Quick answer
The manta ray is a huge but harmless filter-feeding fish related to sharks, with a wingspan that can reach 7 meters (23 ft). It glides through the open ocean by flapping its broad pectoral fins like wings and feeds by funneling tiny plankton into its mouth. Mantas have the largest brain of any fish and are curious, intelligent animals that pose no danger to people.

Biology
Manta Ray (Mobula birostris) is classified as Fish with conservation status Endangered. Typical weight Up to 1,400 kg (3,000 lb); lifespan around Up to 40 years or more.
Ecology
Diet: Filter feeder (plankton). Habitat: Tropical and subtropical open ocean. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Behavior and intelligence
Manta rays are graceful, curious animals that often approach divers and may circle them repeatedly. They have the largest brain-to-body ratio of any fish and have passed mirror tests that suggest a high level of awareness. Mantas sometimes leap clear of the water, though scientists are still unsure exactly why.
Filter feeding
Despite their size, manta rays eat some of the smallest food in the ocean. They swim with their mouths open, channeling water and plankton between flexible head fins called cephalic lobes, then strain out tiny shrimp and fish larvae with comb-like gill plates. Large groups sometimes gather where plankton is abundant.
Habitat and range
Manta rays live in warm tropical and subtropical waters around the world, often near reefs, seamounts, and coastlines where they visit cleaning stations to have parasites removed by smaller fish. They are strong swimmers that can travel long distances across the open ocean in search of food.
Conservation
The giant manta ray is listed as Endangered. Slow to reproduce, with females giving birth to a single pup every few years, mantas recover poorly from population losses. They are threatened by targeted and accidental fishing, especially demand for their gill plates, as well as boat strikes and entanglement.
Research notes
Figures for manta rays (Mobula birostris) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter manta rays in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Endangered) when discussing conservation.
