MessageToEagle.com - They are beautiful, remarkably elegant and extremely large oceanic creatures - named
One cannot say that they swim like fish; they rather gracefully glide through the watery realm.
They are harmless to humans and lacks the stinger of the better-known stingray.
They are also very tolerant with divers. Manta rays usually swim in pairs, and although they seem frightening,
manta rays are so gentle that many will even let humans pet them. Some experienced divers have actually taken rides
on the backs of these harmless fish.
Another their name is Devilfish, which certainly seems like a reasonable description for an enormous fish
with huge wings and a massively gaping mouth between two cephalic lobes.
For centuries it was thought that the manta ray, or "devilfish," was an evil ocean beast capable of
destroying fishing boats and devouring people.
In fact, the manta ray is one of the gentlest creatures in the sea whose only wish, it seems, is to float
peacefully in the water sucking in mouthfuls of water in search of its favorite food -- plankton.
A ground-breaking study on a mysterious ocean giant: the manta ray, is completed!
Listed as "Vulnerable", the manta ray has become increasingly threatened by fishing and accidental capture
and now needs more protection!
Scientists from the Wildlife Conservation Society, the University of Exeter (UK), and the Government of Mexico
used the latest satellite telemtry to track the open-ocean journeys of the world's largest ray.
It's very important study because "almost nothing is known about the movements and ecological needs of the manta ray,
one of the ocean's largest and least-known species," Dr. Rachel Graham, director of WCS's Gulf and Caribbean Sharks
and Rays Program, said.
Researchers from the Wildlife Conservation Society, the University of Exeter, and the Government of
Mexico have published the first-ever satellite telemetry study on the manta ray, the world?s largest ray species.
The findings will help inform ecosystem-based management plans for the rays, which are in decline worldwide due to fishing and accidental capture.

Mantas, the biggest of all rays, usually reach about 6.7 meters (22 feet) but it can even grow up to 25 feet (7.6 meters)
in width, measuring from tip of gigantic pectoral fin to tip of gigantic pectoral fin, with a weight of 2,300 kilograms (5,100 lb).
The manta ray possesses the highest brain to body ratio of all sharks and rays and gives birth to live young, usually
one or two "pups" every one or two years.
"Our real-time data illuminate the previously unseen world of this mythic fish and will help to shape management and
conservation strategies for this species," Dr. Graham added.

The research team attached satellite transmitters to manta rays off the coast of Mexico's Yucatan Peninsula over a 13-day
period. The tracking devices were attached to the backs of six individuals -- four females, one male, and one juvenile.
"The satellite tag data revealed that some of the rays traveled more than 1,100 kilometers during the study period,"
said Dr. Matthew Witt of the University of Exeter's Environment and Sustainability Institute.
"The rays spent most of their time traversing coastal areas plentiful in zooplankton and fish eggs from spawning events."
Like baleen whales and whale sharks, manta rays are filter feeders that swim through clouds of plankton with mouths agape.
The research team also found that the manta rays spent nearly all their time within Mexico's territorial waters (within 200
miles of the coastline), but only 11.5 percent of the locations gathered from the tagged rays occurred within
marine protected areas. And the majority of ray locations were recorded in major shipping routes in the region; manta
rays could be vulnerable to ship strikes.
"Studies such as this one are critical in developing effective management of manta rays, which appear to be declining
worldwide," said Dr. Howard Rosenbaum, Director of WCS's Ocean Giant Program.
Manta rays are apparently declining in the Caribbean and in other tropical regions of the world's oceans, in part because they
are captured for shark bait and a demand for gill rakers (small, finger-like structures that filter out the ray's minute
zooplankton prey) in the traditional Chinese medicinal trade.
The paper on study led by Dr. Rachel Graham was published May 11 in the online journal PLoS ONE.
Unexplained Sounds Coming From The Ocean
Several very unusual sounds coming from the oceans have been recorded by scientists world-wide.
Are the sounds caused by very large life forms lurking in the unexplored darkness of Earth's deep oceans or perhaps something else?
Something is down there and experts do not know what it is...
Fascinating Gigantic Creatures Today Totally Extinct 13,000 Years Ago Coexisted With Early Americans
The Ice Age world was, geologically, just a moment ago. Fascinating but today extinct giant animals, like mammoths,
mastodons and giant ground sloths, coexisted with early Americans in those days....
For millions of years, these animals survived, living in temperate climates and on the wind-swept lands of the frozen north – great
beasts weighing as much as eight tons and bearing tusks up to 16 feet long.
Lichen Crab Spider With A Human "Face"
A Lichen Crab spider is harmless to humans but its look can be a little frightening.
The spider has a human face on its back!
It is a very rare spider. Since 1890 only 41 one of them have ever been seen in Britain.
Completely Unknown Giant Organism Discovered In Cincinnati
It's a completely new discovery! Never before has such an unusual and mysterious creature been discovered anywhere.
Experts say it seems to defy all known groups of organisms and descriptions, pictures of it, leave people with more questions than answers.
There is no doubt we are dealing with a biological creature, scientists say. When it lived it was gigantic and it stood upright.
Scots Are Descendants Of A Lost Race
DNA can be used as a telescope to look back into the past, and this is excatly what a group of scientists have done to cast more light on an ancient mystery.
New ground-breaking study suggests that Scots are descendants of long lost tribes from the Sahara.
In addition, the study also reveals that Scots are very closely related to Napoleon Bonaparte!
Amazing Phenomenon Of Singing Plants
Plants are very much alive. Not only do they dislike human noise
but they also posses the capacity to learn and communicate.
Perhaps even more astonishing is that plants can also make music.
Have you ever heard the incredible music of the plants? Plants can actually sing and compose music and listening to
it, is truly beautiful and relaxing!
Who Installed "This Object" At The Bottom Of The Ocean?
Our oceans are full of secrets, and this is one of them.
Deep beneath the waters we find ruins of ancient lost civilizations, wreckage of old ships and planes, and sometimes we come across very strange, unidentified objects.
Looking at this odd construction, one has to ask - Who installed this object at the bottom of the ocean?
6 Surprising Things Falling From The Sky
Stories of strange things falling from the sky date back a long time ago.
Over the years, there have been many bizarre instances recorded when things have fallen from the skies that simply do not belong there.
We have put together a list of some surprising things that fell from the heavens.
These are things you certainly don't expect to fall down on you...
Dangerous Fast and Furious - Birth Of Africa's New Ocean - with video
The only places where mid-ocean ridges appear above sea level are Ethiopia and Iceland.
Two new studies into the so-called “plumbing systems” that lie under volcanoes could bring scientists closer to predicting large
eruptions and reveal new information about where magma is stored and how it moves through the geological plumbing network.
Secret Properties Of Water - Still A Mystery!
The true nature of water is unknown. It has a variety of absolutely fascinating properties, we still known very little about.
One of its most unique properties is that water has a memory and its behavior can be compared to our modern CD storing digital data or magnetic tape!
This ability, among many others, is particularly astonishing and still cannot be explained in terms of conventional science.
