Summary

Description

Halopteris filicina is a greenish-brown, fern-like seaweed that grows up to 10 cm in height. A number of individual stems, that are elongate and pointed towards the tip, grow from a holdfast that has a root-like appearance. Each stem bears alternately-placed side branches that, in turn, each bear short, pinnate branchlets. The density of these branches increases towards the upper part of the stem. Reproductive sporangia are ovoid in shape and positioned singularly at the axis of branchlets on short stalks.

Recorded distribution in Britain and Ireland

Halopteris filicina is widely distributed on southern and western coasts of Britain and Ireland.

Global distribution

Halopteris filicina is usually found in the Mediterranean and warm seas of the northern hemisphere.

Habitat

Halopteris filicina inhabits the lower shore and shallow water growing attached to rock, shells and large seaweeds.
