Open encyclopedia reference
Eumicrotremus pacificus, commonly known as the spotted lumpsucker or the balloon lumpfish, is a species of lumpfish (family Cyclopteridae) native to the northwestern Pacific Ocean. It occurs in the Sea of Okhotsk, the Sea of Japan, the East China Sea, and the waters off Hokkaido and the Kuril Islands.
E. pacificus may be confused with the closely related Eumicrotremus orbis, which has an overlapping distribution. However, E. pacificus is typically larger, reaching up to 20 cm (7.9 in) in total length. It is generally yellow to orange in colour with small dark spots, and its tubercles are usually smaller and less pronounced than those of E. orbis, giving it a less spiny appearance.
