These sharks get their name from the two projections that protrude from the sides of the head, much like a hammer. Anymore questions today?
Stanley Kirk Burrell (born March 30, 1962), known professionally as M.C. Hammer (and later simply Hammer), is an American rapper, dancer, entrepreneur, spokesman and occasional actor. He had his greatest commercial success and popularity from the late 1980s until the late 1990s. Remembered for his rapid rise to fame, Hammer is known for his hit records (such as "U Can't Touch This" and "2 Legit 2 Quit"), flashy dance movements, choreography and eponymous Hammer pants. Hammer's superstar-status and entertaining showmanship made him a household name and hip hop icon. He has sold more than 50 million records worldwide.
A multi-award winner, M.C. Hammer is considered a "forefather/pioneer" and innovator of pop rap (incorporating elements of freestyle music), and is the first hip hop artist to achieve diamond status for an album. Hammer was later considered a sellout due in part to overexposure as an entertainer (having live instrumentation/bands, choreographed dance routines and an impact on popular culture being regularly referenced on television and in music) and as a result of being too "commercial" when rap was "hardcore" at one point, then his image later becoming increasingly "gritty" to once again adapt to the ever-changing landscape of rap. Regardless, BET ranked Hammer as the #7 "Best Dancer Of All Time". Vibe's "The Best Rapper Ever Tournament" declared him the 17th favorite of all-time during the first round.
The hammerhead sharks are a group of sharks in the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a "cephalofoil". Most hammerhead species are placed in the genus Sphyrna while the winghead shark is placed in its own genus, Eusphyra. Many not necessarily mutually exclusive functions have been proposed for the cephalofoil, including sensory reception, maneuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves. Unlike most sharks, hammerheads usually swim in schools during the day, becoming solitary hunters at night. Some of these schools can be found near Malpelo Island in Colombia, Cocos Island off Costa Rica, and near Molokai Island in Hawaii. Large schools are also seen in southern and eastern Africa.
Shark finning refers to the removal and retention of shark fins while the remainder of the living shark is discarded in the ocean. Sharks returned to the ocean without their fins are often still alive; unable to move effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. Shark finning at sea enables fishing vessels to increase profitability and increase the number of sharks harvested, as they only have to store and transport the fins, by far the most profitable part of the shark. Some countries have banned this practice and require the whole shark to be brought back to port before removing the fins.
Shark finning increased since 1997 largely due to the increasing demand for shark fins for shark fin soup and traditional cures, particularly in China and its territories, and as a result of improved fishing technology and market economics. The International Union for Conservation of Nature’s Shark Specialist Group say that shark finning is widespread, and that "the rapidly expanding and largely unregulated shark fin trade represents one of the most serious threats to shark populations worldwide". Estimates of the global value of the shark fin trade range from US$540 million to US$1.2 billion (2007). Shark fins are among the most expensive seafood products, commonly retailing at US$400 per kg. In the U.S., where finning is prohibited, a bowl of shark-fin soup can sell for $70 to $150. Some buyers regard the whale shark and the basking shark as trophy species, and pay $10,000 to $20,000 for a fin.
Chondrichthyes (//; from Greek χονδρ- chondr- 'cartilage', ἰχθύς ichthys 'fish') or cartilaginous fishes are jawed fish with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone. 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).
