1, hammerhead shark: the earliest evolved hammer-shaped strange head 50 million years ago. Scientists don't know exactly what this unique head shape can do to hammerhead sharks — the greater distance between the olfactory sensors may help them find prey more accurately from them.
2, sword kiss shark: sword kiss shark is very rare, which is not a bad thing for us. The sword-snout shark lives thousands of feet below the surface of the sea and has translucent skin, which gives its body a peachy color. The odd sword-like object on the top of the sword-snout shark's head contains an advanced system of electroreceptors that help them hunt for prey in the depths of the pitch-black ocean.
3, long-tail shark: long-tail shark body length of 20 feet (about 6.096 meters), and the tail accounted for half of the total body length. After observing the long-tail shark predation process, the researchers found that their most common means of swimming through the fish swatting their tails, where the fish were either stunned or shot to death, which was simple and effective.
4, wrinkled shark: deep-sea fish, rarely appear on the surface of the sea, but are often caught by seabed trawls. If you do a closer count, you'll find about 1,000 pointed hook-like structures per gill shark that feed on fish. Of course, this structure may be very primitive.
5. Hard-backed pygmy shark: One of the smallest members of the shark family, the longest body is only 11 inches (about 27.9 cm). Like its close relative, the lantern spiny mackerel, the hard-backed pygmy shark is also a deep-sea fish with numerous bioluminescent organs distributed around the abdomen.
6, albino whale shark: almost all animal species have bleaching phenomenon, sharks are no exception. The albino whale shark in the picture is 33 feet (about 10 meters) long, which is particularly conspicuous on the seabed.
7, sawshark: looks a lot like sawfish, but the former is indeed a shark. Like most sharks, sawsharks have gills on either side of their necks, while sawfish have gills located below their bodies.
8, Greenland shark: Do not be fooled by its name, this shark is as fierce as the great white shark. In fact, during an autopsy of dead Greenland sharks, researchers found the remains of large animals like polar bears in their abdomen, and at one point found the carcasses of entire reindeer, even though the antlers were missing.
9, megamouth shark: giant shark, like whale sharks and basking sharks, are filter food animals, the longest body can grow up to 18 feet (about 5.49 meters), weighing 2.5 tons. Megalomaniacs are deep-sea fish with a ring of luminous organs around their mouths. These sharks are extremely rare, which may come as a surprise given their sheer size.
10. Spiny Tooth Shark: Despite being extinct, the Spinodon Shark is still included in the list of the Top Ten Strange Sharks, mainly because it is perhaps the most bizarre shark on the list. The peculiar jaw of the spiny tooth shark will slowly rotate over time, giving rise to new sharp teeth. The fossil record shows that the shark's biological evolution has been remarkablely successful, reaching its peak between 280 million and 225 million years ago.
