Eulagisca uschakovi is a giant scale worm known from the Antarctic, in waters such as off Mac.Robertson Land, Palmer Archipelago and the Weddell Sea, at depths of 10 to 920m. ^[2]

Description

Specimens can grow to up to around 190 mm in length and have 39 segments with 15 pairs of elytra. The body is brownish at the mid-dorsum. The elytra are large and thin, with brownish splashes of pigmentation and fringe of sharp, pointed papillae along their margin. Wide, ovular prostomium with the median antenna with a large ceratophore in an anterior notch and lateral antennae inserted terminally on anterior margin of prostomium. Notochaetae are capillary-type and thicker than the capillary neurochaetae. ^[2]
