lumpfish; lumpsucker
A marine fish of the family Cyclopteridae, especially Cyclopterus lumpus. The name comes from its round, dumpling-like body.
Lumpfish live in the cold northern seas.
I saw a lumpsucker at the aquarium.
Kanji spelling exists but is rarely used; the word is usually written in kana.
From 団子 (dango, 'dumpling') + 魚 (uo, 'fish'), referring to its round, dumpling-like shape. The exact derivation is uncertain, but the name is descriptive.
