Justin Bieber's Bronx beaver isn't alone
Surely there must be more.
Continuing right along that biological thread, Freddy Mercury will be forever remembered for being prodigiously mustachioed, supremely dramatic, and...an isopod (not a trilobite techinically!). Cirolana mercuryi (they append the "i" so you know it's smart) isn't much to look at sure, but neither was Freddy and look at all he accomplished.
The undisputed champ of species honorifics must certainly be Frank Zappa, with not only two (not quite boring) species named after him, but also an entire genus of animals! First up: his jellyfish, Phialella zappai. An italian biologist wanted to met Zappa, so this was his gambit (it paid off, they became semi-friends for a long while after). Next: his spider, Pachygnatha zappa, after the striking mustache-looking creepy things on its face. And finally, the entire superset of animals, simply called Zappa. It's a genus of adorable little mudskippers that Zappa "won" for his vehement defense of the First Amendment (I don't see Tipper Gore getting too many animals named after her).
Let that be a lesson to you, Justin Bieber. True immortality comes not from a single animal, but an entire species of little sycophants all chattering about being backstage when the shit hit the fan.
