[00:00:00]This predator bites once, then follows you for days waiting for you to die. The Komodo dragon, over 3 m long, over 100 kg, the largest [music] lizard on Earth.

[00:00:11]For decades, scientists believed it killed prey with [music] bacteria-filled saliva. They were wrong. In 2009, researcher Brian Fry used MRI scans to reveal something no one expected: two complex venom glands hidden in the [music] Komodo dragon's lower jaw. The most structurally sophisticated venom system ever described in a reptile. When it bites, >> [music] >> 60 serrated teeth slash deep lacerations into the flesh. The venom enters through those wounds, [music] releasing toxins that inhibit blood clotting, drop blood pressure, and induce shock. [music] But here's what makes this predator terrifying: its bite force is surprisingly weak for its size. [music] It doesn't crush, it grips and rips. One savage bite, then it releases the prey.

[00:00:58][music] The victim may escape, but the bleeding won't stop. Energy drains, the body weakens, >> [music] >> and the Komodo dragon simply follows, calmly, patiently, sometimes for days, until [music] the prey collapses. No chase, no wasted energy, just time working in the dragon's favor. Most [music] predators kill with speed. This one kills with patience. One bite [music] decides the outcome. Everything after is just waiting. Follow for more predators that hunt in ways you'd never expect.
