The average lifespan of the shark is about 36 years. A black scabbardfish (Aphanopus carbo) fishery off Madeira also takes two or three goblin sharks annually. However, there was a capture of an extra-large Goblin Shark which was estimated to be measuring 5.4 to 6.2 m (18 to 20 ft).

The Goblin Shark Is not as Scary as It Looks. [5][7][20], The body is fairly slender and flabby. [9][10] Studies using genetic data have also confirmed a basal classification for this species. One of the significant differences between them and other species of sharks is the appearance of their fins. The long, flat snout that the Goblin Shark has will actually decrease in length proportionally with age. So can this goblin shark Kill this swimmer Short answer, the average swimmer have like a 0.00000001 chance of even encountering a goblin shark even less of the goblin attacking the human. Only one extant species (Mitsukurina owstoni) is known, on the basis of a few specimens, although fossils of extinct species have been found.The goblin shark is closely related to the sand shark.Although captured sporadically worldwide, most specimens have been taken from deep marine waters near Japan. The five pairs of gill slits are short, with the gill filaments inside partly exposed; the fifth pair is above the origin of the pectoral fins. [1] However, during June 2018 the New Zealand Department of Conservation classified the goblin shark as "At Risk – Naturally Uncommon" with the qualifiers "Data Poor" and "Secure Overseas" using the New Zealand Threat Classification System. [17] As the last member of an ancient lineage, and one that retains several "primitive" traits, the goblin shark has been described as a "living fossil". All teeth vary in length and width throughout the massive number of rows. They have a protruding jaw with sharp tiny teeth that are arranged in multiple rows and a long and flat snout that resembles a sword blade. The shark has the pink color on its body. [5] Yet unlike most deep-sea sharks, it can change the size of its pupils, thus probably does use its sight in some situations. The Goblin Shark had striking similarities to the shark fossils from the Scapanorhynchus species that lived almost 100 million years old. The cause of the incident is unclear although recent earthquake activity in the region may have contributed to the mass appearance of the Goblin Shark, which would have been a rather rare occasion. Eventually, more complete fossils revealed many anatomical differences between Scapanorhynchus and Mitsukurina, causing modern authors to again regard them as distinct genera. Goblin shark size makes it grow to a length of at least 12.5 feet (3.8 meters), has a body and soft skin that, in life, is of a pinkish-gray color. [15][16] Striatolamia macrota, which lived in warm shallow waters during the Paleogene period (c. 66–23 Ma), may also be a Mitsukurina species. [18], The goblin shark has a distinctively long and flat snout, resembling a blade. It is most active in the morning and the evening. [25] Goblin sharks may be the prey of blue sharks (Prionace glauca). [26] Parasites documented from this species include the copepod Echthrogaleus mitsukurinae,[31] and the tapeworms Litobothrium amsichensis and Marsupiobothrium gobelinus. A chameleon’s tongue can be as long as its body. [7][20] The soft, semitranslucent skin has a rough texture from a covering of dermal denticles, each shaped like a short upright spine with lengthwise ridges. Retrieved November 29, … This means there would be small litter sizes and that the embryos would grow during gestation. [35] This “slingshot” style of feeding could be an adaptation to compensate for poor swimming ability by allowing the goblin shark to catch elusive, fast prey without having to chase the prey. Little is known about goblin shark reproduction because a pregnant female has yet to be found and studied. They arent pointed but instead they are round and they are lower on the body. Goblin Sharks have been found at depths from 270 m to as deep as 1300 m (890 ft to 4300 ft). The goblin shark’s years of solitude down in the dark depths of the ocean have made for quite the elusive species. Named for its peculiar, blade-like snout and toothy, forceps-like jaws, the Goblin Shark (Mitsukurina owstoni) is arguably the weirdest of sharks. It has a long, prominent snout covered with special sensing organs (ampullae of Lorenzini) that help it to sense electric fields in the deep, dark water it calls home. Atlantic, Pacific & Indian Oceans. The experts believe that this has to do with the … (2016, August 11). Named for its peculiar, blade-like snout and toothy, forceps-like jaws, the Goblin Shark (Mitsukurina owstoni) is arguably the weirdest of sharks. Averagely, an old Goblin Shark grows to a length of 3.8m (15.2ft). Sadly, there has been evidence of Goblin Sharks eating garbage that is found near the ocean floor – the natural habitat of this water creature. They also have pelvic fins that are quite a bit larger than their dorsal fins. Fishing Goblin Sharks will also contribute to this as they have become quite valuable to collectors. "We understand that on … In fishery numbers, stray Goblin Sharks are caught but not in huge numbers. Longevity. [2] Goblin sharks are benthopelagic creatures that inhabit upper continental slopes, submarine canyons, and seamounts throughout the world at depths greater than 100 m (330 ft), with adults found deeper than juveniles. This pink-skinned animal has a distinctive profile with an elongated, flat snout, and highly protrusible jaws containing prominent nail-like teeth. But most commonly found off the coasts of Japan. The fins' margins are translucent gray or blue, and the eyes are black with bluish streaks in the irises. Shark lifespan vary by kind and it is very different for each of them. [7] It has been caught as deep as 1,300 m (4,300 ft), and a tooth has been found lodged in an undersea cable at a depth of 1,370 m (4,490 ft). While no pregnant sharks have been found to be studied, scientists believe their reproductive habits are similar to other mackerel sharks. Some researchers believe that these sharks could also dive to depths of up to 1,300 m (4,270 ft), for short periods of time.[2]. Goblin Shark Reproduction and Lifespan. American ichthyologist David Starr Jordan described the goblin shark in an 1898 issue of Proceedings of the California Academy of Sciences, recognizing the peculiar fish not only as a new species, but also a new genus and family. Life of Sea | Goblin Shark (Mitsukurina owstoni) | Goblin shark is a deep-sea shark, the only living species in the family Mitsukurinidae. [1][26] On 19 April 2014, fishermen in Key West, Florida, while fishing in the Gulf of Mexico, caught a goblin shark in their fishing net, only the second one ever to be caught in the Gulf. It likely shares the reproductive characteristics of other mackerel sharks, which are viviparous with small litter sizes and embryos that grow during gestation by eating undeveloped eggs (oophagy). This rare species of deep-sea shark is called the Goblin Shark (Mitsukurina owstoni). In fact, you would be right if you said the Goblin Shark was a bottom feeder as most of its food comes from the sea floor and the middle of the water column. The most striking characteristic of the Goblin shark is the unusual shape of his head. [1] No data is available concerning growth and aging. Sometimes called a "living fossil", it is the only extant representative of the family Mitsukurinidae, a lineage some 125 million years old. While no pregnant sharks have been found to be studied, scientists believe their reproductive habits are similar to other mackerel sharks. Adults are known to inhabit the deeper waters than juveniles and there have been reports of the odd Goblin Shark found in shallow inshore waters of 130 feet. Its jaws can project open quickly in order to catch prey. The protrusion of the jaw is assisted by two pairs of elastic ligaments associated with the mandibular joint, which are pulled taut when the jaws are in their normal retracted position; when the shark bites, the ligaments release their tension and essentially "catapult" the jaws forward. Fish, such as rattails and dragonfishes as well as cephalopods and crustaceans. The Goblin Shark has been caught in depths of between 890 and 3,150 feet and as deep as 4,300 feet. Some other distinguishing features of the shark are the color of his body, which is mostly pink, and its long, protrusible jaws. [35] What makes the goblin shark unique is the kinematics of their jaw when feeding. This allows the animal to chow down on snacks such as teleost fish and squid. While many types live 20 to 30 years in the wild, there are some types that live much longer than others. [32], The goblin shark feeds mainly on teleost fishes such as rattails and dragonfishes. The pectoral fins are also rather small and rounded. Its low-density flesh and large oily liver make it neutrally buoyant, allowing it to drift towards its prey with minimal motions so as to avoid detection. [7], The goblin shark has been caught in all three major oceans, indicating a wide global distribution. A full grown Goblin Shark will be from 8 feet to 12 feet in length, with females usually being larger than the males. For an average sized Goblin Shark, is weight is estimated to be 210 kg (460lb). [7] Several goblin shark specimens were described as separate species from 1904 to 1937, none of which are now considered valid. The goblin shark (Mitsukurina owstoni) is a rare species of deep-sea shark. The goblin shark has a re-opening and re-closing pattern during the strike, a behavior that has never been seen in other sharks before and could be related to the extent with which the goblin shark protrudes its jaws. [22][23] In the Indo-Pacific and Oceania, it has been found off South Africa, Mozambique, Japan, Taiwan, Australia and New Zealand. It is the only living member of the Mitsukurinidae family, and it is often called a “living fossil” since its ancestry goes back to the Cretaceous period and it keeps such primitive characteristics.It was given a scientific name in honor of two people who collaborated in its discovery in the late nineteenth century: Kakichi Mitsukuri and Alan O… This shark comes from the Mitsukurinidae family, a family of sharks that date back over 125 million years. These species were considered long extinct, and discovering them felt as if they walked straight out of the grave. The jaws are very protrusible and can be extended almost to the end of the snout, though normally they are held flush against the underside of the head. The International Union for Conservation of Nature (IUCN) has assessed it as Least Concern, despite its rarity, citing its wide distribution and low incidence of capture. They particularly like crustaceans, cephalopods and teleost fish. [1] In addition to its wide range, most of its population is thought to reside in unfished environments because few adults are caught. [27] The shark was photographed and released back into the water. maslinensis. Due to the fact that this is not a very fast swimmer, with poor eyesight, the Goblin Shark has devised a hunting method that has been described as ambush predatory.
