Peckoltia greedoi is a newly-classified species of suckermouth armored catfish found in the Gurupi River of Brazil. Jonathan W. Armbruster, David C. Werneke, and Milton Tan, who are researchers at Auburn University in Alabama, named it after Greedo, a character from Star Wars. Greedo is best remembered as a bounty hunter who cornered Han Solo on Tatooine. Solo quite properly shot him at the first opportunity.
The resemblance is obvious, so I would advise shooting first upon encountering such a fish.
