Taxonomy[ change change source ] The Galapagos shark was originally described as Carcharias galapagensis by Robert Evans Snodgrass and Edmund Heller inand was later moved to the genus Carcharhinus.
The requiem sharks are members of the Carcharhinidae family that includes some of the best-known and most common types of sharks.
Galapagos and white tipped reef sharks have rounded snouts and are more common throughout Galapagos than the other species. The Galapagos shark is dark grey on top with an off-white belly and a black tail edge. Their maximum length as adults is 3 metres 10 feet. They measure around 57 to 80 centimetres at birth.
The Galapagos shark can also be found in warm tropical waters at depths ranging from 16 to feet 5 to 60 metres.
Although the Galapagos shark is known to occur around the world, it is commonly encountered where it was first recorded at the Galapagos Islands of Ecuador. The teeth in the upper jaw of this shark are serrated and triangular.
Teeth in the lower jaw are narrower. Galapagos sharks are benthic feeders, meaning they hunt prey from the sea floor, such as fish and octopuses.
Adult Galapagos sharks are also indulge in cannibalism, feeding on their own young if encountered. The Galapagos shark is known to exhibit a threat display of head swinging and exaggerated swimming. They are often found in loose aggregations. Galapagos sharks are pelagic live in open oceans at depths ranging from 16 — feet 5 — 60 metres.
They usually swims in schools. Galapagos sharks are aggressive sharks, there have been reports of attacks on people. Reproduction of the Galapagos shark is viviparous the embryo develops inside the body of the mother, as opposed to outside in an egg.
At birth the 6 to 16 pups are about 22 — 32 inches 57 — 80 centimetres long.Galapagos sharks are curious; they often gather around and bump into boats, oars, divers or anything else that seems to take their fancy.
To rid its stomach of an indigestible object, a shark pushes its stomach out through its mouth, expels the object and then pulls its stomach back into its proper place.
The Galapagos shark, also known as the grey reef whaler, is an aggressive requiem shark that is dark gray on top and has an off-white belly. Its tail has a black edge. There is a ridge running between the dorsal fins (the fins on the shark's back).
The Galapagos Islands is one of the few remaining places in the world where the hammerhead shark can be spotted gathering together in large school of several hundreds.
The main purpose of their scalloped front edge of their hammer shaped head is to improve vision and to provide a larger area for the electroreceptors which the sharks employ for hunting their preys. The Galapagos shark is a type of Requiem shark. These sharks are found worldwide and are mostly seen in wide groups.
They are active predators and are also known as the "Grey Reef Whaler". They are often seen in large groups. It was in the year that Galapagos shark was named from the specimens found near the.
The Charles Darwin Foundation’s Underwater Research The Galapagos Marine Reserve is one of the largest protected reserves in the world, covering a total of , square kilometres branching throughout the archipelago of 13 volcanic islands.
The Galapagos shark is widely seen in tropical oceanic islands that includes Pacific Ocean, Indian Ocean and Atlantic Ocean. Wide population of this species are found in continental waters off the Colombia, Baja California, Bermuda and eastern Australia.
