It is known to be partial to munching on jellyfish.How to identify
Spider crabs are very different to 'typical' crabs. Orangey brown in colour, the great spider crab has long spindly legs like a spider and a distinctive pear-shaped shell. It is smaller than the spiny spider crab, which has an oval and more visibly spiky shell.Distribution
