Shark

The shark (suborder Selachimorpha) is a type large carnivorous fish characterised by five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head.

For the second task of the Triwizard Tournament in 1995, Viktor Krum partially transfigured himself into a shark to complete it.

The Dukuwaqa, mascot of the Fijian National Quidditch team, is a magical creature capable of shape-shifting between the forms of a shark and a human.

Behind the scenes

 * Sharks were briefly mentioned in the W.O.M.B.A.T. test as a question about what would receive the heaviest punishment. Another one of the questions discussed using the Cruciatus Curse on a shark attacking a Muggle.
