Climbing Fish

As per ScienceDaily, a new species of fish from tropical South America is confirming suspected roots to the loricariid catfish family tree. Lithogenes wahari shares traits with two different families of fish: the bony armor that protects its head and tail, and a grasping pelvic fin that allows it to climb vertical surfaces.

The discovery of both of these characteristics in Lithogenes suggests to ichthyologists Scott Schaefer of the American Museum of Natural History and Francisco Provenzano of the Universidad Central de Venezuela that the common ancestor of the Loricariidae and Astroblepidae probably could grasp and climb rocks with its tail and mouth.

It took years to pin down where the fish was found, but the team collected L. wahari after several trips further and further into the headwaters of the Río Cuao, a tributary of the Río Orinoco. They literally picked 84 specimens off of rocks.

Well, this is how it looks... Not so pleasant but interesting!
