What Animals Form a Pack?
The word usually reserved for wolves, borrowed by two very different hunters of the deep.
Which Animals Form a Pack?
Two very different swimmers carry “pack” as a listed collective noun: perch and sharks, joined by a third, unrelated flier: buzzards. It’s the primary term for neither — shoal and shiver are both more commonly used — but “pack” shows up consistently enough to count as a real, if secondary, alternate for both, and it’s not used loosely: it specifically describes coordinated, team-style hunting rather than simply swimming in a crowd.
Where Does “Pack” Come From?
“Pack” traces back to Middle English pak, itself borrowed from a Low Countries word (Middle Dutch or Flemish) meaning a bundle or parcel — the same root that gives English “package” and, much later, “backpack.” By the 14th century the word had already stretched from bundled objects to bundled animals, becoming the standard English term for wolves and hunting dogs that moved and attacked as a single coordinated unit. From there “pack” settled in as the go-to word for any group — animal or otherwise — that operates with that same tight, cooperative structure, which is exactly the quality that eventually pulled it underwater.
Pack of Wolves vs. Pack of Cards vs. Pack of Fish
Unlike collective nouns that borrow a word by pure coincidence, “pack” genuinely shares its root across every one of its uses. A pack of wolves, a pack of cards, and a pack of perch or sharks are all, at bottom, the same idea: a bundle of things that belong together and move as one. Fish only earn the label when they’re observed hunting cooperatively rather than schooling defensively — behavior documented in some perch populations and in several shark species that work together to corral prey.
Animal-by-Animal Breakdown
Perch: Most commonly called a shoal or school, like most schooling freshwater fish. “Pack” is reserved for the more deliberate, cooperative hunting behavior seen in some perch populations, where fish work together to herd smaller prey into tight, easy-to-pick-off groups rather than just moving as a crowd.
Sharks: Most commonly called a shiver — the term that tops nearly every list of shark collective nouns — with “school” used for calmer gatherings and “frenzy” for aggressive group feeding. “Pack” specifically describes species observed hunting cooperatively, coordinating to corral schools of prey fish rather than each shark hunting alone.
Buzzards: Most commonly called a wake (when feeding) or kettle (when circling in flight). “Pack” is a much looser, generic alternate here, without the behavior-specific precision it carries for perch and sharks — it’s simply another borrowed group word rather than a documented description of buzzard behavior.

Frequently Asked Questions
What animals form a pack?
Perch, sharks, and buzzards are all listed with “pack” as an alternate collective noun, though shoal, shiver, and wake/kettle are the more common terms respectively.
Is “pack” only used for wolves?
Wolves are the classic association, but “pack” has always meant any tightly coordinated group, which is why it also applies to hunting dogs, playing cards, and certain fish.
What is the most common collective noun for sharks?
Shiver is the term used most often for sharks, with school and frenzy also common depending on behavior.
Do perch really hunt in coordinated packs?
Some perch populations have been observed herding smaller prey fish cooperatively, which is the behavior “pack” is meant to describe, as opposed to simply schooling for safety.
Why do “pack” and “backpack” sound related?
Because they are related — both come from the same Middle Dutch root “pak,” meaning a bundle or parcel.
