Distinguishing features

White, hair-like protrusions extending up to about 5 mm from dark-coloured branching bryozoan colonies (Celleporaria sp.) up to about 20 cm wide. Often found in shallow caverns.

Size

  • Up to 20 cm (bryozoan colony diameter)
  • Up to 0.5 cm (length of exposed portion of hydrozoan)

Synonyms

Comments

This is a symbiotic association between a bryozoan (forming the dark skeleton) and a hydroid (the white protrusions). The hydroid is likely to be a species of Zanclea which is always found in association with other sessile animals. (Dr Daniela Pica, pers.comm., 2018).
