The Largest Hammerhead Shark Ever Recorded

[00:00:00]The largest hammerhead shark ever reliably [music] measured was an absolute giant. A female great hammerhead reached about 20 [music] ft long and weighed roughly 1,280 lb. That is longer than many cars and heavier than a grand piano. But here is the crazy part. This record-breaking [music] shark was a pregnant female caught off Florida in 2006. Scientists believe even larger great hammerheads may [music] have existed, but very few reach these incredible sizes because great hammerheads are naturally [music] rare at older ages. Imagine looking into the ocean and seeing a shark with a head wider than some [music] people are tall.

[00:00:34]Meet the great hammerhead, the largest hammerhead species on Earth and one of the ocean's most specialized predators.

[00:00:39][music] That bizarre hammer-shaped head is called a cephalofoil, and it is far more than an odd design. Spread across it are thousands [music] of tiny sensory organs called the ampullae of Lorenzini. These organs allow the shark to detect [music] weak electrical fields produced by other animals. That means a stingray can bury itself completely beneath [music] the sand and still have nowhere to hide. The hammerhead can sense its heartbeat and muscle movements like a living underwater [music] detector. Great hammerheads are also master hunters.

[00:01:08]Researchers have observed them [music] pinning stingrays to the seafloor with their massive heads before delivering a bite. Some scientists have even documented them eating stingrays whole, including [music] the barbs. Their eyesight is incredible, too. With eyes positioned on the far ends of their hammer-shaped heads, they have one of the widest [music] fields of view of any shark, helping them scan more of the ocean at once. And here is a knowledge bomb. Despite their intimidating [music] appearance, there has never been a single confirmed fatal hammerhead shark attack on a human in recorded history.

[00:01:39]Across all hammerhead species, only a tiny number [music] of unprovoked bites have ever been documented over centuries. Great hammerheads are powerful swimmers, too. Some individuals [music] have been recorded traveling hundreds of miles through open ocean in search of food and warmer waters. Yet these ocean [music] giants face a much greater threat from us than we do from them. Great hammerhead populations have declined significantly [music] in many regions because of overfishing and accidental capture. Today, the species [music] is classified as critically endangered by conservation organizations. The next time someone says all sharks are mindless [music] predators, remember this. The largest hammerhead ever recorded was not just enormous, it was one of the most advanced hunters in [music] the ocean equipped with sensors that almost seem like a superpower.
