what are a group of sharks called

A group of sharks is most commonly called a shiver.

You’ll also sometimes hear:

• School of sharks.

• Frenzy of sharks.

• Herd, shoal, or gam of sharks (less common, more poetic/old-fashioned).

Fun extra: a group of baby sharks can be called a “wriggle” or a “nursery.”
