It is found in all the same areas at similar depths ~4000 feet. Most of the information is partial, and deduced from the morphology of the shark and from samples of the few existing specimens. Since it seems to feed on migratory fish, it is probably active in the evening and/or morning when the migrations are going on, but there are no direct accounts of feeding times. The truth is that most sharks are carnivorous and efficient predators, although some others feed on plankton. Stephen Bizer (author), University of Michigan-Ann Arbor, Phil Myers (editor), Museum of Zoology, University of Michigan-Ann Arbor.

Like all sharks, goblin sharks probably hunt using their senses of smell, sight, sound and the electrical sensing organs called ampullae of Lorenzini. Because they are so slow moving, scientists believe these sharks are ambush predators. Bottom habitats in the very deepest oceans (below 9000 m) are sometimes referred to as the abyssal zone. This is probably not different in the case of the goblin shark. This material is based upon work supported by the (Duffy, 1997; Martin, 1999), Goblin sharks seem to live in the mid and deep-water zones of outer continental shelves and slopes. (Compagno, 1984; Duffy, 1997; Martin, 1999; Rorem, 2002), Mitsukurina owstoni appears to feed mid-water or close to the bottom where it uses a combination of electrical sensors, smell and (minimal) eyesight to catch any vertically migrating animals that it comes across.

(Berger, 1987; Compagno, 1984; Duffy, 1997; Martin, 1999; Rorem, 2002), Mitsukurina owstoni develop directly from birth, and are probably ecologically similiar to free-swimming adults when they emerge from the mother. It has the motive - appetite for anything that moves. Another way allele frequency can change is through the migration of a group of individuals from one population to another. Another theory has goblin sharks actively hunting for benthic prey using electroreceptors on its enlarged snout (similar to hammerhead sharks) and using this snout to dig up any prey it detects underneath the sand. (Martin, 1999). It is not known at what age they become sexually mature, but are immature to about 2.3 m. (Martin, 1999). U.S. ESA. (Martin, 1999), Due to its morphology, it is assumed that Mitsukurina owstoni is rather sluggish and accomplishes most of its hunting by swimming lazily or waiting for vertically migrating animals to come within striking distance. The Goblin Shark uses the ability to sense prey with electro sensitive organs of the snout when they aren’t able to see well in the depth of the water where they live. “The Goblin Shark, the ugliest being in the planet.

In 1985, it was discovered in the waters off eastern Australia. Allele frequency can change with a couple of different processes. Advertisement. When prey is just out of reach, the shark extends the elastic tissue out of the mouth to nab the grub. Natural selection is a well known theory developed by Charles Darwin. "Biology of Sharks and Rays: Biology Of the Goblin Shark (Mitsukurina owstoni)" Essentially all known data on goblin sharks are from accidental catches in trawling nets. having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature. National Science Foundation As of now, there is only one recognized species. This peculiar species has done so by greatly elongating and flattening its nose so it can be used for protection and hunting prey. IT CAN GET BIG. 4 Sharks of the World.
