Manta ray

Manta rays are a members-only fish that require a Cooking level of 91 to cook. When consumed, manta rays restore 22 hitpoints. These maintain a significant burn rate even when cooked by players with level 99 Cooking and Cooking gauntlets. With 99 cooking and using cooking gauntlets, a player will still burn approximately 23% of the manta rays cooked. A player with a cooking skill cape equipped will burn no manta rays.

Manta rays heal 22 hitpoints in one serving and are considered to be among the best foods in RuneScape. 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.
