Get to know the great spider crab

The great spider crab's carapace is pear-shaped and can be up to 9 cm in length. The great spider crab is somewhat more slender compared to the ordinary green crab.

Decorates itself

The great spider crab is slow and it cannot use its claws. Therefore it hides itself using camouflage. It pastes small algae and bits of sponge onto its carapace and legs using a mucus like mouth secretion.

Meet a great spider crab

The great spider crab is found throughout most of Denmark. You can encounter it while snorkelling across a sandy bottom or rocky bottom with seaweed. But you'll have to keep your eyes open. The great spider crab is shy and hides itself from view.
