I wanted to answer your question without derailing/hijacking betty's post so here goes.

Nope I am not a biologist.

When i moved out on my own I was given a stuffed rattlesnake as a "pet" since my apartment didnt allow pets. It became quite the conversation piece when people visited so I wanted to give it a "cool" name. in searching for a name I can across the latin name for rattlesnake - Crotalus Adamanteus. That sounded cool, so he was named Crotalus.

When i got into online gaming I needed a cool screen name. The snake sat on a shelf near my computer and things just sorta fell into place.

I still have the sname (13+ years later) but now he overlooks my tying table



Sorry that was long winded but i think it is cool when people recognize the screen name for its latin origin.
