Manta Ray

The Manta Ray is the largest of the rays, with the largest known specimen having been more than 7.6 m (about 25 ft) across, with a weight of about 2,300 kg (about 5,000 lb).
Mantas have been given a variety of common names, including Atlantic manta, Pacific manta, devil fish, and just manta. Recent studies have suggested that what is called manta ray are at least two different species, one smaller local and one much larger and migratory
Koh Bon is one of the best dive sites in Asia for seeing Manta Rays with West Ridge being a particularly good spot for Manta Ray encounters whilst scuba diving.
