What Animals Form a Shoal?
A word for schooling fish that, unexpectedly, also fits a huddle of baby geese.
Which Animals Form a Shoal?
“Shoal” is the standard term for four schooling fish — bass, mackerel, minnows, and pilchards — plus a genuinely surprising fifth entry: goslings, baby geese, which are sometimes described the same way when paddling together in a tight cluster on the water’s surface.
Where Does “Shoal” Come From?
The fish-group “shoal” and the fish-group “school” are, remarkably, the same word wearing two different spellings — both trace back to Middle Dutch schole, meaning a troop or group. English absorbed the word twice, through slightly different paths, and simply kept both spellings in use rather than picking one, which is why “shoal” and “school” are used almost interchangeably for fish today.
Shoal (Fish) vs. Shoal (Shallow Water) vs. School
Confusingly, English also has a completely unrelated word “shoal” meaning a shallow, sandy stretch of water — a sandbar or shallows a boat might run aground on. That word comes from a different root entirely, Old English sceald, meaning “shallow.” It’s pure coincidence that fish gathering in a shoal are also often found in shallow water — the two “shoals” aren’t etymologically connected at all, even though they sound like they should be.
Animal-by-Animal Breakdown
Bass, Mackerel, Minnows, and Pilchards: “Shoal” (and its twin, “school”) is the genuine standard term for all four, describing the loosely coordinated groups these fish naturally form for safety and feeding.
Goslings: Usually described as a “brood” while still with their parents. “Shoal” is a much rarer, more visual alternate for goslings paddling together in a tight bunch on the water — a group of chicks briefly borrowing a fish word because of how they look, not because of any real relation.

Frequently Asked Questions
What animals form a shoal?
Bass, mackerel, minnows, and pilchards all use “shoal” as their standard term, and goslings are sometimes described the same way as a rarer alternate.
Is shoal the same as school for fish?
Essentially yes. Both trace back to the same Middle Dutch word, schole, and are used almost interchangeably for fish today.
Why is shoal used for goslings?
Goslings paddling together in a tight cluster on the water resemble a shoal of fish schooling near the surface, which is likely where the borrowed usage comes from.
Is a shoal of water related to a shoal of fish?
No, they’re unrelated words. The shallow-water “shoal” comes from Old English sceald, a completely different root from the fish-group term.
What is the usual term for a group of goslings?
“Brood” is the standard term for goslings while with their parents; “shoal” is a much rarer alternate.
