Flying seahorse

A flying seahorse is a variant of regular seahorse that is known for their ability to fly when provoked. They are found throughout lakes in Scotland, the most notable being the Black Lake.

History
A popular sport at Hogwarts School of Witchcraft and Wizardry in the 1990s was a game called "Flying Seahorse Fishing", in which one would use the seize and pull charm on the flying seahorses.

This was more than just recreational, however; they were a necessary ingredient in the girding potion, and Professor Severus Snape requested that each member of the class bring in three flying seahorses. Consequently, flying seahorse fishing was essential.
