Why Are Anemones under Inverts?

OldandNew · 12-11-2004, 11:18 PM

I'm placing the question here because it may be a stupid question and I don't think I'll get beat up here with it (not that I would elsewhere, however).

Why are Anemone in the Invert section and not under Corals? Are they not Kith and Kin with the Corals?

Aren't they technically a fish?

I'm over my head already, and you want me to answer that

No spinal column?

heh. Seriously, probably should be in corals.

Oh well. lol

Well, perhaps technically, but, as a casual reefer....I have always looked for anemones under inverts and here is my convoluded thinking....

fish - spine aka...vertebrate

anemone - no spine ...aka Invertebrate

coral - hard skeletal structure, or attached to a hard skeletal structure, or a soft coral that is permanently attached to a rock or such.

also, corals are non-motile (non moving) inverts while anemones are motile (moving) inverts.....

I don't know if that makes much sense but, we less technically informed go to invert sections to look for info on anemones....right or wrong...

We don't all think..."hmmm, cnidaria, animals with stinging cells, that is where the anemone would be..." Well, you know what I mean!!! LOL!

I hear ya Sue!

That's some of the stuff I wrestled with initially.
Now I am back to being confused.

Ya know, I was born confused, and therapy really hasn't helped! LOL. I think I need to go drink some of that Southern Comfort Egg Nog I got in the fridge downstairs.....mmmmmm

It will all make sense in an hour!

i have a question on corals being non-motile. i always thought some corals do move. i have xenias that move and i thought they were corals. unless im wrong and they are not corals. and i have shrooms that move and i thought they were classified as corals as well. i may be wrong, but we are all here to learn right!

Not all corals are non-motile. My leathers don't necessarily "move", but I seen them grow away from their original spot, leaving bits of tissue behind. Plate corals also "move" so there are always going to be exceptions.

Personally, I've always thought of anemones as invertibrates.
