![]() birostris still has a vestigial remnant of a sting barb in the form of a caudal spine. Mantas evolved from bottom-dwelling stingrays, eventually developing more wing-like pectoral fins. In 2018, an analysis of DNA, and to a lesser degree, morphology, found that Mobula was paraphyletic with respect to the manta rays that is, some members of genus Mobula are closer related to the members of the genus Manta than they are to fellow Mobula, and the researchers recommended treating Manta as a junior synonym of Mobula. The genus Manta is part of the eagle ray family Myliobatidae, where it is grouped in the subfamily Mobulinae along with the smaller Mobula devil rays. Manta rays are members of the order Myliobatiformes which consists of stingrays and their relatives. Mantas are known as "devilfish" because of their horn-shaped cephalic fins, which are imagined to give them an "evil" appearance. The name "manta" is Portuguese and Spanish for mantle (cloak or blanket), a type of blanket-shaped trap traditionally used to catch rays. Only a few public aquariums are large enough to house them. Areas where mantas congregate are popular with tourists. They are protected in international waters by the Convention on Migratory Species of Wild Animals, but are more vulnerable closer to shore. Their slow reproductive rate exacerbates these threats. Anthropogenic threats include pollution, entanglement in fishing nets, and direct harvesting of their gill rakers for use in Chinese medicine. Like whales, they breach for unknown reasons.īoth species are listed as vulnerable by the International Union for Conservation of Nature. ![]() Mantas may visit cleaning stations for the removal of parasites. Gestation lasts over a year and mantas give birth to live pups. However, research suggests that the majority of their diet (73%) actually comes from mesopelagic sources. They are filter feeders and eat large quantities of zooplankton, which they gather with their open mouths as they swim. alfredi tends to be resident and coastal. birostris migrates across open oceans, singly or in groups, while M. Mantas are found in warm temperate, subtropical and tropical waters. They have the largest brains and brain to body ratio of all fish, and can pass the mirror test. They are classified among the Myliobatiformes ( stingrays and relatives) and are placed in the family Myliobatidae (eagle rays). Both have triangular pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. birostris, reaches 7 m (23 ft) in width, while the smaller, M. It is a real pleasure to dive, swim or snorkel with these giant rays! Where to dive or Swim with Manta Rays?įind below the best places where to dive or to snorkel with these giant creatures.Manta rays are large rays belonging to the genus Mobula (formerly its own genus Manta). ![]() Despite being protected by law, manta rays are still hunted in countries like the Philippines, Indonesia, Borneo, Papua and in any other countries where mantas are found. The International Union for Conservation of Nature (IUCN) declared giant manta rays as ’vulnerable’in 2011. They can also be found in the temperate waters of Southern California and Rhode Island of Unites States and in Japan. Manta Rays are generally found in warm waters across the planet. Mantas also often come to cleaning stations of the reef, wherein divers can observe them at close range. It also often swims near the water surface and will sometimes make dramatic and striking leaps into the air! When it feeds, it glides through the water with ease using its protruding flaps on each side of the head to direct food into the mouth. Ecologyīeing a plankton feeder fish, the Manta Ray is an occasional visitor to plankton-rich areas of the reef. Their color is generally white and grey but black Mantas can also be found. ![]() They can sometimes even jump out of the water to get rid off their parasites! They are usually very curious and swim around the divers. They are even harmless and can’t hurt any diver or swimmer. Their size can reach up to 9 meters and can weight up to 2 tons. Its dorsal surface is darkish with pale markings. However, Manta Rays do not have spine on its tail bases. These animals also possess venomous spines that can inflict wounds, thus, making them dangerous. Description and factsĪll rays have flattened and often kite-shaped bodies. It might be the biggest ray in the planet, but it is considered harmless. These rays are also sometimes called “Devil Rays” because of its two horn-like flaps in its mouth. One of the best experience a diver could probably have is to dive with the Manta Rays.
