Ray may refer to:
National Geographic or NatGeo may refer to:
Manta rays are large rays belonging to the genus Manta. The larger species, M. birostris, reaches 7 m (23 ft 0 in) in width while the smaller, M. alfredi, reaches 5.5 m (18 ft 1 in). Both have triangular pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Elasmobranchii (sharks and rays) and are placed in the family Myliobatidae (eagle rays).
Mantas are found in temperate, subtropical and tropical waters. Both species are pelagic; M. birostris migrates across open oceans, singly or in groups, while M. alfredi tends to be resident and coastal. They are filter feeders and eat large quantities of zooplankton, which they swallow with their open mouths as they swim. Gestation lasts over a year, producing 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 pollution, entanglement in fishing nets, and 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 Animals, but are more vulnerable closer to shore. Areas where mantas congregate are popular with tourists. Only a few aquariums are large enough to house them. In general, these large fish are seldom seen and difficult to study.
A video blog or video log, usually shortened to vlog/ˈvlɒɡ/, is a form of blog for which the medium is video, and is a form of web television. Vlog entries often combine embedded video (or a video link) with supporting text, images, and other metadata. Entries can be recorded in one take or cut into multiple parts. The vlog category is popular on YouTube.
Video logs (vlogs) also often take advantage of web syndication to allow for the distribution of video over the Internet using either the RSS or Atom syndication formats, for automatic aggregation and playback on mobile devices and personal computers (See video podcast).
A video log created while riding a motorcycle is known as a motovlog (abbreviation of motorcycle video log).
On January 2, 2000, Adam Kontras posted a video alongside a blog entry aimed at informing his friends and family of his cross-country move to Los Angeles in pursuit of show business, marking the first post on what would later become the longest-running video blog in history. In November of that year, Adrian Miles posted a video of changing text on a still image, coining the term vog to refer to his video blog. In 2004, Steve Garfield launched his own video blog and declared that year "the year of the video blog".
Dr Andrea Marshall is a marine biologist known for her research into manta rays, and a founder of the Marine Megafauna Foundation. She was the subject of the Natural World documentary Andrea: Queen of Mantas.
She completed her PhD on manta rays in 2008 and now works at the Manta Ray & Whale Shark Research Center at Tofo Beach, Mozambique, where she also lives.
She is credited with the inclusion of manta rays in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITIES). She gave a TED talk in 2012 and was named a National Geographic "Emerging Explorer" in 2013.
She developed Manta Matcher, an online citizen science database for identifying individual manta rays from their unique markings.
In this fascinating biology segment, Jonathan explores the world of skates and rays. From the plankton-eating Manta ray to the Electric Torpedo ray, these animals have a variety of surprising adaptations for survival in the ocean. ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

Boston Red Sox 1 at Tampa Bay Rays 3, F -- Akinori Iwamura stabbed Jed Lowrie's bad-hop grounder, had a moment of indecision about whether to flip the ball to shortstop Jason Bartlett, then he headed to second base. Once his foot touched down on the bag for the force out, the Rays were headed to the World Series, led by American League Championship Series MVP Matt Garza. A raucous celebration on and off the field followed saw Rays principal owner Stuart Sternberg presented the William Harridge trophy for winning the American League pennant. Iwamura moved across the top of the Rays' dugout, slapping palms with fans, and most of the crowd of 40,473 remained in the building, still standing and cheering for their team.

How long will you scream at the walls...
For someone to listen?
Surrender the right to resolve
Cause no one will listen
Confusion sets in
With no beginning or end
Frozen in place
The scenery's unraveling
Hanging on by a thread
The child is screaming
While holding his breath
Hanging on by a thread
The child is screaming
While holding his breath
How long will you scream at the walls...
For someone to listen?
Surrender the right to resolve
Cause no one will listen
Forever you face
The fear of being erased
No need to speak
They'll pass you by and wonder why
You're hanging on by a thread
You throw away everything
From holding your breath
How long will you scream at the walls...
For someone to listen?
Surrender the right to resolve
Cause no one will listen
Biting your tongue
The top of your lungs
Biting
Biting
Biting your tongue
How long will you scream at the walls...
For someone to listen?
Surrender the right to resolve
Cause no one will listen
