Do you know that Female sharks have thicker skins than males?

The skin of Female sharks is thicker than that of male sharks. Scientists believe it’s because males have a strange proclivity for biting females during mating. Despite this, sharks may congregate in great numbers. More than 10,000 blacktip sharks were spotted off the coast of Florida in February 2016, according to researchers. Pregnant female sharks, on the other hand, appear to avoid males on migration routes.

Covered with millions of tiny modified teeth called dermal denticles, shark skin is incredibly tough, especially on females. In fact, some female sharks have skin twice as thick as their male counterparts. This ensures little damage is done during the mating process, since males must bite the female’s back, flanks and fins to get into the proper mating position. While these bites are less vicious than feeding bites, they can still inflict wounds.
