What are Manta Rays?

Manta Rays are one of the most iconic creatures of the deep ocean. They are a type of stingray with two species – the giant oceanic manta ray and the reef manta ray.

The giant oceanic manta can grow up to 7 meters in width, making them one of the largest fish on earth, while the reef manta is slightly smaller and has a wingspan of up to 5 meters.

Manta Rays are migratory species, meaning they travel across international waters, so they are protected by the Convention on Migratory Species.

Although they spend most of their time in open water, Mantas inhabit coral reefs and feed on various marine life.|

Their size makes them an impressive sight in the wild and a popular attraction for scuba divers worldwide.

Fun facts about Manta Rays include that they have no teeth or scales but instead have smooth skin that helps reduce drag while swimming through the water. They also feed mainly on plankton which they filter from the water with their mouths!

Manta rays are large, graceful creatures that inhabit the open ocean. They have a giant, triangular-shaped body and two large fins that look like wings, giving them their name. 

They can grow up to 7 meters in width and weigh up to 2,300 kilograms. They have dark spots on their back, which they use as camouflage in the sea’s dark depths. Manta rays also have two horn-like structures on their heads known as cephalic lobes, which they use to turn corners and easily maneuver through the water.

What characterizes these animals is their giant mouths with keratin jaw plates to filter food from the water around them. Although they look intimidating due to their size, manta rays are harmless gentle giants that pose no danger to humans or other animals in their habitat.

Predators and Prey

Manta rays are filter feeders, meaning they consume their food by filtering tiny organisms from the water. They feed primarily on zooplankton and other tiny organisms like shrimp and krill.

They have few natural predators in the wild due to their large size but are sometimes preyed upon by sharks, killer whales, and large fish like tuna. The largest predator of manta rays is humans, who often hunt them for their meat or gill rakers which are used in some traditional medicines or for decorative purposes.

In recent years manta ray populations worldwide have been decreasing due to overfishing and habitat destruction, making conservation efforts more critical than ever.

Reproduction and Lifespan

Manta ray reproduction is difficult to observe in the wild, as the mating ritual usually takes place far away from human eyes. The female usually releases a pup following closely behind her after a gestation period of 12 to 13 months. Manta rays reach sexual maturity at an estimated age between 5 and 8 years old.

Their lifespan in the wild can be up to 25 years, although some live much longer. They are solitary creatures that live independently but can also live in groups or pairs during mating season. Reproduction and growth rates vary depending on the species and habitat of manta rays. Still, they need to reproduce more quickly to sustain their population numbers when it comes to human activities such as overfishing and water pollution.

Conservation Status

The International Union for Conservation of Nature (IUCN) has recognized the manta ray as a vulnerable species. Their population has been declining due to overfishing and other human-caused disturbances, such as habitat destruction and entanglement in fishing gear. They are also considered vulnerable to climate change due to their sensitivity to temperature changes. 

Several countries have established protected areas and regulations to reduce fishing pressure on these animals and promote sustainable tourism involving manta ray encounters to help protect them.

In addition, researchers try better understand their migratory patterns and habitat preferences so that conservation efforts can be more effective. Although the situation is improving, there is still much work to be done to ensure manta rays’ survival in the future.

Manta Ray in Fishing and Cooking

In some parts of the world, people fish manta rays for their meat, a highly valued delicacy with a mild flavor. People cook it in various ways to create an exciting and tasty meal. When cooking manta rays, freshness is essential for a good taste. Grilling or baking are popular methods for cooking manta rays, but chefs make ceviche and sushi with the meat.

Scientific Classification and Ray Species

Manta rays are a species of fish belonging to the genus manta within the family Mobulidae. They are one of the largest species of ray.

Manta rays belong to the genus Mobula, but it used to be in its “manta” genus, which is now obsolete. Recent DNA analysis confirms that manta is a junior synonym of Mobula. It belongs to the Mobulidae family, which includes manta rays and devilfishes, large species that live in the open ocean.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Chondrichthyes
  • Order: Myliobatiformes
  • Family: Mobulidae
  • Genus: Mobula (previously Manta)

Manta Ray vs. Stingray


The difference between manta and stingrays is their shape, appearance, size, and danger. Both are cartilaginous fish, but they differ in many ways.

The most crucial difference is that manta rays are not dangerous and do not pose any harm or toxicity to humans. In contrast, stingrays are venomous and have a stinger that can pierce human skin and cause pain and injury, often when stepped on.

Manta rays have large triangular-shaped fins, which give them a distinctively broad appearance. Their bodies are flat and rounded, while their mouths are on the underside of their heads.

Stingrays have diamond or disc-shaped bodies with a flat bottom and a pointed top, and they also possess a long, slender tail with a venomous stinger. Unlike manta rays, the mouth of a stingray is at the front of its body.

Additionally, manta rays can grow up to 7 meters long and weigh over 2 tons, whereas the largest species of stingray only reach up to 3 meters in length and weigh less than 400 kgs. This size difference makes manta rays easier to spot at sea than stingrays.

Manta ray vs. Devil Ray

Manta- and devil rays are both types of rays that belong to the Myliobatiformes order. Still, the most distinct difference is their body shape: Manta rays have much larger bodies than devil rays. Also, manta rays feed mainly on plankton, while devil rays feed on small fish, crustaceans, and invertebrates.

Reef and Giant Manta Ray FAQ

Where to dive or swim with Manta Rays?

If you want to swim with manta rays, you need to find them where they live, in tropical and subtropical oceans worldwide, with their range extending from the Red Sea and South Africa on one side to Hawaii and Mexico on the other.

Of the two species of manta ray, the reef manta ray stays in shallow waters close to coral reefs, whereas the giant manta ray migrates between regions.
Popular spots for meeting these creatures are Mexico, Hawaii, Qatar, Australia, and Indonesia, and you might find diving and snorkeling tours in the tourist areas of these regions.

While swimming with manta rays is an incredible experience, please remember to maintain a respectful distance so as not to disturb them or cause unnecessary distress. Seeing this creature is one of the divers’ and snorkelers’ most thrilling underwater activities.

Are manta rays dangerous, and can they kill or hurt humans?

Manta ray

No, manta rays are not harmful, as they do not have a stinger and are not poisonous. Some people confuse manta rays with their close relatives, some of which have a toxic stinger and can pierce human skin, such as the stingray. Manta rays are gentle giants of the ocean and pose no danger to humans.

What does a manta ray eat?
