Pacific Spiny Lumpsuckers on Display at Aquarium of the Pacific in Southern California

Ninety Eumicrotremus orbis were born at the aquarium in 2011.

The Aquarium of the Pacific in Long Beach, California has put on display 90 captive bred Pacific spiny lumpsuckers (Eumicrotremus orbis) that were born in 2011. A solitary species, the lumpsuckers are about the size of a golf ball and don’t grow larger than about 5 inches in length, and the average size is less than 2 inches. They live from one to three years.

They are called lumpsuckers in part due to an adhesive disk that enables them to attach to surfaces in their habitats and wait for food to come their way. Lumpsuckers are not good swimmers and the disk helps them to stay stationary. Their native habitats include waters off Washington state, mainland Asia, Japan’s northern islands as well as the Aleutian Islands.

The aquarium feeds the Pacific spiny lumpsuckers finely chopped squid, shrimp, clams and fish as well as krill and live mysid shrimp.
