In Which Tan Is All Of Us And Manny Is Not Ready To Accept The Truth.

— Neil Gaiman, Coraline

Swimming with a 16feet ( 5meters) oceanic manta ray     

Giant manta rays are the largest rays in the world with wingspans up to 29 feet (8.8 m) wide and weights up to 5,300 pounds (2,404 kg).

Giant manta rays have the biggest brains of any fish studied so far. They use that brain power to learn, exercise their memory, distinguish between objects and even recognize themselves in the mirror.
