The Sally Lightfoot crab (Graspus graspus) is rumored to have been named after a Caribbean dancer, because they are agile and fast. They can only eat during low tide, when seaweed is exposed on the rocks offshore. That means every day they need to travel out to those rocks. They are indeed light-footed, leaping from rock to rock to get to their feeding grounds. Why don’t they just swim? Because moray eels and octopuses are waiting for the daily pilgrimage. These predators will even leave the water to chase down a tasty crab dinner! Nature is brutal.

It’s a treat any time we can watch a nature documentary narrated by Sir David Attenborough. This segment is from the BBC TV series Blue Planet II. It’s not only beautiful and informative, but quite dramatic as we follow a crab on the dangerous route to his daily feast. -via Born in Space
