Comprehensive Description
Description
This hydroid consists of fine, sparsely branched stems bearing paired hydrothecae. The hydrothecae are triangular in shape, with a hair-like outer cusp. The stems are usually clustered into small bushes, and are golden-brown in colour. Typically colonies measure 100mm in height. This is a distinctive species, with finer branches than most Sertulariid hydroids.

This species is especially characteristic of the infralittoral zone where strong wave action or tidal streams are present. It normally grows on stipes of the kelp, Laminaria hyperborea, but may also attach directly to bedrock.
