Manta rays are a members-only fish that require a Cooking level of 91 to cook and give 216.3 Cooking experience when cooked. Burning a manta ray results in a burnt manta ray. These maintain a significant burn rate even when cooked by players with level 99 Cooking and cooking gauntlets, with an approximate 23% burn rate at level 99 Cooking. Using the Cooking cape will prevent players burning manta rays.
Manta rays heal 22 hitpoints in one serving and are considered to be among the best foods in the game. They weigh less than tuna potatoes (0.5 kg), yet more than dark crabs (0.3 kg), which both also heal 22 hitpoints in a single serving.
