Sharks are a group of fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans. Under this broader definition, the earliest known sharks date back to more than 420 million years ago.Acanthodians are often referred to as "spiny sharks"; though they are not part of Chondrichthyes proper, they are a paraphyletic assemblage leading to cartilaginous fish as a whole.
Since then, sharks have diversified into over 500 species. They range in size from the small dwarf lanternshark (Etmopterus perryi), a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark (Rhincodon typus), the largest fish in the world, which reaches approximately 12 metres (40 ft) in length. Sharks are found in all seas and are common to depths of 2,000 metres (6,600 ft). They generally do not live in freshwater although there are a few known exceptions, such as the bull shark and the river shark, which can survive and be found in both seawater and freshwater. Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics. They have several sets of replaceable teeth.
Creative Commons (CC) is a non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators. An easy-to-understand one-page explanation of rights, with associated visual symbols, explains the specifics of each Creative Commons license. Creative Commons licenses do not replace copyright, but are based upon it. They replace individual negotiations for specific rights between copyright owner (licensor) and licensee, which are necessary under an "all rights reserved" copyright management, with a "some rights reserved" management employing standardized licenses for re-use cases where no commercial compensation is sought by the copyright owner. The result is an agile, low-overhead and low-cost copyright-management regime, profiting both copyright owners and licensees. Wikipedia uses one of these licenses.
A monster truck is a vehicle that is typically styled after pickup truck bodies, modified or purposely built with extremely large wheels and suspension. They are used for competition and popular sports entertainment and in some cases they are featured alongside motocross races, mud bogging, tractor pulls and car-eating robots.
A monster truck show sometimes involves the truck crushing smaller vehicles beneath its huge tires. These trucks can run up and over most man-made barriers, so they are equipped with remote shut-off switches, called the Remote Ignition Interruptor (RII), to help prevent an accident if the driver loses control at any time. At some events, only one truck is on the course at a time, while most feature two drivers racing each other on symmetrical tracks, with the losing driver eliminated in single-elimination tournament fashion.
In recent years, many monster truck competitions have ended with a "freestyle" event. Somewhat akin to dressage with giant trucks, drivers are free to select their own course around the track and its obstacles. Drivers will often try "donuts", wheelstands and jumps during this segment. Additional items for the drivers to crush, usually including a motor home, are frequently placed on the track specifically for the freestyle event. Other obstacles sometimes placed on the track include school buses and small airplanes.
"Look Away" is a 1988 power ballad by American rock band Chicago. Written by Diane Warren, produced by Ron Nevison, and with Bill Champlin on lead vocals, it is the second single from the band's album Chicago 19. The song topped the Billboard Hot 100 for two weeks in December 1988, matching the chart success of the group's "If You Leave Me Now" (1976) and "Hard to Say I'm Sorry" (1982). "Look Away" is Chicago's seventh song to have peaked at number one on the Adult Contemporary chart as well as the number one song on the 1989 year-end Billboard Hot 100 chart.
The song, unlike hits from early in Chicago's career, does not prominently feature horns. It is also the band's first number-one single following the departure of Peter Cetera, who left the group in 1985. The song was originally offered to the Swedish hard rock band Europe by Ron Nevison who was producing their album Out of This World at the time and thought that the album needed another ballad. The singer of the band, Joey Tempest didn't like the song and turned down the offer.
Arutz HaYeladim (Hebrew: ערוץ הילדים, The Kids' Channel) is an Israeli youngster cable television channel owned by NOGA Communications Limited. It was one of the first cable channels in Israel with Arutz HaMishpaha, Arutz HaSratim and Arutz HaSport.
The channel first launched in 1989, as a part of Israeli cable's trial broadcasting prior to the 1990 official launch. At first the channel broadcast only two hours a day, and in its first two years was based primarily on purchased programs. In 1991, the channel began involving segments with human hosts and presenters. These segments grew to bigger live shows over the years and gave some of the presenters their tickets to stardom. The channel's growing popularity among children also led to many educational campaigns, regarding issues such as safety and tolerance.
In 1996, the channel's content was transferred to the control of the new company "Noga Tikshoret" ("Venus communication"), and the channel updated its programming to more interactive nature while also adding more original programs - a direction that the channel is following to this day.

SUBSCRIBE! http://www.youtube.com/user/footytubenrl?sub_confirmation=1 A faultless first half has powered the Sharks to a resounding 44-12 win over top-four rivals the Roosters at a sold out Central Coast Stadium on Saturday afternoon. Cronulla's sixth-straight win over the Tricolours came on the back of an uncharacteristically brilliant opening stanza that saw them open up a 20-12 lead thanks to a 19/19 completion rate and 66 per cent of possession. Their second half was equally as impressive with Shane Flanagan's men racing in four unanswered tries in what was a perfect response following last week's disappointing effort against the Sea Eagles. Five-eighth James Maloney bounced back from last week's underwhelming display with a man-of-the-match performance against his former side ...

**This may not be appropriate for our younger viewers.** Follow up video showing the full story here: https://youtu.be/UffOvJnD-4s This is not our usual kids content and Gabe and Garrett did not go on this trip, this video is from my trip to Guadalupe Island (I'm their dad). On a recent great white shark cage diving trip we experienced a very rare event, a shark breaching the side of the cage. What might appear to be an aggressive great white shark trying to attack the cage, this is not the case. These awesome sharks are biting at large chunks of tuna tied to a rope. When a great white shark lunges and bites something, it is temporarily blinded. They also cannot swim backwards. So this shark lunged at the bait, accidentally hit the side of the cage, was most likely confused and no...
A man was flying his drone and it videotaped two Great White sharks over six feet long near a boat towing people in inflatable water toys.

I went to the marina saw a man in a speedo scratching himself and staring at sharks his shirt was unbuttoned long grey chest hairs and the sharks just kept swimming more bored than annoyed and the man on the tape says that they'd suffocate if the sharks would stop swimming in circles even though there's no place for them to go in this aquarium they just keep swimming in circles they're such noble creatures the marina's main feature and they glide through captivity with oceans more dignity than we'll ever know judging by that speedo and the man on the tape says that they'd suffocate if the sharks would stop swimming in circles even though there's no place for them to go in this aquarium they just keep swimming in circles
