A group, or many Barracudas found together are called a what?

A barracuda is a large, predatory, ray-finned fish known for its fearsome appearance and ferocious behaviour.

Barracudas are fast-swimming, with streamlined, torpedo-shaped bodies and razor sharp teeth. They can be found in the depths of the ocean, as well as in coastal areas and coral reefs.

Many barracuda are known as a “battery". Although attacks on humans are very rare, this is the kind of battery you don’t want charging your way!
