Mobula rays are among the most poorly known of fish. They look like sharks and manta rays, but they belong to a different group within the shark family called the Mobulidae. This family also includes two species of manta rays. Although there are many more species of mobulas than manta rays, they are very similar to each other, and it is possible that they evolved from one common ancestor. Like mantas, mobulas have long pectoral fins, which help them steer while swimming. Their bodies are covered in scales, and they feed on small animals such as crustaceans and worms.
The fact that mobulas rays are so poorly studied makes them hard to study. For example, there are no records of how many individuals exist in the wild, where they live, what threats they face, or even whether they breed in captivity. In addition, the best way to identify individual rays is by examining their teeth, which are unique to each animal. However, although mobulas are easy to spot from afar because of their distinctive shape, they are much harder to observe up close. They spend most of their lives underwater, and they swim slowly, making them difficult to see. Also, they are often too far away for divers to approach safely.
The International Union for Conservation of Nature (IUCN), World Wildlife Fund (WWF) and the Food and Agriculture Organization (FAO) recently announced that the mobula rays of the western Pacific Ocean could face extinction within 20 years.
The IUCN Red List classifies the animals as vulnerable, indicating that it is likely to become extinct within the next 40 years unless conservation measures are taken.
Mobula rays are found in tropical seas worldwide, including parts of Australia, Asia, Africa and South America. They are typically caught in nets set near shorelines where they feed on small crustaceans and plankton.
In recent years, however, commercial fisheries have targeted the rays in many areas, particularly in the Gulf of California off Mexico, where they are known locally as “cabezas de sardina.”
Because of their slow reproductive cycle, large size and tendency to jump out of water, mobulas are especially susceptible to being killed during netting operations.
A study published earlier this month in PLoS ONE showed that the number of rays caught annually in the Gulf of California declined from an average of about 300 per year in the 1970s to fewer than 25 in the late 1990s.
Researchers believe that the decline is due to increased fishing activity in the region.
There is a lot of weight to mobula rays.
The Mobula Ray is one of the largest fish species known to exist today. They are found off the coast of Africa and can grow up to 4 meters long and weigh over 1,600 kg. These rays are actually filter feeders, meaning they eat plankton. They use their mouths to sieve water, allowing them to consume small organisms like zooplankton. This makes them very important to ocean ecosystems because they help keep the oceans clean.
These rays are often caught accidentally while fishing for tuna. However, it is illegal to catch them without a permit. In addition, many people believe that Mobula Rays are endangered The due to Mobula high Ray demand is for one their of meat. The largest fish species known to exist today.

For Mobula rays, three is not a crowd.
The Pacific Ocean is home to some of the most bizarre creatures you never knew existed. One such creature is the Mobula Ray—a ray that lives in huge groups of up to 100 individuals. They live in tropical waters around Australia, Indonesia, Papua New Guinea, and the Philippines.
While it might seem strange to find a group of fish swimming together, scientists are discovering that these giant gatherings are actually quite beneficial. As part of a study published in Marine Biology, researchers found that Mobulas form large groups because they help each other avoid predators. In fact, the team observed that the rays will even move away from potential threats if there are too many of them.
This helps explain why the rays often travel in groups of over 100. And while a single ray can weigh just 10 pounds, a school of thousands could easily weigh several tons.
They use two methods of transportation: flight and fins.
The flying fish is one of nature’s wonders – and it’s hard to imagine anything better suited to a tropical beach holiday than a ray covered in tiny scales. Yet despite their beauty, many people still don’t know much about these graceful creatures. So we’ve put together a list of facts about flying fish you might not know…
1. They’re called “flying fish” because they fly like birds. But they aren’t related to birds at all; they belong to the same group of fishes known as batrachoidids.
2. Flying fish are found in warm waters around the world, including Australia, South Africa, Indonesia, Japan, Madagascar, India, Sri Lanka, Thailand, Malaysia, Singapore, China, Taiwan, Papua New Guinea, Hawaii, Mexico, Central America, Venezuela, Brazil, Colombia, Panama, Ecuador, Peru, Chile, Argentina, Uruguay, Paraguay, Bolivia, Trinidad & Tobago, Jamaica, Cuba, Puerto Rico, the Bahamas, Bermuda, the Caribbean Sea, the Gulf of Mexico, the Atlantic Ocean, the Mediterranean Sea, North Africa, the Red Sea, the Persian Gulf, the Arabian Sea, and the Pacific Ocean.
3. A single species of flying fish lives in both saltwater and freshwater environments.
4. These fish spend their entire life cycle in the ocean, except for a brief period during mating season. After hatching, the young fish grow rapidly and mature within just three months. At this stage, they begin to develop the ability to glide while underwater.
5. When they reach sexual maturity, male flying fish migrate to shallow coastal areas where females congregate. Here, the males perform elaborate courtship dances to attract the attention of the female. Once she accepts his advances, he performs another dance, and then they mate.
6. In some cases, the female lays her eggs near the surface of the sea, and the male fertilises them there. Then, once the eggs hatch, the mother carries them to deeper waters.
Smarter – and friendlier – than your average fish.
The Mobula Ray is one of the most bizarre looking creatures you could ever encounter underwater. While it looks like a cross between a shark and a ray, Mobulas are actually bony fish that live in tropical oceans around the world. They grow up to five feet long and weigh anywhere from 50 pounds to over 200 pounds.
While some species of Mobulas are known to feed on plankton and small crustaceans, others prefer to eat larger prey such as crabs, shrimp, sea cucumbers and even octopus. And while they are generally very docile towards people, they do occasionally bite when threatened.
