Females mature about 7.7 ft [2.35 m], and reach a total length of more than 9.8 ft [3 m]. Distribution in the tropical regions of the Pacific Ocean includes Lord Howe Island, Tuamoto Archipelago, Middleton and Elizabeth Reefs, Hawaii, Revillagigedo, Clipperton, Cocos, and Galapagos (Castro, 1983). They can grow to be nearly 12 feet in length. Later that same year, this shark received its currently valid name of Carcharhinus galapagensis (Snodgrass and Heller, 1905).

The pups stay in shallow water nursery areas to avoid predation and cannibalism from members of their own species, eventually moving out to deeper waters as they mature (Compagno et al., 2005). The Galapagos shark can also be found in warm tropical waters at depths ranging from 16 to 200 feet (5 to 60 metres). Long pectoral fins allow it to move swiftly through the bottom of the ocean floor whilst it scouts for prey. The maximum recorded weight is 195 kg (430 lb) for a 3.0 m (9.8 ft) long female. PCL was used to estimate TL based on allometric equations . The Galapagos catshark differs from its congeners in its coloration, the length of its anal-fin base, and in other morphological characteristics. It has a preference for clear tropical waters with strong currents over coral or rocky bottom habitats. The Galapagos horn shark is found in the southern part of the Galapagos Archipelago and along the coast of Peru. The Galapagos shark is brownish-grey upper body and white ventral surface with or without dusky markings on the fins. 17cm. The species name galapagensis is derived from the location, Galapagos Islands Ecuador, where the described specimens were caught in 1905.

Due to its somewhat remote habitat and patchy distribution, the Galapagos shark is of little economic importance. The Galapagos shark displays threat gestures to warn competitors in the search for food (Compagno et al., 2005). And where 99% of them are BIG adult females swimming up to 45+ feet in length! They are found to be present about 31 miles away from the land surface. Their maximum length as adults is 3 metres (10 feet). These sharks have a slender, streamlined body, typical of the requiem sharks. Depth: 10 - 600 ft (3 - 182m). This worm creates a heavy infection that results in the loss of the shark’s scales. As Galapagos sharks reach large sizes, they also feed on other elasmobranchs (Compagno et al., 2005). Galapagos Whale Shark. The genus name Carcharhinus is derived from the Greek “karcharos” = sharpen and “rhinos” = nose. Masks are required at all times. Founded by Jonathan R. Green. Galapagos sharks closely resemble reef sharks and dusky sharks, making them difficult to identify in the field. The Galapagos shark is not as thoroughly studied as many other species and comparatively little is known of its life history patterns. Galapagos sharks are found in aggregations but apparently do not form coordinated schools like hammerhead sharks do in Galapagos. The diving in Galapagos is best known for the BIG and RARE marine life. This parasite can prove to be fatal for the shark (Rand, 1986). They are abundantly present around oceanic islands. So you can get engaged with shark conservation now! There is little information available regarding the utilization of this shark. This species is dominant over the blacktip shark, C. limbatus. This large shark is often confused with several other sharks because of its fin sizes and placements, and brownish grey on top and white underneath coloring. The maximum size for this shark may be 12.1 ft [3.7 m]. Each pup measures 75-89 cm (30-35 inches) in length (Castro, 1983).

When divers took aggressive actions, these sharks were not deterred but instead became more excited (Compagno et al., 2005). Perhaps the most enduring debate in reptile systematics has involved the giant Galápagos tortoises ( Geochelone nigra ), whose origins and systematic relationships captivated Charles Darwin and remain unresolved to this day. The maximum known lifespan is approximately 24 years (Castro, 1983). The very finely serrated lower teeth are symmetrical and erect. Present on coral reefs and rocky outcrops. This shark often swims just above the bottom substrate, forming loose aggregations (Compagno et al., 2005). Male individuals mature at lengths of 6.9-7.5 feet (2.1-2.3 metres), while females mature at 7.2-8.2 feet (2.2-2.5 metres) in length. The maximum weight for this species is 86 kg.

The tall and nearly straight first dorsal fin originates over the posterior third of the pectoral fin inner margin (Compagno et al., 2005). Galapagos sharks pups can be approximately 22 to 32 inches long and a litter can be anywhere from 6 to 16 pups. Although it is considered a coastal species, the Galapagos shark has been reported to cross open waters between islands. This shark is quite abundant in waters around oceanic islands, found close inshore as well as occasionally reported offshore in waters over continental and insular shelves to depths of 180 m (591 feet) (Compagno et al., 2006). Shark bites are extremely rare in Galapagos. It is possible that the Peruvian form is a separate species. Galapagos shark belongs to requim shark family although they are shorter in length than most of their requim family members, their presence can be noted throughout the world along the oceanic island reefs. They have been observed eating or attacking seals, sea lions, marine iguanas, and garbage (Meyer, 2010). Typically, there are 14 teeth on either side of the symphysis in each jaw with one tooth located at the symphysis (Naylor, 1994).

The Galapagos Shark is a common but habitat-limited species, and is normally found at depths of 2 m but ranges to the open ocean adjacent to islands, from the surface to at least 80 m. Juveniles seem to be restricted to shallower waters, with a depth of 25 m or less, which they apparently use as nursery grounds to avoid being eaten by other sharks, while the adults range offshore. 1. This species of shark is highly inquisitive. Here we report a phylogenetic reconstruction based on mitochondrial DNA sequences from Galápagos tortoises and Geochelone from mainland South America and Africa. Prior to attack, the Galapagos shark has been reported to display threat behaviors including arching of the back, raising the head, and lowering the caudal and pectoral fins while swimming in a twisted, rolling motion (Compagno et al., 2005).
