[10] In temperate seas it may approach shore, where it can be observed by divers; while in tropical waters, it inhabits greater depths. BluShark is a brand of premium nylon, silicone, and leather watch bands. Browse through our category-defining blue shark size products in a simple, secure, and faster way. The blue shark (Prionace glauca) is a species of requiem shark. The courtship ritual includes the male biting the female, so one way to sex a blue shark is to look for the bite scars always found on mature females. Males mature at 4-6 years: females at 5-7.

When in the tropics, the shark usually swims to deeper water with cooler temperatures. [18], Blue sharks are relatively easy to feed in captivity, and the three primary issues appear to be transport, predation by larger sharks and trouble avoiding smooth surfaces in tanks. [10] In temperate seas it may approach shore, where it can be observed by divers; while in tropical waters, it inhabits greater depths. These sharks are most active in the early evening and at night when they may move inshore. Blue Shark Facts: Size, Habitat, Reproduction. Their meat is low of value, but their large, valuable fins are kept and enter the international shark fin trade (often after the carcasses are discarded at sea). An unusual case was a mother that had 130 pups, but the average amount ranges between 25 and 50. BEHAVIORBlue sharks cruise slowly at the surface with the tips of their dorsal and tail fins out of the water, and long pectoral fins extended. The shark is found worldwide in temperate and tropical waters. There is a report of high concentration of heavy metals (mercury and lead) in the edible flesh. In the eastern Pacific, Blue sharks range from the Gulf of Alaska to Chile. Upon accepting, the male inserts its clasper into the female’s oviduct and transfers the sperm to fertilize the eggs. [3], The blue shark is an oceanic and epipelagic shark found worldwide in deep temperate and tropical waters from the surface to about 350 m (1,150 ft). Like other requiem sharks, blue sharks do not do well in captivity. SIZE At birth, the shark is 1.1 to1.4 ft [35 to 44 cm] in length. Some countries have banned shark finning, but still, there are not international treaties linking all aspects of blue shark protection. Also, blue sharks are eaten by other species of sharks if they are housed together. It becomes infected by eating intermediate hosts, probably opah (Lampris guttatus) and/or longnose lancetfish (Alepisaurus ferox). [4], They are very opportunistic when it comes to hunting. It has extremely long, pointed pectoral fins, which are usually as long as the distance from its snout to the front of its gill slit. [18] Small blue sharks, up to 1 m (3.3 ft) long, are relatively easy to transport to aquariums, but it is much more complicated to transport larger individuals. In the western Pacific they are found from Japan to New Zealand. Males mature at 6 to 9.2 ft [182 to 281 cm], while females mature at about 7.2 ft [220 cm].

Female sharks have adapted to the behavior by having skin that is three times thicker than that of male sharks. The second dorsal fin measures almost half the size of the first and its pectoral fins are unusually long compared to other sharks. This species presents slight sexual dimorphism since the female tends to measure little more than 1 meter in comparison with the male. In contrast to other shark species, the blue shark is not a regular victim of commercial fishing although it is usually caught by fishing nets incidentally. It inhabits the epipelagic and mesopelagic zones near the coasts and the continental shelves, but if it dwells tropical waters, then it tends to go towards deeper waters. Blue sharks give birth to large litters, ranging from as few as four pups to as many as 135. Although often timid, they are potentially harmful due to their dentition, and have been implicated in a few accidents. Blue sharks are light-bodied with long pectoral fins. [18], In June 2018 the New Zealand Department of Conservation classified the blue shark as "Not Threatened" with the qualifier "Secure Overseas" under the New Zealand Threat Classification System. Possibly the most wide-ranging of sharks because they live in such a broad range of areas. Blue sharks live to up to 20 years. [3], The blue shark has one of the largest ranges in terms of depths of the water. The upper teeth in the blue shark's mouth are distinctive. Blue sharks segregate by age, sex, and reproductive phase: juveniles, sub-adults, mature sharks, and pregnant females are usually found in separate areas, with adult males and females meeting only briefly to mate. The frequency which females give birth or the time that the deposited sperm is stored after the intercourse is still uncertain, but the blue shark migrates northward to deliver their offspring. From 1580 up until 2013, the blue shark was implicated in only 13 biting incidents, four of which ended fatally. Deep Blue played a role in the Discovery Channel’s 2014 Shark Week when she was tagged by experts. Recent reports of approximately 60-80% decline in catch rates and reductions in sightings frequency, but data are inadequate to assess global population decline. The gestation period is between nine and 12 months. [12] The blue shark can swim at fast speeds, allowing it to catch up with prey easily. [16] The skin is used for leather, the fins for shark-fin soup and the liver for oil. Blue Shark Size: These sharks do not grow up so long as the Whale shark. Males mature at 6 to 9.2 ft [182 to 281 cm], while females mature at about 7.2 ft [220 cm]. However, a few unusually large specimens have been documented. Occasionally, an outsized blue shark is reported, with one widely printed claim of a length of 6.1 m (20 ft), but no shark even approaching this size has been scientifically documented.
