Description
The largest ray in the world. It differs from the reef manta in its black-and-white T-shaped shoulder markings, dark spotting confined to the belly centre, a dark mouth and a grey-edged belly. It spends more time in the open ocean, diving deep and visiting coastal reefs and upwellings to feed and be cleaned. Like the reef manta it has a very low reproductive rate.
In the Maldives
Much rarer than the reef manta in the Maldives; most sightings come from the south, notably Fuvahmulah, and researchers have now photo-identified more than 1,000 individuals in Maldivian waters. Protected with all rays since 2014.
