📌Onchopristis Numidus
Onchopristis, or “giant saw”, is a genus of extinct giant sawskate that lived during the Upper Cretaceous in what is now North Africa. It had a long, hard, shovel-shaped snout called a rostrum. The saw-like rostrum, lined on both sides with modified tooth-like structures with hooks and barbs called denticles. Onchopristis used its intimidating, 2-meter long rostrum to unearth crustaceans at the bottom of shallow waters like sawfish do today.
With the modern sawfish, the rostrum is covered with electrosensitive pores that allow the sawfish to detect slight movements of prey hiding in the muddy sea floor. The rostrum also serves as a digging tool. Should suitable prey try to swim past, the normally lethargic sawfish springs from the bottom and slashes at it with its saw. Sawfish also defend themselves with their rostrum against intruding predators such as sharks.
