The giant oceanic manta ray is the largest type of ray in the world. It is also considered one of the largest fishes in the world, along with whale sharks and basking sharks. They are often found in subtropical and tropical waters and are always seen in offshore waters. What makes them unique creatures of the ocean is how they constantly flap their cephalic lobes, which helps them filter out food from the water.

Manta rays are considered solitary creatures and will always undergo long migrations searching for food and favorable environments such as temperate waters and an extensive food source. One of the reasons manta rays aren’t as explored as other sea creatures is their wide distribution from various waters in the world and how solitary they are. In their lifespan, female manta rays give birth once every two years and

8 Fascinating and Interesting Facts About the Giant Oceanic Manta Rays

Here are some interesting facts about Manta rays that may surprise you.

They have a large set of teeth, but they don’t bite

Manta rays have a large number of teeth at their lower jay. However, as mentioned, their primary source of food is planktons. They don’t use their set of teeth to munch or grind their food. Some researchers and experts believe that manta ray’s ancestors used to chomp down or chew their food. However, it started to change when they switched up their diet and started to eat planktons instead.

They are as wide as they can be

Once they reach adulthood, an adult manta ray can stretch for up to 29 feet from the left to the right. They are also called filter-feeders as they primarily feed on zooplankton and other small types of fish.

Giant oceanic manta rays do not care about their hygiene. Instead, they occasionally visit coral reefs to help them get rid of some parasites latching onto them. One particular type of fish that cares for its hygiene is the suckerfish, which primarily feeds on parasites attached to the ray.

They go where the  food goes 

Giant oceanic manta rays are one of the best at traveling ocean waters across the globe. They constantly travel, looking for nutrient-rich waters in which zooplanktons are abundant. From shallow waters to reef shores, you can easily find them as long as there is an abundance of planktons.

They like open waters 

Unlike their stingray counterparts, who love digging sands at the bottom of the ocean, manta rays prefer the open water and are often seen flapping their pectoral fins like a bird in the sky. They love the temperature and warm waters. That’s why you can often see them gliding through subtropical and tropical waters around the world.

Awesome fun facts about oceanic giant manta rays

They are harmless

Although they are considered one of the world's largest creatures and contain rows of teeth up to 300 in number, they are not dangerous. Instead, they are quite the opposite of their large counterparts, such as the great whites. Giant oceanic manta rays are harmless and are relatively gentle and peaceful creatures of the ocean.

Unsocial creatures

They are quite solitary creatures. Giant oceanic manta rays are only social during mating season. After that season, they wander throughout the world’s waters in search of food. Furthermore, if the water area has plenty of food sources, they usually congregate and could reach up to 50 manta rays.

Largest brain

Of the number of cold-blooded creatures on the planet, the Manta Rays have the largest brain-to-body size ratio. In addition, various studies have shown that manta rays can recognize themselves looking at the mirror, a testament to the high cognitive function expressed by some of the world’s most intelligent creatures such as primates, elephants, and dolphins.


The Giant Oceanic Manta Rays are quite the species indeed. They are known as graceful creatures wandering through the open waters around the world, like how an eagle would fly in the open air. Although they are relatively massive in their ways, they are not dangerous to humans and are quite the opposite.

These sea creatures are not safe against threats made by humans, but there have been plenty of organizations protecting and conserving sea life over the years. If you want to take a closer look at them, they have a large concentration along the coast of Mexico and the West coast of Australia.
