Hound Shark
The Triakidae or houndsharks are a family (biology), family of Carcharhiniformes, ground sharks, consisting of about 40 species in nine genera. In some classifications, the family is split into two subfamilies, with the genera ''Mustelus'', ''Scylliogaleus'' and ''Triakis'' in the subfamily Triakinae, and the remainders in the subfamily Galeorhininae. Houndsharks are distinguished by possessing two large, spineless dorsal fins, an anal fin and oval eyes with nictitating eyelids. They are small to medium in size, ranging from in adult length. They are found throughout the world in warm and temperate waters, where they feed on small fish and invertebrates on the seabed and in midwater. Fossil records of this group date back to the Cenomanian. Genera Houndsharks are classified into subfamilies and genera as follows: * Galeorhininae Theodore Gill, Gill, 1862 ** ''Whiskery shark, Furgaleus'' Gilbert Percy Whitley, Whitley, 1951 (whiskery shark) ** ''Galeorhinus'' Henri Marie Ducrota ...

Leopard Shark
The leopard shark (''Triakis semifasciata'') is a species of houndshark, in the family (biology), family Houndshark, Triakidae. It is found along the Pacific coast of North America, from the U.S. state of Oregon to Mazatlán in Mexico. Typically measuring long, this slender-bodied shark is immediately identifiable by the striking pattern of black saddle-like markings and large spots over its back, from which it derives its common name. Large schools of leopard sharks are a common sight in bays and estuary, estuaries, swimming over sandy or muddy flats or rock-strewn areas near kelp beds and reefs. They are most common near the coast, in water less than deep. Active-swimming predators, groups of leopard sharks often follow the tide onto intertidal zone, intertidal mudflats to forage for food, mainly clams, Echiura, spoon worms, crabs, shrimp, bony fish, and roe, fish eggs. Most leopard sharks tend to remain within a particular area rather than undertaking long movements elsewher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stewart Springer
Stewart Springer (5 June 190623 August 1991) was an American ichthyologist and herpetologist. He was an expert on shark behavior, classification (taxonomy), and population distribution. More than 35 species of sharks, skates, rays, and other creatures are either classified by or named after him. Education Springer was a field naturalist, mostly self-taught. In 1964, 35 years after he dropped out of Butler University, Springer obtained a baccalaureate from George Washington University after having already achieved success in his chosen field of ichthyology. His interest in animal behavior was apparent early in his life, when at age 22, he identified and described a new species of lizard, '' Cnemidophorus velox'', the plateau striped whiptail. His interest in the whiptail was piqued, he said, by the fact that he was chaperoning a field trip with the Cottonwood Gulch Foundation in Arizona in 1928. His young team of Boy Scouts could catch jack rabbits and other lizards in the are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
