Yet another "Creationist's Nightmare"
A previously unknown species of climbing catfish has been discovered in remote Venezuela, and its strange traits are shaking the evolutionary tree for these fish.
The newfound catfish, Lithogenes wahari, shares traits with two different families of fish - Loricariidae (armored catfishes) and Astroblepidae (climbing catfishes). It has bony armor that protects its head and tail, and a grasping pelvic fin that helps it to climb vertical surfaces such as rocks.
These characteristics in L. wahari suggest to ichthyologists Scott Schaefer of the American Museum of Natural History in New York 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. Fish in both families, as well as the new catfish, have sucker mouths.
The unusual catfish caught the team's attention 20 years ago in Caracas. An anthropologist, Stanford Zent of the Instituto Venezolano de Investigaciones Cientificas, working in the remote state of Amazonas collected samples of local foods and brought them to the Instituto de Zoologíca for identification.
"The fish was so strange in morphology that it did not fit into any taxonomic category that we were aware of," Schaefer said. "But it looked like it was run over by a truck. We needed better specimens."
There are so many "Creationist Buster" species out there in the public eye now, I just don't understand how anybody could reasonably lose an argument with a creationist.
