The genus Manta contains two species of manta rays: the Reef Manta Ray ( Manta alfredi ) and the Giant Oceanic Manta Ray ( Manta birostris ), which are the largest species of the rays in the family Mobulidae, and the largest rays in the world.

Manta rays are circumglobal and are typically found in tropical and subtropical waters, although oceanic manta rays can be found in temperate waters.

Manta rays have a distinctive body shape with triangular ‘ wings ’ and paddle-like lobes extending in front of their mouths.

Manta rays have a much thicker mucus body coating than other rays.

Manta rays frequently visit cleaning stations where small fish such as wrasse, remora, and angelfish swim in the manta's gills and over its skin to feed, in the process cleaning it of parasites and dead tissue.

Manta rays are bottom feeders and filter feeders.

Manta rays are often host to remoras ( Remorina spp.

Manta rays are very rarely kept in captivity, primarily due to their size.

who used to be Manta S. C. and among others were Green Cross F. C., America, Juventud Italiana and River Plate However, most inhabitants are fans of Barcelona Sporting Club and Club Sport Emelec the teams with most fans base in Manabí.

Panama hats are favorite souvenirs among visitors of Manta.

Their two most notable foes are the Dirty Bubble, their arch nemesis, a sentient giant bubble, and Man Ray, a Manta ray-themed villain who is a parody of Black Manta, the arch nemesis of Aquaman.

* His friends and enemies are similar to Batman and Aquaman's friends and enemies such as: Barnacle Boy, Elastic Waistband, Miss Appear and Man Ray being parodies of Aqualad, Robin, Plastic Man, Elongated Man, Mr. Fantastic, Wonder Woman and Black Manta.

However, because of his general laziness, Yoh's abilities are relatively unrefined and he is lacking in knowledge of more sophisticated techniques at the beginning of the series when he first arrives in Tokyo and meets Manta.

* Manta Mirage, a McLaren M8B coupe replica, has split doors where the lower half open as scissor doors and the upper half are removable gullwing doors, although some owners connected the two halves making them either traditional gullwing doors or butterfly doors.

Manta ray embryos also breath by buccal pumping, as mantas give live birth and embryos are not connected to their mother by umbilical cord or placenta as in many other animals.

In 1938, the organ in the high choir was dismantled, at the same time that a series of stained-glass are replaced in the southern façade ( designed by Abel Manta and executed by Ricardo Leone ).

Jackson and Mera are able to work together to seal Black Manta, Siren and the rest of the invaders away in the Bermuda Triangle.

A flashback shows that Aquaman created a team known as the Others ( forged of six Atlantean relics from the Dead King's tomb ) who are trying to catch Black Manta, but it fails and Black Manta escapes.

In " Mayhem of the Music Meister " Black Manta along with Gorilla Grodd and Clock King are mindcontrolled by the Music Meister.

Because of these features, beaches in the Ria Formosa area are well known, like Vale do Lobo, Faro Island, Culatra, Barril, Tavira Island, Cabanas de Tavira, Cacela Velha and Manta Rota.

In later events, Black Manta was used as a test subject to make water breathers, using genetic manipulation.

Manta possesses a number of Universities and High Schools.

The Manta was known to be one of the best handling cars in its class and went on to win a large number of rallies in Europe and the United States.

The center of the culture was in the area of Manta which was named in their honor.

The coastal lowlands north of Manta were conquered, not by the Spanish, but by blacks from the Guinean coast who, as slaves, were shipwrecked en route from Panama to Peru in 1570.

Although the U. S. have been refused to renew their lease on the Manta military airbase, deliveries included trucks, patrol boats, GPS, night-vision and rifles.

Ecuador and the U. S. agreed in 1999 to a 10-year arrangement whereby U. S. military surveillance aircraft could use the airbase at Manta, Ecuador, as a Forward Operating Location to detect drug trafficking flights through the region.

* Mystery Manta: A small manta ray with dorsal markings.

In the last few decades, the scientific consensus had been that there was just one species, Manta birostris.

A third possible species in the genus, preliminarily referred to as Manta sp.

M. birostris overlaps in distribution with Manta sp.

Manta Rays have many common names including Atlantic manta, Pacific manta, devilfish, and just manta.

For a brief period each year, the rays of the sun are warm enough to melt some of the snows piled a mile deep at the base of the headwalls, and then the pinnacles glisten in the daytime at high noon, and billions of gallons of water begin their slow seepage under the glaciers and across the rockstrewn hanging valleys on their long, meandering journey to the sea -- running east past the sky-carving massifs of Gurla Mandhata and Kemchenjunga, then turning south and curling down through the jungles of Assam, past the Khasi Hills, and into Bengal, past Sirinjani and Madaripur, until the hard water of the melting snows mingles with the soft drainage of fields and at length fans out to meld with the teeming salt depths of the Bay of Bengal.

High-energy cosmic rays impacting Earth's atmosphere ( or any other matter in the Solar System ) produce minute quantities of antiparticles in the resulting particle jets, which are immediately annihilated by contact with nearby matter.

Antiparticles are produced naturally in beta decay, and in the interaction of cosmic rays in the Earth's atmosphere.

Rainbows are formed when densely compressed air is touched by the rays of the sun .< ref > Fairbanks, Arthur.

The Gaussian theory, however, is only true so long as the angles made by all rays with the optical axis ( the symmetrical axis of the system ) are infinitely small, i. e. with infinitesimal objects, images and lenses ; in practice these conditions are not realized, and the images projected by uncorrected systems are, in general, ill defined and often completely blurred, if the aperture or field of view exceeds certain limits.

All rays which issue from O and pass through the aperture stop also pass through the entrance and exit pupils, since these are images of the aperture stop.

If the object point be infinitely distant, all rays received by the first member of the system are parallel, and their intersections, after traversing the system, vary according to their perpendicular height of incidence, i. e. their distance from the axis.

These aberrations are avoided if, according to Abbe, the sine condition, sin u ' 1 / sin u1 = sin u ' 2 / sin u2, holds for all rays reproducing the point O.

( Technically, the quantum states are rays of vectors in the Hilbert space, as corresponds to the same state for any nonzero complex number c .)

The class is divided into two subclasses: Elasmobranchii ( sharks, rays and skates ) and Holocephali ( chimaeras, sometimes called ghost sharks, which are sometimes separated into their own class ).

Another exception are the electric rays, which have a thick and flabby body, with soft, loose skin devoid of dermal denticles and thorns.

In rays, the pectoral fins have connected to the head and are very flexible.

The extant members of the Chondrichthyes are the sharks and rays, belonging to the subclass Elasmobranchii, and the chimaeras, belonging to the subclass Holocephali.

For example, trace ( but detectable ) amounts of carbon-14 (< sup > 14 </ sup > C ) are continually produced in the atmosphere by cosmic rays impacting nitrogen atoms, and argon-40 (< sup > 40 </ sup > Ar ) is continually produced by the decay of primordially occurring but unstable potassium-40 (< sup > 40 </ sup > K ).

Very abundant hydrogen and helium are products of the Big Bang, but the next three elements are rare since they had little time to form in the Big Bang and are not made in stars ( they are, however, produced in small quantities by breakup of heavier elements in interstellar dust, as a result of impact by cosmic rays ).

Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit.

In a final, production quality rendering of a ray traced work, multiple rays are generally shot for each pixel, and traced not just to the first object of intersection, but rather, through a number of sequential ' bounces ', using the known laws of optics such as " angle of incidence equals angle of reflection " and more advanced laws that deal with refraction and surface roughness.

Cathode rays ( also called an electron beam or e-beam ) are streams of electrons observed in vacuum tubes.

Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube.
