What is a school of sharks called?

A school of sharks is referred to as a school, shiver, gam, frenzy or herd. While some species of sharks are solitary hunters, many species spend their lives in large groups.

Hammerhead and blue sharks often segregate themselves in groups by gender and age. Males and females spend their entire lives separate, only coming together when it is time to mate. Social behavior among great whites is based primarily on size. Larger sharks dominate smaller ones, and females have more social power than males. However, long-term residents of a territory are not often displaced by new arrivals even if the newcomers are larger. Great white sharks use rank as a way to avoid confrontation and combat.
