Been talking with Randman on a different thread about human tails and fetuses and whatnot, and it got me thinking.
​
Are there any mammals that don't have tail bones? I don't mean they don't have tails, I'm sure there are a few. But, can anyone think of any species that don't have at least a completely internal tailbone like we do?
​
For that matter, I'm trying to think of reptiles/amphibians that either don't have tails or never had tails during their various stages (ie tadpoles).
​
How universal are tails? Seems like a whole lot of them out there.
​
Stands to reason, obviously, since I don't think there are any tailless fish (save the filet o' variety).
​
But, in the interest of good science - can anyone think of any completely tailless animals?

Let me refine
Totally didn't think about corals or insects as animals.
​
Let's lessen the scope.
​
Can anyone think of any member of Cordata that lacks a tail (either obvious or not)?
