Comprehensive DescriptionRead full entry
DescriptionThis solitary ascidian is found buried in coarse gravel, sand or muddy sand with only the siphons visible. The siphons are delicate, nearly transparent when extended and tapered. They are placed close together on the uppermost part of the rounded body. The test is covered with firmly attached gravel or shell particles. Molgula oculata is a similar but larger species which has a characteristic bare area around and between the siphons when it is expanded. It lives in clean coarse gravel or shell gravel. Eugyra arenosa is also similar but lives in clean fine sand and has a test covered in sand particles.
