FAQ
Frequently Asked Questions
No, it is a type of ray, although its elongated body can cause confusion. It is in the same subclass (Elasmobranchii) as sharks and rays.
It uses the rostrum to slash at schools of fish to injure prey, to dig in sediment for buried animals, and for defense.
They are not aggressive towards humans but can inflict serious injury with their rostrum if provoked or accidentally encountered.
Primary threats include habitat loss, entanglement in fishing gear (bycatch), and historical hunting for their rostrums, fins, and meat.
