Shark Identification, Behavior & Informative Shark Facts

Sharks Of The Hawaiian Waters

Galapagos (Carcharhinus galapagensis) a species of requiem shark, in the family Carcharhinidae, found worldwide. This species favors clear reef environments around oceanic islands, where it is often the most abundant shark species. A large species that often reaches 9-10 ft. Galapagos sharks are active predators often encountered in large groups. Reproduction is viviparous, with females bearing litters of 4–16 pups every 2–3 years. The most commonly seen shark, their behavior is bold, inquisitive and persistent.
Sandbar (Carcharhinus plumbeus) a species of requiem shark and part of the family Carcharhinidae, native to the Atlantic Ocean and the Indo-Pacific. It is one of the biggest coastal sharks in the world, and is closely related to the dusky shark, and the bull shark. Females can grow 6-8 ft and give birth to an average of 8 pups, which they carry for 1 year before giving birth. Males can grow to 6 ft at age 12 years maturity. The longevity of the sandbar shark is typically 35-41 years. Sandbar sharks swim alone or gather in sex-segregated schools that vary in size.
Grey Reef (Carcharhinus amblyrhynchos) a species of requiem shark, in the family Carcharhinidae. One of the most common reef sharks in the Indo-Pacific most individuals are less than 6 ft. They are fast-swimming, agile predators. An aggressive demeanor enables them to dominate many other shark species on the reef, despite their size. They gather in groups of up to 20. They were the first shark species known to perform a threat display, a behavior warning that it is prepared to attack.
Black Tip Reef
Black Tip (Carcharhinus melanopterus) is a species of requiem shark, in the family Carcharhinidae, easily identified by the prominent black tips on dorsal and caudal fins. Among the most abundant sharks inhabiting tropical reefs of the Indian and Pacific Oceans They typically reach a length of 5 ft, and have extremely small home ranges, exhibit strong site fidelity keeping to same local area for several years. Timid and skittish, they are difficult to approach, and seldom poses a danger to humans.
Oceanic White Tip
Oceanic White Tip (Carcharhinus longimanus) is a large 10 ft pelagic requiem shark in tropical warm seas. Stocky body is notable for its long, white tipped rounded fins. Spending most of its time in the upper layer of ocean to a depth of 490 ft they prefer off-shore, deep-ocean areas. Active day and night, swimming style is slow. Despite their habitual isolation from members of their own species, pilot fish, dolphinfish, and remora may accompany them. Known to mariners as “sea dogs” they are commonly ship-following sharks with dog-like behavior when its interest is piqued.
Blue Shark
Blue Shark (Prionace glauca) is a species of large, up tp 12 ft, requiem shark, in the family Carcharhinidae that inhabits deep waters in temperate and tropical oceans. Preferring cooler waters they migrate long distances such as from New England to South America. Generally lethargic, they can move very quickly. Noted for large litters of 25 to over 100 pups. Blue sharks are light-bodied with long pectoral fins. Like many other sharks Blue sharks are countershaded: the top of the body is deep blue, lighter on the sides and the underside is white. A very beautiful shark!
Silky (Carcharhinus falciformis) is a species of requiem shark, in the family Carcharhinidae. Named for the smooth texture of its skin, one of the most abundant sharks in the pelagic zone it can be found around the world in tropical waters. Highly mobile and migratory, this shark is most often found down to a depth of 165 ft. and grows to a length of 8 ft. Females give birth to litters of up to 16 pups annually or biannially. This species often trails schools of tuna, a favored prey.
Thresher are large lamniform sharks of the family Alopiidae found in all temperate and tropical oceans of the world, the family contains four species all within the genus Alopias. Primarily pelagic they prefer the open ocean venturing no deeper than 1,600 ft. Named for an easily recognised exceptionally long thresher-like tail or caudal fin, they are active predators, the tail is used as a weapon to stun prey. Solitary creatures keeping to themselves, they are one of the few species known to jump fully out of the water. Recently listed as vulnerable to extinction by the World Conservation Union.
Smooth Hammerhead
Hammerhead a group of sharks in the family Sphyrnidae, named for the unusual and distinctive structure of their heads which are flattened and laterally extended into a “hammer” shape called a “cephalofoil”, enhancing sensory reception, maneuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters usually swimming in schools during the day becoming solitary hunters at night. Reproduction occurs only once a year, usually a litter of 12 to 15 pups. Red Listed as endangered by World Conservation Union.
Short Fin Mako
Short Fin Mako (Isurus oxyrinchus) avg 10 ft, females up to12 ft. Larger size have darker coloration. Pelagic species found from the surface to depths of 500 ft normally far from land, occasionally closer to shore around island or inlets, inhabits offshore temperate tropical seas worldwide, travels long distances to seek prey or mates. The fastest shark species, speed recorded at up to 46 mph. Bears 4-18 pups on average every 3 years. Intelligent, one of the largest brain:body ratios with exceptional vision. Current record of captive specimen kept alive at NJ Aquarium for only 5 days in 2001.
Tiger (Carcharhiniformes) species of requiem shark, the only member of the genus Galeocerdo. Attains length of up to over 16 ft. Found in tropical and temperate waters, especially in central Pacific islands. Name derives from the dark stripes down its body resembling a tiger’s pattern. Solitary, mostly nocturnal hunter, the Tiger shark is an apex predator having a reputation for eating anything including other sharks and injured whales. Excellent eyesight and acute sense of smell enables it to react to faint traces of blood and follow them to the source. The ability to pick up low-frequency pressure waves enables the shark to advance towards prey with confidence, even in murky water. The shark circles its prey and studies it by prodding it with its snout. Attacking, the shark often eats its prey whole, although larger prey are often eaten in gradual large bites. Often found close to the coast in tropical and subtropical waters throughout the world, its behavior is primarily nomadic, but is guided by warmer currents, it stays closer to the equator throughout colder months. Recorded at depths from 10 ft to 3,000 ft. Females mate once every 3 years birthing 10-80 pups. Attacks by tiger sharks in Hawaiian waters have been shown to increase between September and November, when tiger shark females are believed to migrate to give birth.
Great White
Great White (Carcharodon carcharias), is a species of large lamniform shark which can be found in the coastal surface waters of all major oceans. The Great White is mainly known for its size with mature individuals growing in excess of 20 ft in length. Lifespan is estimated to be as long as 70 years or more, making it one of the longest lived cartilaginous fish currently known. They can accelerate to speeds that exceed 35 mph. With no natural predators other than the Orca, it is arguably the world’s largest known extant macropredatory fish, and is one of the primary predators of marine mammals. To more successfully hunt fast and agile prey such as sea lions, the Great White has adapted to maintain a body temperature warmer than the surrounding water. They can detect the electromagnetic field emitted by the movement of living animals, when a living creature moves, it generates an electrical field and Great Whites are so sensitive they can detect half a billionth of a volt. Even heart beats emit a very faint electrical pulse. If it is close enough, the shark can detect even that faint electrical pulse. They have been tracked traveling for thousands of miles, and diving to depths up to 3,000 ft. The reasons for their migration is still unknown but possibilities include seasonal feeding or mating. Almost nothing is known about the reproduction of Great Whites. Great White sharks do not survive in captivity.

Shark Teeth Diagram

PLEASE do not buy sharks teeth jewelry made from shiny white sharks teeth! Many sharks are illegally harvested for their jaws & teeth and you will know a tooth is “new” if it is shiny white. A black, brown or tan colored tooth is “fossilized” meaning it was found, rather than harvested. Only purchase darker colored shark teeth jewelry! Thank you, From the Sharks!
