Manta Rays.... Holly fucking shit. This guy blows my mind.

Manta, a genus within the elasmobranchii subclass that is shared with cartilaginous fish such as sharks and sting rays. Manta rays are one of the larges animal within the subclass, alongside the gigantic whale sharks and the derpy looking basking shark. The largest measured manta ray is a Griant Oceanic Manta Ray (Manta birostris) that was 9 meters long. THATS A THREE FLOOR HOUSE!!. Imagine swimming next to that thing. They average around over a tonne! They have the largest brain to body weight ratio of any species of fish that we know today. 

Though they are in the same order as sting rays, they have NO STING! They are essentially harmless. Manta rays, despite their gigantic size, they mainly feed on plankton. They spend hours feeding to consume around 30 kgs of food a day. 

 Manta Rays are awesome ><
