denticle

Identifying this structure was compelling evidence that the teeth on the tenaculum really are teeth and not leftover denticles.

Recirculation patterns, highest velocity and vorticity developed directly on top of the denticles and in spaces between the denticles.

This may have been because reef mantas have smaller dermal denticles and so there was less friction to keep the cups in place.

They analyzed the fossils’ rostral denticles, the spikes that jut from the sides of a sawfish’s snout to aid in foraging and self-defense.

I wanted to reach out and touch its back, which was covered in denticles, V-shaped scales that were like teeth all over the shark’s body.
