What Does “A School of Sharks” Mean?
“School” is one of the most familiar collective nouns in the ocean, used loosely across dozens of fish species, and sharks are no exception. Unlike “shiver,” which is specific to sharks, “school” is borrowed straight from general fish terminology, a nod to the fact that sharks are, biologically speaking, fish themselves, even if their size and reputation set them apart from the smaller schooling species most people picture.
True schooling behavior, tight, synchronized, coordinated movement, is actually more common in smaller fish than in sharks. However, several shark species do form genuine schools under the right conditions. Scalloped hammerheads are the textbook example, gathering by the hundreds near seamounts during the day before dispersing to hunt alone at night. Juvenile sharks of various species also school together in nursery areas, likely for protection while they’re most vulnerable to predators.
Example: “A school of hammerheads circled slowly near the seamount, drawn together by the same current that brought the plankton.”
