Dermal denticles on a Dogfish shark {Scyliorhinus sp}. These tooth-like structures on the skin of sharks and rays afford protection from predators and ectoparasites. They are also speculated to reduce drag whilst swimming. False-colour scanning electron micrograph (SEM) x56 magnification when image printed 10cm across.
