The manta ray is a large species of flattened fishclosely related to other cartilaginous fish such as sharks. The manta ray is the largest species of ray in the world with some manta ray individuals reaching up to 9 meters wide. The manta ray is most commonly found in the warmer, tropical of waters of the world's oceanstypically around coral reefs and along the continental shelves where food is in abundance.
However, due to their enormous sizemanta rays are also commonly spotted hunting out in the open ocean. The manta ray is a solitary animal and is also a graceful swimmer. Like other large species of fishmanta rays swim by moving their pectoral fins up and down which propels their enormous body through the surrounding water.
The short tail of the manta ray also allows the manta ray to be more acrobatic with its movement, and they have even be seen leaping out of the water. Manta rays are known to frequently visit cleaning stations where small fish such as wrasse and angelfish swim in the manta ray's gills and over its skin to feed, in the process cleaning it of parasites and dead tissue.
Manta Ray Anatomy
Manta rays are generally not interested in eating these smaller fish as they are providing a great service to the manta ray. Unlike many sharks, manta rays do not actually have teeth and instead sieve the food particles out of the water using rows of tiny plates in their mouths, which they funnel in their mouths as they swim. Manta rays eat tiny marine organisms including microscopic planktonsmall fish and crustaceans. Despite its large sizethe relatively docile nature of the manta ray means that it is actually preyed upon by a number of large marine predators.
Large species of shark such as the great white shark, killer whales and also humans are known to hunt the manta ray. After mating the female manta ray lays a couple of eggs which actually develop and then hatch inside her. This process is known as aplacental viviparity and is quite commonly seen in the reproduction of a number of shark and ray species.
Within 6 weeks of hatching, the female manta ray gives birth to 1 or 2 manta ray pups, which develop into large adults fairly quickly.
Today, although the manta ray is not considered to be a species that is in imminent danger of extinction in the wild, the manta ray population numbers have been declining more quickly in recent years. Manta rays are particularly susceptible to pollution in the water and are quickly affected by overfishing in certain areas, and therefore a lack of food. Share This Article.

They also have lobes that extend out from the front of the mouth. They can be as wide as 23 feet and they can weigh as much as 2, pounds. They are dark colored which allows them to blend in well to their surroundings. They can be black, gray, blue, or brown. They often feature unique patterns of blotched coloring that have been used to successfully identify individuals. The mouth of the manta ray is very large and they have 18 rows of teeth.
The teeth are only found on the lower jaw. The fins of the adults can expand very wide so they do take up a great deal of space in the water. These wings help them to move with ease without using lots of energy. They do have a tail, but there is no spine for it. The body of the manta ray consists of flexible cartilage instead of bone.
The body is very flat.Snell's Law \u0026 Index of Refraction - Wavelength, Frequency and Speed of Light
They are closely related to sting rays as well as to sharks. The flat body allows them to hide easily along the sediment at the bottom of the water which keeps them safe from predators. The flat body for them has been a successful part of their overall survival for millions of years. The cephalic lobes are an extension of the wings, and they offer support.
They have been known to use the lobes to help them for a variety of tasks and actions. They also rely on them to help reduce the amount of resistance that they experience when they are taking part in swimming for long distances. The mouth is always found in the front of the manta ray. That is a great way to tell them apart from other types of rays.All rights reserved.
Two giant oceanic manta rays feed on plankton. Manta rays are the largest species of ray and live in tropical, subtropical, and temperate ocean waters across the globe. The sea creatures live in tropical, subtropical, and temperate ocean waters across the globe. For decades, scientists thought there was just one species of manta ray.
While the smaller reef manta has an impressive wingspan of about 11 feet wide on average, the giant oceanic manta ray—the largest species of ray—can have a wingspan of up to 29 feet.
Both species of manta ray are filter feeders: they swim with their mouths wide open, drawing in zooplankton and krill, which they sift through rows of tiny rakes that line their mouths called gill plates. They use creative techniques when feedingoften doing repeated somersaults to stay in a single spot that is packed with krill, or chain-feeding—following each other in a circle, mouths open, to create a cyclone effect, trapping food in a spiral.
Giant manta rays live alone or in small groups, typically congregating to feed. Manta rays make regular visits to cleaning stations—spots on a coral reef where sea animals go to be cleaned by smaller creatures—where they stay still for several minutes while cleaner fish remove parasites and dead skin. Many individual manta rays return to the same stations over and over. Manta rays have the largest brain-to-size ratio of any cold-blooded fish.
Studies have shown that manta rays may recognize themselves in the mirror, an ability indicative of high cognitive function, also shown by dolphins, primates, and elephants.
Studies have also shown that manta rays are able to create mental maps of their environmentthrough smell and visual cues, indicating highly developed long-term memory. Female manta rays hit sexual maturity at around eight to 10 years old and tend to give birth once every couple of years, usually to one pup, or occasionally two. Pregnancy lasts about 12 to 13 months and manta rays give birth to live pups.
Babies look like smaller version of adult manta rays when born and can immediately survive without parental care. Both sub-species of manta ray are classified as vulnerable by the IUCN. Their greatest threat is overfishing. Manta rays are fished for their meat, and, increasingly, their gill plates. Sincemanta rays have been protected in international waters by the Convention on Migratory Species, an international treaty that protects migrating wild animals. In addition, several countries including Ecuador, Peru, Mexico, the Philippines, and New Zealand have fishing bans in place.
Marine biologist and National Geographic grantee Joshua Stewart is fighting to protect giant oceanic manta rays by studying their movements. Read Caption. Manta Rays.

Giant manta rays are slow-growing, migratory animals with small, highly fragmented populations that are sparsely distributed across the world. The main threat to the giant manta ray is commercial fishing, with the species both targeted and caught as bycatch in a number of global fisheries throughout its range. Manta rays are particularly valued for their gill rakers, which are traded internationally.
Information on the global distribution of giant manta rays and their population sizes is lacking. Ecuador is thought to be home to the largest population of giant manta ray, with large aggregation sites within the waters of the Machalilla National Park and the Galapagos Marine Reserve. Overall, given their life history traits, particularly their low reproductive output, giant manta ray populations are inherently vulnerable to depletions, with low likelihood of recovery.
Additional research is needed to better understand the population structure and global distribution of the giant manta ray. Manta rays are recognized by their large diamond-shaped body with elongated wing-like pectoral fins, ventrally placed gill slits, laterally placed eyes, and wide terminal mouths.
Manta rays come in two distinct color types: chevron mostly black back and white belly and black almost completely black on both sides. There are two species of manta rays: giant manta rays Manta birostris and reef manta rays Manta alfredi.
Giant manta rays are generally larger than reef manta rays, have a caudal thorn, and rough skin appearance. The giant manta ray is a migratory species, and seasonal visitor along productive coastlines with regular upwelling, in oceanic island groups, and near offshore pinnacles and seamounts.
The timing of these visits varies by region and seems to correspond with the movement of zooplankton, current circulation and tidal patterns, seasonal upwelling, seawater temperature, and possibly mating behavior. Although the giant manta ray tends to be solitary, they aggregate at cleaning sites and to feed and mate. Manta rays primarily feed on planktonic organisms such as euphausiids, copepods, mysids, decapod larvae and shrimp, but some studies have noted their consumption of small and moderately sized fishes as well.
Manta rays use many different types of feeding strategies, such as barrel rolling doing somersaults over and over again and creating feeding chains with other mantas to maximize prey intake. Giant manta rays also appear to exhibit a high degree of plasticity in terms of their use of depths within their habitat.
During feeding, giant manta rays may be found aggregating in shallow waters at depths less than 10 meters.Manta rays are large rays belonging to the genus Mobula formerly its own genus Manta. The larger species, M.
Both have triangular pectoral finshorn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Myliobatiformes stingrays and relatives and are placed in the family Myliobatidae eagle rays.
Mantas are found in warm temperatesubtropical and tropical waters. Both species are pelagic ; M. They are filter feeders and eat large quantities of zooplanktonwhich they gather with their open mouths as they swim. Gestation lasts over a year and mantas give birth to live pups. Mantas may visit cleaning stations for the removal of parasites. Like whales, they breach for unknown reasons. Both species are listed as vulnerable by the International Union for Conservation of Nature.
Anthropogenic threats include pollutionentanglement in fishing netsand direct harvesting for their gill rakers for use in Chinese medicine. Their slow reproductive rate exacerbates these threats. They are protected in international waters by the Convention on Migratory Species of Wild Animalsbut are more vulnerable closer to shore.
Areas where mantas congregate are popular with tourists. Only a few public aquariums are large enough to house them. The name "manta" is Portuguese and Spanish for mantle cloak or blanketa type of blanket-shaped trap traditionally used to catch rays.
Manta rays are members of the order Myliobatiformes which consists of stingrays and their relatives. Mantas evolved from bottom-dwelling stingrays, eventually developing more wing-like pectoral fins. The scientific naming of mantas has had a convoluted history, during which several names were used for both the genus CeratopteraBrachioptilon Daemomantaand Diabolicthys and species such as vampyrusamericanajohniiand hamiltoni.
All were eventually treated as synonyms of the single species Manta birostris. Authorities were still not in agreement and some argued that the black color morph was a different species from the mostly white morph.
This proposal was discounted by a study of the mitochondrial DNA of both. Two distinct species emerged: the smaller M. A third possible species, preliminarily called Manta sp. While some small teeth have been found, few fossilized skeletons of manta rays have been discovered.
Their cartilaginous skeletons do not preserve well, as they lack the calcification of the bony fish. Only three sedimentary beds bearing manta ray fossils are known, one from the Oligocene in South Carolina and two from the Miocene and Pliocene in North Carolina.
These were originally described as Manta fragilisbut were later reclassified as Paramobula fragilis.On 29 April before the Sightings TV show camera crew, this ship put on a spectacular performance before professional cameras.

This is precisely what I have been closing my lectures with for the past four years. Well Hal, you asked for it! Before Rich died of cancer, Andrews took my questions to him.
Rich confirmed: 1. There are two types of UFOs. The ones we build, and the ones THEY build. We learned from both crash retrievals and actual "Hand-me-downs. After the Nixon "Purge", administration was handled by an international board of directors in the private sector. Rich observed that the impression Kelly Johnson's contacts had was a negative impression and Kelly implied in rare conversations on the subject that "Factions" from "Out there" were a threat, more than they were a blessing, and that the cost of having "Them" around was "Unimaginable" and "Unbelievable.
It was Ben Rich's opinion, that the public should not be told. He believed they could not handle the truth, ever. Only in the last months of his decline did he begin to feel that the "International corporate board of directors" dealing with the "Subject," could represent a bigger problem to citizens' personal freedoms under the United States Constitution than the presence of offworld visitors themselves.
