From escience News (August 17, 2011), we learn learn, “Scientists discover the most primitive living eel”: Protoanguilla palau. Off Palau.
“The equivalent of this primitive eel, in fishes, has perhaps not been seen since the discovery of the coelacanth in the late 1930s,” said Dave Johnson, ichthyologist at the Smithsonian’s National Museum of Natural History and lead author of the team’s research. “We believe that such a long, independent evolutionary history, dating back to the early Mesozoic (about 200 million years ago), retention of several primitive anatomical features and apparently restricted distribution, warrant its recognition as a living fossil.”
