The Google blog just made a post bragging about its success with Google Earth, it's been helpful for ant researchers as of lately. So helpful that they named a new ant species after them - Proceratium Google. (wiki link)

Proceratium Google

Another notable animal species with a company name is the GoldenPalace.com Monkey (Callicebus aureipalatii), whose name was auctioned out to raise money for the research and preservation of the species.

I also remember something about naming a newly found bacteria in the baltic sea after the Tamagotchi, couldn't find any links, though...

UPDATE: Oh, look, I'm on slashdot
