Eualaria is a monotypic genus of subtidal kelp containing the species Eualaria fistulosa (synonym Alaria fistulosa).[1] Its native Alaskan name is Kausam.
Description
The entire plant consists of a holdfast and a single very large frond or lamina. In one instance, at Anchor Point, Cook Inlet, Alaska, a lamina collected by Griggs and Rigg was 22 meters (72 ft) long by 170 cm (67 in) wide.[2] Other laminae have been measured as wide as 252 cm (99 in)[3] and others as long as 25 m (82 ft)[4] Unusually among kelps, the laminae of Eualaria have midribs.
Distribution and habitat
It is native to the northern Pacific Ocean, where it ranges from the coast of Alaska and the Aleutian Islands to the Commander Islands, Russian Far East, Sakhalin, Kuril Islands, and Japan. It grows in the subtidal zone to a depth of 10 meters.[1]
