Oceanic Manta Ray

About Oceanic Manta Ray

The oceanic manta ray is the largest ray in the world, reaching wingspans of up to 7 metres. Unlike their reef-dwelling cousins, oceanic mantas roam the open ocean and are often encountered at remote offshore seamounts and islands. They are typically darker in colour and can dive to depths exceeding 1,000 metres. Their populations are declining due to targeted fishing for their gill rakers.

Quick Facts

• Habitat: Open ocean (pelagic), visiting offshore seamounts, oceanic islands, and cleaning stations

Fun Facts

Oceanic mantas are the largest rays on Earth, with wingspans exceeding 7 metres,They have been tracked migrating over 1,100 km across open ocean,Females give birth to a single pup after 12-13 months of gestation,A single oceanic manta is worth an estimated $1 million in dive tourism over its lifetime versus $500 dead

Diving Tips

Oceanic mantas are less predictable than reef mantas. At Socorro, they often approach divers closely — remain still on rocky substrate and they may hover directly above you. Never chase or touch them.
