00:00Meet the sperm whale, the deep-diving, squid-hunting legend of the ocean.
00:05Largest toothed predator on Earth, and it's not even close.
00:08That's as long as a school bus, and heavier than nine elephants combined.
00:12Their massive square head, it holds the largest brain of any animal on Earth, up to nine kilograms.
00:18That brain helps them dive over 3,000 meters deep, holding their breath for up to 90 minutes.
00:23Talk about deep thinkers.
00:24Down there, they hunt giant squid, echolocating with powerful clicks that are louder than a jet engine.
00:30So loud it can stun prey.
00:32They're also super social.
00:33Sperm whales live in matrilineal pods made up of moms, aunties, and calves.
00:37They even have unique dialects, like accents.
00:40But sperm whales do more than hunt.
00:42They help regulate carbon in the ocean.
00:43How?
00:44By feeding deep and pooping near the surface?
00:46Yes, really.
00:47They fertilize plankton, which absorbs carbon from the air.
00:50That makes them climate heroes, and vital to our oceans.
00:53But threats like plastic pollution, ship strikes, and sonar endanger these gentle giants.
00:58We need to protect them, because protecting them means protecting our planet.
01:01The sperm whale isn't just the king of the deep.
01:04It's a key player in Earth's survival game.
