Cryptopal David Pescovitz posts today at Boing Boing about the new "Batman fish":

The Otocinclus batmani is a newly-discovered species of catfish that’s named after comix hero Batman. Ichthyologist Pablo Lehmann, of the Pontificia Universidade Catolica do Rio Grande do Sul, named the fish based on a bat symbol-like spot on its tail. The fish, around 4cm long, was discovered in Colombia and Peru.
