A Puffer-fish was a fish that could inflate its own body in defence.[3]

It was a brown fish that could be found in the Black Lake of Hogwarts School of Witchcraft and Wizardry. The eyes of a Puffer-fish could be used as an ingredient in the Swelling Solution.[4]

Puffer-fish were also used as ingredients in the brewing of the healing potion Skele-Gro.[1]
