Manta ray

Manta rays are very large fish.

They live in warm ocean waters. They have fins that look like wings. These fins help them swim through the sea.

Mantas eat tiny bits of food. They swim with their mouths open to catch them.

This helps them get enough food to grow.

These fish are very smart. They have big brains for their size. Some even know themselves in a mirror.

They can swim alone or in groups. Some mantas leap out of the water. They might do somersaults in the air.

Small fish help keep them clean. These tiny fish pick off pests. It is a helpful way to live.

Manta rays are large fish that live in warm waters.

There are three known species. The largest is the giant manta ray. The smallest is the reef manta ray.

Mantas have wing-like fins. They use these fins to swim through the ocean. They are filter feeders. This means they eat tiny bits of food called zooplankton. To eat, they swim with their mouths open. They use special parts called gill rakers to catch food.

Some mantas swim in big circles to eat together. They can form a group called a cyclone. This group can have 150 mantas in it.

Mantas are very smart. They have large brains for their size. Some can even pass a mirror test. This shows they may know themselves.

These animals face many dangers. They can get stuck in fishing nets. Pollution also hurts them. Some people hunt them for their gill plates. Because they grow slowly, these threats are serious.

Small fish help them by cleaning pests off their skin.

Manta rays are huge, amazing fish that live in warm ocean waters.

They belong to a group of relatives called the Myliobatiformes. This group includes many different types of stingrays. Mantas are special because they have very large brains. In fact, they have one of the highest brain-to-body ratios of all fish. Scientists even found that they can pass a mirror test. This suggests they may have a sense of self-awareness.

These rays move through the water using wing-like pectoral fins. They are filter feeders, which is a way of eating tiny food. To eat, they swim with their mouths wide open. They use pinkish-brown gill rakers to catch small bits of food. These rakers are like tiny sieves that trap zooplankton. Most of their food comes from deeper parts of the ocean. Sometimes, they swim in a huge circle called a cyclone. This group can have up to 150 mantas swimming together.

Scientists have spent a long time studying these creatures. The name "manta" comes from Portuguese and Spanish words for a cloak or blanket. This is because their shape looks like a large piece of fabric. In 1829, Dr. Edward Nathaniel Bancroft published work about these fish. They were once given many different names by researchers. Over time, experts sorted these names out. They discovered that many old names were just different ways to describe the same animal.

There are three main species of manta rays known today. The largest is Manta birostris, which can reach huge widths in the ocean.

The smallest is the reef manta ray, known as Manta alfredi. This species lives in the Indo-Pacific and the tropical East Atlantic. A third species, the Atlantic manta ray, was formally described in 2025. It is called Mobula yarae. These rays can be different colors, too. One rare pink manta ray was even spotted in Australia.

Living in the ocean can be a hard job for mantas. They face many threats from humans, such as pollution and fishing nets. Some people also hunt them for their gill plates. Because mantas grow and have babies very slowly, these problems are serious.

To stay healthy, they often visit cleaning stations on coral reefs. At these spots, small fish pick parasites off the manta's skin. This helps the manta stay clean and healthy. They may even return to the same cleaning spot again and again.

Manta rays are large, highly intelligent fish belonging to the genus Mobula. They are members of the order Myliobatiformes, a group that includes stingrays and their relatives. These animals are part of the Myliobatidae family, which are known as eagle rays. Mantas are unique among rays because they have evolved into filter feeders. They possess a very high brain-to-body mass ratio, the largest of any fish.

This intelligence is evidenced by their ability to pass the mirror test, suggesting a level of self-awareness. They inhabit warm temperate, subtropical, and tropical waters across the globe.

To feed, mantas use a specialized mechanism called filter feeding. They swim through the water with large, rectangular mouths facing forward. As they move, they use horn-shaped cephalic fins to channel water and food into their mouths. Inside their gill arches, they have pinkish-brown gill rakers. These rakers are made of spongy tissue that acts like a sieve to collect zooplankton.

While they eat shrimp and krill at the surface, research shows most of their diet comes from mesopelagic sources in deeper water. To breathe, they must keep swimming with their mouths open to pass oxygenated water over their gills.

There are three recognized species of manta rays. The largest is Manta birostris, which can reach widths of at least 7 meters. This species is highly migratory and travels across open oceans. The smallest is Manta alfredi, the reef manta ray, which reaches about 3.7 meters in width. M. alfredi tends to be a resident, coastal species found in the Indo-Pacific and tropical East Atlantic.

A third species, Mobula yarae, was formally described in 2025. It is known as the Atlantic manta ray and inhabits the tropical West Atlantic, including the Caribbean.

The history of manta naming has been quite complex. In 1829, Dr. Edward Nathaniel Bancroft published work on the "sea-devil" in Jamaica. Over many years, researchers used various names like Ceratoptera and Diabolicthys. Most of these were eventually determined to be synonyms for Manta birostris. The name "manta" itself comes from Portuguese and Spanish words for a mantle or cloak. This refers to the shape of a traditional blanket-shaped fishing trap.

Some people call them "devilfish" because their cephalic fins look like horns.

Mantas exhibit fascinating social and survival behaviors. They often visit cleaning stations on coral reefs. At these locations, smaller fish remove parasites from the manta's skin.

Mantas may even show philopatry, which means they return to the same cleaning station repeatedly. They also engage in group feeding behaviors. They can form a "cyclone," a massive spiral of up to 150 mantas. These feeding circles can reach 10 meters in diameter and last for an hour. Some mantas even leap out of the water, a behavior called breaching, though the reason remains unknown.

Despite their size, mantas face significant biological and environmental challenges. They have a very slow reproductive rate, as gestation lasts over a year before they give birth to live pups. This makes them highly vulnerable to human threats. They face pollution, entanglement in fishing nets, and direct harvesting. Specifically, their gill rakers are highly valued and traded internationally for use in Chinese medicine.

Because of these pressures, M. birostris and M. alfredi are both listed as vulnerable by the International Union for Conservation of Nature.

Manta rays are deeply connected to the health of marine ecosystems. They serve as important components of the pelagic food web. Their presence is often a draw for tourism, as many people enjoy watching them in the wild. However, they are more vulnerable to threats when they are close to the shore. While they are protected in international waters by the Convention on Migratory Species of Wild Animals, local protection remains a critical concern for their survival.
