Summary

Description

Nemertesia antennina is a colonial hydroid. The colony consists of up to 50 thick, stiff, erect, stems which can be up to 25 cm tall. The stems grow from a fibrous mass of rootlets. The stems bear bundles of 6-10 whorled side branches, these are incurved and widest at their bases. Nemertesia antennina is orange-buff in colour.

Recorded distribution in Britain and Ireland

Nemertesia antennina is widely distributed around the coasts of Britain and Ireland.

Global distribution

Nemertesia antennina is recorded in the northeast Atlantic, from at least the Faroes, Barents Sea and Iceland south through Mauritania to southern Africa, including the Mediterranean, Azores and Madeira.

Habitat

Nemertesia antennina is found attached to shells and stones on sandy bottoms from the shallow sublittoral into deeper waters offshore.
