Which animal group is called a plaque?

The term "plaque" is not typically used to describe an animal group. It is usually associated with a buildup of substances, like:

* Dental plaque: A sticky film that forms on teeth and contains bacteria.

* Atherosclerotic plaque: A buildup of cholesterol and other substances that can narrow arteries.

It's possible you might be thinking of a different term, perhaps "pack" or "pod". These terms describe groups of certain animals:

* Pack: A group of wolves, coyotes, or wild dogs.

* Pod: A group of whales, dolphins, or seals.

If you could provide more context or a different word, I might be able to help you further.
