Between shark and ray: The evolutionary advantage of the sea angels

Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialised, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes.
