Introduction to the Chondrichthyes

  • MP Berkeley's introduction to the cartilaginous fish, including sharks.
    Introduction to the Chondrichthyes Jaws Sharks, skates, rays, and even stranger fish make up the Chondrichthyes, or "cartilaginous fish." First appearing on Earth almost 450 million years ago, cartilaginous fish today include both fearsome predators and harmless mollusc-eaters (harmless, that is, unless you are a mollusc)
  • . A number of shark and ray species are fished, commercially or for sport
  • . Thus, preservation of the whole body of a cartilaginous fish only takes place under special conditions
  • . This complete fossil rhinobatoid (guitarfish -- one of the earliest rays), Rhinobatis , shown on display at the Senckenberg Museum in Frankfurt, Germany, is from the Upper Cretaceous of Haqel, Lebanon, a place that has yielded many complete fossil sharks and rays
  • . UCMP Special Exhibit: Former UCMP graduate student has worked extensively with living great white sharks, as well as with fossil sharks and fish
