The Mackled Malaclaw is a land creature that has a close resemblance to a lobster. The Malaclaw has light grey skin with green spots, and can reach a length of twelve inches. Despite the fact that it has a resemblance to a lobster, it is unfit to eat, and anyone who does eat the flesh of a Malaclaw will come down with a nasty fever and develop a green rash.

The Malaclaw is found along the rocky coastline of Europe and dines mainly on crustaceans. A bite from a Malaclaw has the unusual side effect of making the victim unlucky for up to a week. Any witch or wizard bitten by a Malaclaw should call off all bets, wagers and ventures since they will definitely go against them.

It is theoretically possible for Felix Felicis to serve as an antidote, though regularly consuming the potion for a full week could cause other side effects.
