Comparative morphology of labial cartilages in sharks

Comparative morphology of labial cartilages in sharks (Chondrichthyes, Elasmobranchii) C. Klimpfinger & J. Kriwet ABSTRACT: During the last years, feeding mechanisms of sharks have been documented mainly based on their stomach contents supplemented by video footages of feeding behaviours in some species. Rare kinematic analyses of shark jaws contributed additionally to our knowledge. However, not
