It prefers deep sea habitats, below 90 meters. This makes it one of the highly migratory marine species. The Sixgill is one of the widest ranging sharks, inhabiting continental as well as island shelves of the world’s temperate and tropical seas. The Bluntnose (H.griseus) is the largest of the two species, growing up to 4.8 meters long and weighing 580 kilograms. The dorsal fin is positioned close to the tail. Bluntnose Sixgill Shark - 15.8 FeetĪ member of the Hexanchidae family, the Bluntnose Sixgill Shark is a deep-sea predator characterized by six pair of gill slits on either side of its broad head, a long tail and comb-like yellow teeth. They can be found close to the shore as well as in the open seas. These sharks inhabit tropical as well as temperate waters. Male Bigeye Thresher sharks mature at about 3 meters while females mature at 3.5 meters. The shark has greyish-brown or purplish-grey coloration skin with light grey underneath. This long curving, upper tail lobe is nearly as long as the entire fish’s body. Scientifically known as Alopias superciliosus, bigeye Thresher Sharks are identifiable by their characteristic long, whip-like tails. They belong to the superorder Selachimorpha and modern sharks are characterized by features such as five to six pairs of gills, a cartilaginous skeleton, and multiple rows of teeth. With over 460 known species, sharks have longtime dominated the world's oceans. They called that shark ″Big Daddy.″ 2.The World's Largest Sharks The hammerhead shark is one of the world's most iconic. Mundus harpooned a 4,500-pound shark in 1964, the largest ever on the East Coast, but sharks that are harpooned are not considered for world’s records. The book and movie ″Jaws,″ about a massive shark terrorizing a Long Island town, were based in part on Mundus’ experiences. Mundus is Montauk’s most famous shark killer. He is a shark-hunter, believed by many - particularly Mundus - to be the inspiration for Quint, the shark-obsessed waterman played by Robert Shaw in the movie “Jaws.” The shark, caught on a 150-pound test tackle normally used to catch giant tuna, was said to be 800 pounds heavier than the previous record for a great white shark that was caught, as listed in the Guinness Book of Records. great white which we caught commercially by harpoon in 1964 to him. Mexico’s Great White SharkĪccording to a website dedicated, the biggest shark Frank Mundus, a legendary captain with a habit of catching giant sea creatures, ever caught was a 4,500 lbs. It was Monday morning before the fish could be put on a certified scale where it weighed in at 1,780 pounds, 13 feet, 10.5 inches long, shattering the International Game Fish Association World Record by 300 pounds. His friends were able to secure it with a gaff and heavy rope while waiting for a wrecker to hoist it onto a flatbed truck. Maxwell vowed to those who had gathered that he would stay on the pier night and day, if necessary, to get another chance at the giant fish. After almost five hours of fighting the fish, Maxwell got the tiger shark next to the pier for the last time. Local angler, Walter Maxwell, had fought it for hours, bringing the shark so close he could almost touch it-and then, just as the monster fish reached the pier, the line broke. On Saturday, June 13, 1964, onlookers who had gathered at the Cherry Grove fishing pier watched in disbelief as the biggest tiger shark they’d ever seen slowly swam into view. This is the reason why a sawfish gets flipped over when scientists work on them in water. It comes as a shocking surprise that sharks can go without eating for a whole six weeks! One such record was made by a swell shark, which did not eat for a massive 15 months! When a shark flips upside down, they go into a state of trance which is known as tonic immobility. This is because the back of a shark’s eyeball has a reflective layer of tissue called tapetum which helps them see well with little or no light. Considered ocean’s top predators, these sharks can see very well even in the darkest places of the ocean and possess incredible night vision. They have different diets and behaviours. Sharks have more than 500 species and they come in all different shapes and sizes and colours. If scientists are to be believed, these sharks have been around for over 400 million years! Numerous movies have been made on sharks and how they are blood-sucking villians, but in reality, they are far more interesting and gentle creatures.
