Pacific Spiny Lumpsuckers on Display in the Northern Pacific Gallery

August 2, 2012

About ninety Pacific spiny lumpsuckers (Eumicrotremus orbis) born at the Aquarium in 2011 are on view in the Rocky Reef exhibit in the Northern Pacific Gallery. Lumpsuckers can be as small as golf balls and usually do not grow larger than two inches in length. They have a unique adhesive disk that allows them to attach to various surfaces in their habitats.

An inefficient swimmer, the lumpsucker uses its suction disk to attach to rocks, kelp, and eelgrass. They are found in the ocean waters off the Washington State coast, the Asian mainland, the northern islands of Japan, and the Aleutian Islands.

At the Aquarium, the lumpsuckers are fed a mixture of finely chopped squid, shrimp, clams, and fish, as well as small krill and live mysid shrimp. They usually live one to three years and are solitary by nature.
