A sea squirt (Perophora japonica)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Colonies of small, translucent zooids (approximately 4 mm long) budded from stolons and generally rather closely packed. Young parts of colony are yellow or greenish-yellow. Stolons may bear angular, often star-shaped, terminal buds, which are bright yellow.

Recorded distribution in Britain and Ireland

Recorded in Queen Anne's Battery Marina, Plymouth Sound; the Fleet, Dorset approximately 130 km from Plymouth, and in Guernsey.

Global distribution

Also recorded from the English Channel coast of France. Originally described in Japan, and reported from Korea.

Habitat

At Plymouth, it grows on fucoid algae, hydroids and artificial settlement panels on the underside of a floating pontoon. In France, it is reported growing on Sargassum muticum, fucoid algae, Laminaria spp., sponges, solitary ascidians, oysters, and directly on floating pontoons.
