The rare goblin shark is known as a “living fossil” because the species was once thought to be extinct and its body has evolved only minimally in more than 125 million years. The most special feature of this deep-sea shark is its long snout and strange teeth, which look like alien creatures. According to Smithsonian Ocean, goblin sharks’ teeth can expand rapidly to help them ambush and catch prey, a technique called slingshot catching.

Shark cuts the cake

The name of this species sounds cute, but this is actually a quite scary shark. Cutter sharks are only about 42 – 56 cm long. They feed by attaching their lips to prey, including white sharks, then pinning their sharp teeth into the prey’s flesh and rotating around to leave a deep pit wound. This is not a small wound, as there are recorded wounds about 5 cm wide and 7 cm deep.

Because they live in the deep ocean, this species rarely encounters humans; However, in Hawaii, a long-distance swimmer was reported to have been attacked while swimming between islands.

Sunbathing shark

The basking shark is the second largest extant fish after the whale shark, and the second of the three plankton-eating sharks, along with the whale shark and the megamouth shark. This is an internationally migratory species found in all temperate oceans of the world.

Basking sharks are found from depths of at least 910 m. Their length can be up to 13,716 m, and it weighs about 19 tons. Despite their giant size, they are not necessarily an aggressive, scary predator. These sharks eat passively, by swimming with their mouths open. As water passes through the gills, plankton is retained; A fairly large shark can filter about 1,500 m3 of water per hour.

According to Oceana, the gestation period for female basking sharks is about 3 years.

Carpenter shark

Carpenter sharks are also known as sawfish, their scientific name is Pristiformes , a fish related to sharks and rays. A special feature is that their long flat snout resembles the shape of a saw blade, the “teeth” protruding from the snout are not real teeth, but they are modified tooth-like structures, called teeth. “denticle”. The sawfish twists its long snout to stun its prey, then uses its mouth to eat.

Dwarf lantern shark

As its name suggests, the dwarf lantern shark has two distinct characteristics: its small size and the ability to glow in the dark.

This species is rarely seen and little studied, and is believed to live off parts of the northern coast of South America. It is the smallest known shark on Earth, measuring only about 15 meters. – 20 cm. Photophores, light-emitting organs, are scattered along their fins and abdomen and act as decoys in deeper, darker waters and also as camouflage in shallower sunlit areas sun.

Frill shark

The frilled shark is shaped like an eel and lives in the Atlantic and Pacific oceans. They are so named because they have 6 pairs of gill slits like prehistoric sharks and are famous for their terrifying bites, with a mouth with 300 teeth arranged in 25 rows.

The frilled shark is a species of shark belonging to the genus Chlamydoselachus , living mainly in waters about 1,500 m deep. They carry some characteristics of their primitive shark ancestors, dating back 80 million years, and are called “living fossils”.

“The teeth are designed to hold tightly, and from their special shape and sharpness, it seems that nothing can get in but can escape,” Zoologist Samuel Garman wrote about the mouth. fear of this shark in 1884.

Spotted Wobbegong shark

Spotted Wobbegong sharks live at night in shallow waters such as around caves and coral reefs in the Eastern Indian Ocean, the South China Sea as well as off the coast of Queensland, Australia or possibly even Japan.

The fleshy spots and tentacles help them almost completely blend in with their surroundings so they can easily attack octopuses, crabs, sea bass, etc. According to Georgia Aquarium, Wobbegong is an Australian aboriginal word and is speculated to mean “living rock”.

Sharp-nosed blue ghost shark

The ghost shark, also known as chimaera , is a rare blind fish with wing-shaped fins. Related to sharks and rays, ghost sharks diverged from these genera 300 million years ago. Sharpnose blue ghost sharks were first seen swimming in the wild in 2016. It is known that this species lives in the Southern Hemisphere but according to recent observations, they appear in the Pacific Ocean near California and Hawaii.

Unlike many other famous sharks, ghost sharks do not have jagged teeth but chew foods such as krill and insects with mineralized dentures. The lateral lines on their head and face contain sensory cells that allow the animal to sense movement in the water and locate prey.
