New species of "jaguar catfish"

Remember the film The Life Aquatic, with its man-killing "jaguar shark?" Well, that does not exist, but we do have jaguar catfish showing patterns like the big cat. The newest species comes from the Amazon, where is has been christened Stenolicnus ix - "ix" being a Mayan term describing a jaguar. OK, there were no Mayans in South America, but it's a cool choice anyway.
