00:00 A miniature marine killer.
00:02 Jellyfish are among the deadliest predators in the oceans.
00:11 Some have enough venom to kill a human being in a few minutes.
00:16 But they also have their own problems to deal with.
00:19 Off the coast of North America, in the middle of the Pacific Ocean, we discover a strange universe.
00:27 A 45-meter-high Varek forest rises from the seabed.
00:33 A sleeping army is waiting for their turn.
00:42 A huge colony is about to invade the coast.
00:47 They are no bigger than a grain of rice.
00:50 Jellyfish polyps.
00:55 Nobody knows what to expect.
01:03 And this can last for years.
01:05 But this summer, millions of them will mutate at the same time.
01:10 We see tentacles appear.
01:15 Then, the prey.
01:19 And then, the prey.
01:23 And then, the prey.
01:27 And then, the prey.
01:32 Then, the jellyfish larvae detach.
01:35 We have just witnessed the birth of a Chrysaora, a miniature marine killer.

02:23 In the space of a few months, the jellyfish have seen their size of departure multiplied by 100.
02:29 They drag behind them, 5-meter-long urtic tentacles.

02:53 But this giant jellyfish has a microscopic enemy living in the Varek forest.

03:14 The amphipode, a carnivore similar to a shrimp, is no bigger than a flea.
03:38 An amphipode attack can kill a jellyfish in a few days.
03:42 But the rescue is on its way.
03:49 A second hitchhiker takes the lead.
03:54 For the crab, it's as simple as picking a fruit on the branch.

04:09 For the jellyfish, these crabs are a real close-up.
