泥鰌

Unknown. Historical sources from the Muromachi period spell this in kanji as 土長, and in historical kana as どぢやう (dodyau). Spellings such as どぜう (dozeu) were apparently later innovations.[1][2]

Theories suggest that the name may refer to the fish's apparent ability to thrive in muddy conditions. The modern kanji spelling is an example of jukujikun (熟字訓).
