Hey science fans! Did you know that Venezuela is one of the most bio-diverse countries in the world? You can find animals there that live nowhere else.
Ichthyologists Francisco Provenzano from Universidad Central de Venezuela and Scott Schaefer of the American Museum of Natural History have found a previously unknown species of climbing catfish. Lithogenes wahari appears to be an evolutionary marvel.
One fish was discovered in a remote region of Venezuela’s Amazonas state nearly 20 years ago, but good and plentiful specimens weren’t found until recently. The catfish was eventually found in large numbers in the Cuao River, a tributary of the Orinoco.
The fish are bony and armored, have a “specialized pelvic fin” and a “grasping mouth” that allow them to climb onto rocks in a locomotion similar to that of an inchworm. Lithogenes wahari evolved to adapt to rapidly changing water levels in the Venezuelan Amazon.
