Thanks for the explanation, Joe! Nice to know my latin roots are still vaguely (very vaguely) there!
Did I read that you actually named the sponge? The only traces I can find of it are on a website 'Old as the Hills' and a PDF that is partly in Oriental characters. I should be processing images but curiosoity got the better of me ;) I must 'waste' quite a lot of time trying to learn and find out about various things that are new to me!!
I suppose that there are quite a few organisms still being catologued and, unfortunately, quite a few that may never be - especially in rain forests.
There's a link broken on that site's page about Stenodema laevigata. Look at the third paragraph's link titled 'S. calcarata' - it's trying to load a page from your hard-drive. An easy mistake to make, done it myself a thousand times! Feel free to delete this VM after.
I've been trying, without success to translate your latin name. I've got about as far as 'sharp youth' or 'clever boy' from acutis and puer but being a dumbo at latin grammar I'm not sure - go on... tell all!!
