Description

Dendrodoa grossularia is a solitary ascidian up to 2 cm long and about 1,5 cm in diameter. Its body has the form of a flat dome with an enlarging base but sometimes it can be erected and marble-shaped. The oral siphon is terminal, close to the atrial siphon and both are four-lobed. The test is reddish-brown. It can live solitary or in groups attached to rocks, shells or seaweeds.

Similar species

Distomus variolosus develops flat and the individuals appear to be agglomerated with a common coat. Polycarpa scuba also has a shape of a tea-pot but the siphons are larger, more apart and of square section.

Distribution

Dendrodoa grossularia is found from surface to 100 m deep in the Atlantic Ocean from the Arctic to the Southern coasts of Brittany, in the English Channel, the North Sea and West-Baltic.
