We’ve had some great posts on Fishbase and fish eyes recently, thanks to Carl and Lars. Most of the lab is working on abstracts for SICB 2012, so let’s get back to some fish videos.
This week’s contender is Petenia splendida, a fish-eating cichlid from Central America. If you saw one of this in a fish store, it would probably be called a “red bay snook”. The name isn’t particularly accurate: the fish is rarely red, doesn’t live in a bay, and isn’t a snook.
What this fish does have, though, is an impressive set of jaws for capturing prey. Petenia splendida is an impressive piscivore (fish-eater) that has some of the most protrusible jaws of any cichlid.
