Manta ray

Manta rays are a members-only fish that require a Cooking level of 91 to cook. 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.

They are rarely used as food due to the high burn rate and the existence of other foods that heal close to the same amount, but are easier to obtain.

Manta rays heal 200 to 2275 life points depending on your Constitution level.
