Deep Sea 3D

00:02:49 These are not visitors from an alien planet.

00:04:08 Neither plant nor coral...

00:05:08 He hides from predators by looking like a sponge.

00:06:28 The balance between predator and prey is always shifting.

00:07:20 But the snail is immune.

00:08:14 ...removing and eating parasites.

00:09:21 ...they somehow manage to find this special spot.

00:11:21 ...where they are stunned and consumed.

00:12:59 Ocean currents can sweep entire kelp forests...

00:14:25 ...they sweep nutrients up from the depths to nourish a dense growth of plankton.

00:15:33 ...then slowly squeeze out all but the food.

00:18:26 But there's a predator who covets those stingers.

00:20:07 The Irish lord.

00:39:06 ...is linked to theirs.
