Depth range Deep-sea context derived from a specimen depth data search [details]Depth range 323-912 m. [details] Distribution Southern Ocean: East Antarctic Peninsula, former Larsen Ice Shelf A area. [details] Etymology The specific epithet mucronata is the Latin adjective for 'pointed', and refers to the sharply pointed thin aristate-like tip on some of the large acicular spines of chaetigers 1-3. [details] Habitat Sediments coarse-grained in the upper 5 cm near the surface, overlying fine-grained silt and clay size sediments with depth, between 323-912 m depth. [details] Reproduction Sperm platelets observed in one large paratype measuring 10 mm long with 27 chaetigers. Individual sperm observed to have a short rounded nucleus, middle piece consisting of two spherical mitochondria and a long tail or flagellum. Morphology of juveniles described by Blake (2015: 82).
