Red ascidian

Aplidium solidum

Description:

Aplidium solidum is a compound tunicate that grows on rocks and other hard substrates. The tunic is gelatinous but firm in consistency, 2 to 3 cm thick.

Habitat:

Spotted in a tide pool at Tongue Point. It occurs on the west coast of North America from British Columbia south to California where it is common on rocks, especially among the holdfasts of kelp forests, and pilings. It occurs in the intertidal zone and at depths down to 40 metres.

Notes:

Aplidium solidum is a filter feeder. Water is sucked into the interior of the organism through an oral aperture and then expelled through a larger one, common to all the zooids in the system. Phytoplankton and other small organisms get trapped in mucus threads secreted by the endostyle.(Wikipedia)
