Mantas may live up to 25 years or so...

Mantas have about 300 rows of tiny, peg-like teeth, each about the size of the head of a pin.

giant manta (Manta birostris), is the largest of the rays, with the largest known specimen having been nearly 13ft across its pectoral fins (or "wings") and weighed in at 3,000 kg (6,600 lb).

The Manta ray's mouth is big enough to fit 4 full grown men through it at once.

The largest reported in the scientific literature measured 22 feet (6.7 metres) across and there is one report of an individual 30 feet (9.1 metres) across. But most Mantas encountered by people are about 12 feet (4 metres) across.

Divers have observed Mantas as deep as 100 feet (30 metres), but no one knows how deep they can swim.
