The Question:

What is a group of rhinoceroses called?

The Answer:

We get questions like this a lot. We answer most of them by sending people to our very helpful Animal Group Terminology table.

However, this list doesn't include every animal, and, unfortunately, we can't answer every question about animals not on this list. But for some reason an inordinate number of users need to know what to call a group of rhinoceroses.

It is called a crash.
