Taxonomy
Description
The Galápagos shark is a large shark species, averaging about 10 feet in length. Its body is streamlined like most reef sharks and its coloration ranges from dark gray to light gray on the dorsal side and whitish on the ventral side.
The Galápagos shark features a tall, rounded first dorsal fin followed by a smaller second dorsal fin. Its caudal fin is asymmetrical with the upper lobe larger than the lower lobe.
The Galápagos shark has a robust upper jaw dentition with broad, triangular teeth effective for catching prey.
Range
These sharks are primarily found in the eastern Pacific ocean, particularly around the Galápagos islands, from which they get their name. They are also present in other regions of the Pacific ocean, such as the west coast of Mexico and the Revillagigedo archipelago.
Habitat
The Galápagos shark is a reef shark that frequents the coastal waters of oceanic islands off Central and South America. It is notably abundant around the
Galápagos islands which gave it its name. However, the Galápagos shark is also widely distributed across the world's seas and oceans in waters near coral reefs or continental slopes.
The Galápagos shark can be found at depths of up to about 920 feet.
Diet
This shark is a nocturnal hunter with a diet that includes a variety of prey such as bottom-dwelling fish, cephalopods including squid and octopuses, and crustaceans.
Reproduction
The Galápagos shark is a viviparous species that typically reaches sexual maturity around 8 to 10 years of age for females and 6 to 8 years for males.
After a gestation period of about a year, the female gives birth to a litter of several baby sharks with the number varying up to around fifteen.
