Manta rays and stingrays differ in size, diet and appearance. Manta rays are significantly larger than the stingrays, with oceanic mantas reaching a size of 23 feet from wing tip to wing tip, and reef mantas, a smaller species, reaching a wing span of 9 to 15 feet. Larger stingrays grow to 6.5 feet in length. The manta ray also lacks the characteristic venomous stinger found on the stingray's tail.
