What are the main differences between a .....

Between a Duncan and a BTA?

I know ones considered an LPS, and the other is an anenome.

But, the both look very similar, both have a central mouth, and both eat food pieces put in their tentacles.

?

 

The Duncan is a stony coral.

 

As in LPS, Large polyp stony.

What makes them morphlogically different?

The Duncan and the anenome?

 

I believe that the anenome has no skeleton....that would be one?

 

Correct. Plus they're 2 different species of animal.

 

Almost all cnidarians have tentacles and a central mouth, the class anthazoa(all coral and nems are anthazoa) spends there whole life as polyps, where other classes, ctenophora, cubozoa, hydrozoa and one other i cant think of right now alternate between medusas and poylps.

a couple more differences are:
nems can move, duncans cant, nems are usually just one "polyp" where as when duncans split the head remains attached to the same skeleton.

 

OK! Thanks! That, was the kind of answer I was looking for.
(That was much easier than researching this, and I'm at work right now, and that was said concisely and better anyways)

haha thanks 8) If you get a chance, its quite interesting to research.
