...which exposes their feeding grounds – seaweed-covered rocks, 100 metres from the shore. Getting there is a race against the tide.

01:01

Speaker A

They leap from rock to rock. These crabs seem to be afraid of the water.

01:33

Speaker A

And for good reason. A moray eel. The chain moray is a specialist crab-hunter. Its blunt teeth can easily grip and crush a crab shell.

02:11

Speaker A

It's the crabs' deadliest enemy. But the crabs' feeding grounds are still a long way off.

02:34

Speaker A

They must press on. Halfway. But their enemy has other ideas. Crossing the land to reset the ambush.

03:28

Speaker A

To feed, the crabs must keep going. But nowhere is safe. An octopus. Also a crab killer.

04:12

Speaker A

The crabs make a dash for it. Made it! Risking life and limb to graze on these seaweed pastures.

05:00

Speaker A

But in two hours' time, when the tide starts to turn, they will have to run the gauntlet all over again.
