Summary

Description

Dendrodoa grossularia is a solitary, reddish-brown sea squirt, up to 2 cm long and 1.5 cm in diameter, which occurs singly or aggregated in dense, bumpy clusters. It is firm to the touch and the shape of individuals varies from flattened and rounded on a spreading base when solitary, to upright, elongated and cylindrical when aggregated. The two short but conspicuous siphons are square or four-lobed in outline when partly contracted, but round and flared when actively pumping.

Recorded distribution in Britain and Ireland

Widely distributed, and locally common, around British and Irish coasts. Not recorded in northeast Scotland, the coast south of the Humber to the Stour and the south coast of Ireland.

Global distribution

Generally distributed from the Arctic, round the northeast coast of America, throughout northwest Europe and Britain, including the Scilly Isles and the Brittany peninsula.

Habitat

Found on the lower shore and sublittorally to a depth of 600 m on a variety of substrata including rock, shell, other ascidians and algae. It is particularly abundant and dominates rocks in two contrasting situations: in surge gullies and caves exposed to severe wave action and in locations entirely sheltered from wave action where tidal streams are moderate to strong.

Identifying features

  • A solitary species occurring singly or in dense, bumpy clusters reddish-brown.
  • 2 short, conspicuous siphons.

Additional information

Also known as the gooseberry sea squirt. This species is similar in external appearance to Distomus variolus, Stolonica socialis, and Polycarpa scuba. The internal anatomy is important in distinguishing between species. The siphons of Dendrodoa grossularia are more conspicuous than those of Distomus variolosus.
