Behavior
Migrations generally take place in autumn, with some crabs covering over 100 miles in eight months. All crabs are vulnerable to predation when moulting, and ''M. squinado'' becomes gregarious around that time, presumably for defense against predators. Females can produce up to four broods per year.Food
''M. squinado'' feeds on a great variety of organisms, with seaweeds and molluscs dominating in winter, and echinoderms such as sea urchins and sea cucumbers in summer.References:
