Animals that do NOT yawn ?

[Blue Bubble]

Are there any animals you can think of that do not yawn ?

Birds ? Fish ? Insects ?

Platypus ?

If so, why do they not yawn ?

They don't read Iamme threads?

I'm going to ask the moderators to move this to the "old jokes" thread.

Fish can't yawn because they don't have lungs. The same is probably true for insects, although I'm not so sure, they definately have funny mouths that wouldn't be much good for yawning. I've never seen a bird yawn, but I have a feeling it's something funny about mammals so they probably don't. Platypussies are just ducks designed by committee so they come under the bird section.

If so, why do they not yawn ?

I think the more important question is why do we yawn?
