On the plate

White, sweet, delicate meat. This is the crab behind American soft shells.

Avoid: Returning it to the water alive. It is invasive, and it is caught to be eaten.

It arrived in ballast water and now wrecks nets and shellfish farms across the Mediterranean. Several regions have organised its fishery and sale, so eating it has become a useful act.
