Left fish radical, simplified from
魚 (the four-dot
灬 tail compressed to a single horizontal stroke). It indexes
魾 in the fish-name family:
鲤 carp,
鲨 shark,
鲸 whale,
鳗 eel. Any character with
鱼 on the left names a specific fish species — and
魾 is the goonch catfish, a giant predatory bagrid of South Asian rivers.
