requiem shark that was first named in 1905 after specimens were found in the seas around theGalapagos Islands .Taxonomy
The Galapagos shark was originally described as "Carcharinus galapagensis" in 1905. Its name was later changed to "Carcharias galapagensis". This name was changed yet again later that same year, and it received its currently valid scientific name "Carcharhinus galapagensis".
Anatomy and appearance
The Galapagos shark is dark grey on top with an off-white belly and a black tail edge; its snout is long and rounded. The Galapagos' dorsal fin originates over its Pectoral axis, and it is rounded like the shark's snout; however, the tip of the dorsal fin is angled. Their average length is around 10 ft (3 m). The Galapagos shark can be found in warm tropical waters at depths ranging from 16 to 200 ft (5 to 60 m).
Diet
They are
benthic feeders, meaning they hunt prey from the sea floor, such as fish andoctopus es. Adult Galapagos sharks are alsocannibalistic , feeding on their own young if encountered.Distribution and habitat
Its distribution is widespread but patchy with populations occurring at many widely separated island sites and also in some coastal areas in the
Pacific ,Atlantic and Indian oceans. It seems that there is little or no migration between these populations.Reproduction
Reproduction is
viviparous . Litters can range from 6 to 16 pups. [ [http://www.elasmodiver.com/Galapagos%20shark.htm Galapagos shark ] ]Relationship to humans
