There are many species of sharks, but the smallest shark in the world is the Dwarf Lanternshark. This shark is only about one inch long. In addition to being the smallest, it is also the most endangered. It is known to only live in a few places on Earth, such as the Mediterranean Sea and the Indian Ocean.
Dwarf lanternshark
The Dwarf Lantern Shark, also called the Etmopterus perryi, is one of the smallest sharks known to man. It is only a little more than 10 cm in length.
This tiny species is found in the Atlantic and Caribbean Seas, off the coasts of South America. Its name comes from the long, flat, head that can be seen in its natural habitat.
Dwarf lantern sharks are found at depths of around nine hundred and fifty-eight feet. They are thought to be a deep-water species, but they have been reported in the shallower waters of the Pacific and Caribbean as well.
These fish are known for their small size and bioluminescent features. They glow at night to attract prey.
In addition, dwarf lantern sharks are known for their slicing teeth. Their lower jaw has thirty-four rows of teeth. The head is long and flat and they have a short, stubby caudal fin.
At birth, a newborn dwarf lanternshark is around 2.4 inches in length. The female can have two or three babies at a time.
Spined pygmy shark
The spined pygmy shark, Euprotomicrus bispinatus, is a small, elongated shark that is found in the oceans around the world. It is one of the smallest sharks in the world and is a member of the family Dalatiidae.
The spined pygmy shark is not threatened. The species lives in deep waters and feeds on squid and crustaceans. They are rarely seen by humans and are not considered a threat to the marine environment.
Although they are relatively harmless, the spined pygmy shark is very common and can be found throughout the world. These sharks are usually found in the Pacific and Atlantic oceans. In the Atlantic, they can be found off southern Brazil, Madeira and Suriname.
The spined pygmy has an elongated body that is black to gray with white tips on its fins. It has an elongated pointed snout with a large spiracle behind each eye. There are 16-21 teeth rows in the lower jaw and 22-31 teeth in the upper jaw.
Granular dogfish shark
Granular dogfish shark is one of the smallest species of sharks in the world. It is found in the Atlantic Ocean around the Falkland Islands. This shark is characterized by its small size and grainy skin texture.
The granular dogfish shark is part of the genus Centroscyllium. Its habitat is in the upper continental slope. Unlike many other sharks in this genus, it has no anal fin. On the dorsal fin, it has a large spine.
Another small and little known shark is the Spined Pygmy shark. This shark has a conical snout, a long second dorsal fin, and a pointed spine on the first dorsal fin. There are two dorsal fins, with the first dorsal fin being larger than the second dorsal fin.
Some sharks have sail-like dorsal fins. Others have conical or tadpole-shaped bodies. However, the majority of sharks have a long snout with an arched mouth. They also have comb-like teeth in the jaws.
African lanternshark
The African lanternshark is a small shark, usually found in deep water. It is part of the Etmopteridae family. They have a unique luminescent glow that attracts their prey and helps them avoid predators.
Their small size makes them difficult to study. They often get caught in commercial shrimping nets. As a result, they are rarely studied. They are considered data deficient by the IUCN. Nevertheless, more research will be needed to discover their true habitat and health status.
They live in waters from 300 to 1,000 meters, primarily off the coast of Africa. They are nocturnal predators. They feed on small fish and squid.
Their eyes are wide and they have a toothy grin. In addition, their jaws have over 60 teeth. Although they are not significant to commercial fisheries, they may be threatened by mortality from bycatch.
Like other species in its family, the African lanternshark uses bioluminescence to attract its prey. It can also use its luminescence to confuse predators.
