Field Notes
Description:
Aka White Sea Cumber. This is a first time spotting on PN. About 6 cm in length (they can reach 10 cm). These are suspension feeders. They extend ten long, much-branched tentacles from the oral end and apply them to the substrate or wave them around in the water, trapping fine particles with mucus. The tentacles are then pushed into the mouth, where mucus and food particles are removed and swallowed. Two of the tentacles are smaller and are used for cleaning the larger ones. They are often covered in sea debris which helps to camouflage them from predators. They are preyed on by several species of starfish and some fish.
Habitat:
Spotted under a rock in a tide pool at low tide at Tongue Point Marine Sanctuary.
Notes:
Found in the northeastern Pacific Ocean, its range extending from Alaska to California. It is found on rocky shores in low intertidal and shallow subtidal zones, where it tends to hide itself in crevices and under boulders.
