Always fun to watch and looking a bit like swimming golf balls, Pacific spiny lumpsuckers, Eumicrotremus orbis, have returned to our Puget Sound Fish exhibit. These odd fish get their names from an interesting feature: a sucker disk that they use to adhere to kelp, rock and other surfaces—which helps them resist the strong pull of marine currents. Weak swimmers, their camouflage helps them avoid detection by predators.
Pacific spiny lumpsuckers are found in marine waters from northern Washington to the Bering Sea, along the Aleutian Island chain to Siberia and northern Japan. Their maximum recorded length is about five inches, but they usually average between one and two inches.
Come see these interesting fish in person on your next visit!
