Words To Use Today: pteropod/sea butterfly.

Which do you like best pteropods or sea butterflies?

Which do you imagine you'd like most to see

What do you think now?

Sea butterflies or pteropods mostly eat algae, and they range in size from a lentil to an orange. This doesn't sound too threatening until you discover that they trap the algae in a sticky web. 

Sea butterflies/pteropods live near the surface of the water of all the seas. The 'wings' (which are really, unromantically, a modified foot) flap to propel the thing along just like real wings.

Most pteropods/sea butterflies don't have a shell, and if they do it's very small and thin.

I'm afraid they're molluscs, like an octopuses or a slugs.

So, now what? Sea butterfly or pteropod?

Well, it might depend on who you are.

I'd imagine a male-female bias if I dared...

...but I don't.
