. ovigerus" is an elongated fish with a gelatinous skin with no scales. The pectoral fins are large and used for locomotion and the pelvic fins are modified into an adhesive disc. "C. ovigerus" grows to a maximum length of . The dorsal fin has no spines and 40 to 45 soft rays and the anal fin has  no spines and 35 to 36 soft rays. The pelvic disc is 26 to 38% of the total length of the fish. Fish in the genus "Careproctus" can often be distinguished by the pore pattern made by the cephalic pores (the nasal, maxillary, preoperculomandibular and suprabranchial pores); in this species the pattern formed is 2–6–7–1. This species closely resembles "C. lycopersicus" and "C. kamikawai", but those two species have tri-lobed teeth in several broad bands while "C. ovigerus" has simple, sharp recurved teeth in a single narrow band. Behavior. "Careproctus ovigerus" is thought to be a mouth brooder as  the holotype, a male, was found to be carrying two developing eggs in his mouth. Two immature females of standard length had undeveloped ovaries containing many small eggs in diameter, while larger, mature females had fewer, large-yolked eggs in their ovaries, the egg being some in diameter.
