4. Size matters in the hammerhead world. You’ve got the little guys, measuring up to a mere meter, and then there are the true giants, stretching beyond 6 meters. That’s quite the range, and their weight reflects it too, tipping the scales anywhere from 5 to a whopping 500 kilograms.

5. Meet the smallest of the hammerhead crew – the small-headed hammerhead shark or shovelnose shark. It doesn’t stretch much beyond a meter and weighs in at around 10 kilograms.

6. On the flip side, we’ve got the heavyweight champion – the giant hammerhead shark. This bad boy can grow up to a colossal 6 meters and weigh an impressive half a tonne. Now that’s a big fish in a big pond!

8. Hammerhead sharks are globe-trotters, but there’s one place they don’t fancy – the chilly Arctic Ocean. They’re all about those warm waters, cruising around in the toasty zones of low and temperate latitudes. And when summer hits, they might even venture a bit closer to the poles for a change of scenery.

9. Guess who’s a regular in the Mediterranean Sea? The common hammerhead shark! It’s not shy about making appearances and, believe it or not, might even take a detour into the Black Sea from time to time. Talk about a well-traveled fish!


10. Time isn’t always on the side of hammerhead sharks. On average, these ocean wanderers enjoy a decent 20 to 30 years of underwater adventures. But, surprise, surprise – some of them manage to pull off an impressive half-century, living up to a ripe old age of 50. Talk about making waves for a good, long while!

Eating habits

11. Brace yourself for some serious ocean drama because all members of the hammerhead shark family are known for their wild aggressiveness.

13. Hungry, hungry hammerheads! These sharks have a serious need for speed when it comes to metabolism, making them perpetual snack-seekers. Their constant hunger doesn’t just make them a threat to other sea creatures; it puts humans on the caution list too. It’s like they’re always up for a bite!

Intelligence and Social Behavior

14. The giant hammerhead shark is a bit of a lone wolf in nature. But here’s the twist – the rest of the hammerhead crew prefers a solo hunting session at night. Come daytime, they’re all about the squad life, gathering in massive packs. There’s even this wild story off the coast of California, where the common hammerhead sharks threw a party with a guest list of about 1000 strong. Talk about a fin-tastic fiesta!


15. When it comes to family planning, the hammerhead shark knows how to keep the family bustling. They’re all about live births, and boy, are they prolific! Every year, mama hammerhead brings around 10 little sharks into the world. But hold on to your fins, because the giant hammerhead shark takes it to the next level, popping out a whopping 40 adorable shark pups in one go. Now, that’s what we call a fin-tastic family reunion!


16. Picture this: in Southeast Asia, the meat and fins of the hammerhead shark are treated like a delicacy, turning these amazing creatures into sought-after treats. Unfortunately, this appetite for hammerhead goodness has taken a toll, and their population is on a steady decline. To put the brakes on this concerning trend, hunting these fantastic sharks is now a no-go for three out of the nine species as they’re officially labeled as vulnerable. It’s a step towards protecting these underwater wonders and keeping the oceans thriving.
