The Parasite That Wears Its Host Like a Suit

追加: 2026-05-23

[00:00:00]Scientists just discovered a creature that doesn't just kill its host, it hollows it out from the inside and then wears its body like a mobile apartment while raising its babies. Meet the pram bug, a transparent amphipod about the size of your fist living nearly 13,500 ft below the ocean's surface in Antarctica's Weddell Sea.

[00:00:19]This thing is absolutely terrifying.

[00:00:22]It hunts down jellyfish and salps, those barrel-shaped gelatinous creatures floating through the deep, and burrows inside them while they're still alive.

[00:00:30]Then it systematically eats them from the inside out, gutting the entire body while the host organism is conscious and helpless.

[00:00:37]Once the host is completely hollowed out, the pram bug climbs into the empty translucent husk like it's putting on a suit of armor, but [music] here's where it gets wilder.

[00:00:46]The bug doesn't just live in there, it uses the corpse as a mobile nursery for its eggs. It grabs the rim of the barrel with its own legs and propels the whole thing through the crushing darkness of the deep ocean, >> [music] >> keeping its developing offspring safe inside this borrowed corpse home.

[00:01:02]Evolution designed the perfect parasite.
