Taxonomy
- Kingdom: Animalia
- Phylum: Chordata
- Class: Actinopterygii
- Order: Scorpaeniformes
- Family: Liparidae
- Genus: Paraliparis
- Species: Paraliparis kocki
The species is part of the diverse genus Paraliparis, which comprises numerous deep‑sea snailfishes distributed in cold, high‑latitude waters.
Description
Paraliparis kocki is a small, elongated snailfish. Specimens reported in the original description reach a standard length of approximately 7–9 cm. Like other members of its family, it possesses a soft, gelatinous body, reduced or absent scales, and a ventrally positioned mouth. The dorsal and anal fins are continuous with the caudal fin, and the pectoral fins are relatively large, aiding in maneuverability near the seabed.
Distribution and Habitat
The species is known from deep‑water habitats of the Southern Ocean. Specimens have been collected at depths ranging from roughly 500 to 1,200 meters, indicating an adaptation to cold, high‑pressure environments typical of Antarctic and sub‑Antarctic benthic zones.
Etymology
The specific epithet kocki honors an individual with the surname Kock, who is recognized for contributions to Antarctic marine research or for assisting in the collection of the type specimens. The original description does not provide a detailed dedication, but the naming follows the customary practice of commemorating scientists or contributors in taxonomic nomenclature.
