Oceanic Manta Ray

Môi trường sống: Open ocean, oceanic islands, and seamounts; visits shallow cleaning stations and surface plankton slicks, with tagged dives far deeper

Phạm vi phân bố: Circumglobal in tropical and warm temperate oceans, concentrating seasonally at offshore islands — the Revillagigedos, Raja Ampat's deeper stations, Ecuador and Peru, Mozambique, and mid-ocean ridges

Hành vi: Where reef mantas commute, oceanics wander — crossing basins between seamounts and boiling upwellings. Around divers at Socorro they are famously interactive, banking to hold a diver in view, hovering in bubble streams, and returning repeatedly over a full dive; whether they seek the sensation or the inspection, the choice is visibly theirs.

Chế độ ăn: Zooplankton filtered on long open-water feeding runs and at productive upwellings

Kích thước: thường vào khoảng 4.5 m; ghi nhận đến độ sâu 7.0 m (disc width; the largest ray on Earth).

Hold still and let the manta pilot the encounter, keep off cleaning stations, never touch — the mucus layer protects them — and avoid chasing when one breaks away; at Socorro, guides brief a no-bubbles-directly-beneath courtesy that many mantas ignore on purpose.

Endangered since 2020, driven by targeted gill-plate fisheries and bycatch; protected under CITES and CMS, with sanctuaries in Mexico, Indonesia, and elsewhere doing measurable good.
