Its large and flat head offers it perfect stability. It is distinguished from other hammerhead sharks by the large size of its dorsal fin. Its grey-colored body is massive.

The great hammerhead shark can be found in most tropical oceans, in the Red Sea and the Mediterranean.

There really is something inexplicable with that shark, as if time stopped in its presence. The great hammerhead shark feeds on bony fish, rays, smaller sharks and occasionally crustaceans and cephalopods. It can live up to 35 years old. This dangerous predator owns a veritable arsenal of chomping power :

  • Two jaws marked by numerous razor-sharp teeth
  • A well-developed electromagnetic sensitivity to detect any hidden prey
  • A streamlined body for speed and agility
  • A body immune to the ray’s venom (its favorite prey)

We just know that after a gestation period of 10 month females give birth to approximately 40 little sharks of about 60cm. It should be noted, nevertheless, that a hammerhead shark has already given birth without mating with a male (parthenogenesis). This auto-reproduction happened in a zoo in USA.

    Each year in summer, we can asset to a large migration of hammerhead sharks somewhere next to the coasts of Malaysia … still a mystery to man. Victim of overfishing, this shark is a protected species since March, 2013.

    In French Polynesia, you have a better chance to encounter the great hammerhead shark in the Tuamotu archipelago. You could cross its path during your dives in the passes of Fakarava and Rangiroa, especially in the Garuae pass where it became the master of the place. A really breathtaking encounter!!
