Darrel:
If you want more snake names (at risk of setting up a pattern that you won't easily be able to break free from later?), you might try . . .
CROTALUS (Genus name of the rattlesnakes.)
BASILISK (Mythical king of the serpents.)
A quick perusal of the glossary of Bulfinch's Mythology yielded the following, which are cool sounding names and probably esoteric enough to pass a trademark search:
ALECTO ("Literally, she who rests not. One of the Furies. She was sent by Juno to stir up discord among the Trojans")
ARGUS ("100-eyed guardian of Io, who was killed by Mercury.")
CORTANA ("In the legends of Charlemagne, the name of Ogier's sword.")
HYDRA (A nine-headed monster; one of the labors of Hercules was to kill it.)
YAMA ("Hindu god of the infernal regions. He is the deification of the first mortal to die and reach the realm beyond.")
If you want to branch out into bird names, a personal favorite of mine is:
CASSOWARY (A large, flightless bird of New Guinea, reputedly quite agressive and able to kill a man with the sharp claws on its feet.)
Good luck to you and me both!
