[music playing] NARRATOR: The submersible has now reached a depth of 500 meters. This is where they're hoping to find their colossal squid. MAN: Whoa.
Whoa what-- Oh, that's a stygiomedusa. NARRATOR: Kat has spotted something else in the darkness. [music playing] Wow.
NARRATOR: They're the arms of a giant jellyfish, easily 10 meters long. [music playing] They hang from a bell-shaped body. [music playing] This is stygiomedusa gigantea, thought to be one of the largest invertebrate predators in the deep sea.
[music playing] Drfting alongside the submersible, it's clear just how big it really is. [music playing] Few people have ever seen this spectacular creature alive, so we know very little about it. [music playing] The broad ribbon-like arms don't have stings, and no one knows just how they're used to catch prey.
[music playing] It could be that the long streaming drapes simply entangle or wrap around their victims. [music playing] It's a great thrill to have had such an intimate encounter with one of the Antarctic's most elusive giants. [music playing] KAT: It was out of this world.
It's full of stranger things than most people can imagine. Down there, the truth really is stranger than fiction.
