Way of life
The spider crab moves relatively little
and fastens amongst other things, algae on its carapace so that is not
seen. It has small hooks on its carapace that enable it to attach for
example bits of algae and sponges with its claw. If the crab changes its
environment, it changes its camoflage.
What they eat
The spider crab has a varied diet, but
starfish rays are popular, which became detached when the spider crab
holds onto them.
