What Is a Group of Sharks Called?
The ocean’s most feared predator has a collective noun as sharp as its reputation.
A group of sharks is most often called a shiver, with school, shoal, and pack used as alternates. Sharks (superorder Selachimorpha) have patrolled the oceans for over 400 million years, predating dinosaurs by roughly 200 million years.

What Is a Group of Sharks Called?
Shiver is the term most closely associated with sharks, likely inspired by the way a group cutting through open water can send a genuine chill through anyone watching from the surface. School and shoal are more general fish-grouping terms that also apply to sharks, especially species like hammerheads that gather in large, loosely coordinated numbers. Pack shows up occasionally too, evoking the coordinated hunting behavior seen in a few social species.
Where Did the Name Come From?
Most English collective nouns for animals trace back to medieval hunting terminology, particularly the Book of Saint Albans (1486), but shark-specific terms like “shiver” appear to be newer additions from later wordlist traditions rather than the original terms of venery. Sharks themselves are far older than the language used to describe them, cartilaginous fish that have remained largely unchanged in body plan for hundreds of millions of years, long before humans existed to name them at all.
Shark Facts
- Ancient lineage: Sharks first appeared over 400 million years ago, predating dinosaurs, trees, and even Saturn’s rings by some estimates.
- Cartilage, not bone: A shark’s skeleton is made entirely of cartilage, lighter and more flexible than bone, which is part of why they move so efficiently through water.
- Electric sense: Sharks can detect the faint electrical fields produced by other animals’ muscles using organs called the Ampullae of Lorenzini.
- Not all keep swimming: The “must swim constantly or die” myth applies only to certain species; many sharks can pump water over their gills while resting on the seafloor.
- Size range: Sharks range from the dwarf lanternshark, small enough to fit in a human hand, to the whale shark, the largest fish in the ocean.
Example Sentences
- A shiver of hammerheads circled beneath the boat as the divers slowly descended.
- Marine biologists tracked a school of reef sharks patrolling the same stretch of coral for weeks.
Other Names for a Group of Sharks
Shiver remains the most distinctive and commonly cited term specifically for sharks. School and shoal are borrowed from general fish terminology and are used more loosely, while pack is the least common of the four, typically reserved for describing coordinated hunting behavior in a small number of species.

Frequently Asked Questions
What is a group of sharks called?
Most often a shiver, with school, shoal, and pack used as alternates.
Do sharks have to keep swimming or they’ll die?
Only true for some species. Many sharks can pump water over their gills while resting on the seafloor.
What is a shark’s skeleton made of?
Cartilage, not bone, which makes sharks lighter and more flexible in the water.
How old are sharks as a species group?
Sharks first appeared over 400 million years ago, predating dinosaurs by roughly 200 million years.
Are sharks dangerous when grouped together?
Most species pose little threat to humans even in groups; shark attacks are rare and typically involve a single animal, not a coordinated shiver.
More Than Just Jaws…
A shiver of sharks is one of the ocean’s oldest success stories, cartilaginous survivors that outlasted the dinosaurs and still patrol every ocean on Earth today.
