|TUNICATA : APLOUSOBRANCHIA : Clavelinidae||SEA SQUIRTS|
Description: This sea squirt is small, only 2-3mm in size, solitary but in groups joined by creeping stolons.
Habitat: Usually in fairly strong tidal streams, attached to bedrock and wrecks, occasionally growing up hydroid and bryozoan colonies.
Ecology: The sea slug Colpodaspis pusilla has been observed possibly feeding on this species.
Distribution: Not uncommon in the Irish Sea and North Channel between Scotland and Rathlin Island. Also present in the North Sea and SW Ireland.
Similar Species: Quite easily recognised despite its small size because of the cross-shaped mark at the top of the test.
