Which animal do not sit?

That's a tricky question! It depends on what you mean by "sit". Here's why:

* Many animals don't sit in the way humans do. They might rest on their haunches, lie down, or perch.

* Some animals don't have the physical structure to sit. For example, snakes or fish.

* Animals can learn to sit if trained. Dogs are famous for sitting on command, and even some birds can be trained to sit.

So, there isn't a single animal that never sits.

To make the question more specific, you could ask:

* Which animal doesn't sit naturally?

* Which animal can't sit because of its anatomy?
