Gruesome video footage reveals what one scientist is calling the discovery of “freshwater killer whales,” according to Discover Magazine’s “Not Exactly Rocket Science” blog.
Discover’s Ed Young writes that Julien Cucherousset from Paul Sabatier University in Toulouse, the researcher who coined the term “freshwater killer whales,” spotted the European catfish feeding on pigeons after local fisherman alerted him to their unique behavior. Mr. Cucherousset filmed the catfish from a bridge overlooking the island where the pigeons were cleaning themselves.
