The Great whites and the tiger sharks fill our imagination anytime we think about sharks. And the reason is quite obvious. We hear of them every time, and we know them as predators ready to attack whenever they get the chance. Because of that, the word "shark" has become so mundane that it has lost his scientific value. But little did we know that the great whites are just a few out of thousands out there. And for many of those sharks, scientists and marine experts themselves find it difficult to fully understand them because they're the rarest of the rare.

From the megamouth shark to the goblin shark to the long-tailed thresher shark to the angel shark and to a shark that has existed for 300 million years, welcome to an oceanic FactFile's top ten list of the rarest shark species hidden in the deep!

Number 10: The Goblin Shark

If there's at least one thing, you don't want to come across while diving in the ocean, it's a goblin shark. But to meet one, you should be ready to dive at least 3,000 feet within the deep. So, a real-life encounter with a living one in the waters is next to impossible. But less than 50 of them have been spotted in major oceans of the world, particularly by pelagic longlines and cameras. If not for those things, we'll never know they exist. And till date, no one knows how they survive at such depth or how they reproduce because a pregnant female has never been caught.

As for the looks, Goblin sharks are so ugly that many people call them the ugly duckling of the family. And with a freaky long nose, an extendable mouth plus a see-through skin that reveals their underlying blood vessels, we think they're even compassionate. Their pinkish skin fitted with two spooky blue-black eyes would make most people pray they always remain hidden in the deep, never to see the light!



Number 9: The Thresher Shark

Thresher sharks reside in all temperate and tropical oceans of the world except the Central and Western Pacific. But to see one up close, you've got to prepare for a dive of about 1500 feet at depths where you can only imagine your worst nightmares. Once you’re there, a couple of other sharks would welcome you. But if any other shark is going to catch your attention aside from the great whites, the thresher shark is amongst them. With a tail the size of their body, it's rare for anyone to miss them. That tail, however, was a long mystery for the science world until rare footage about what they were used for popped up in 2013. As it turned out, thresher sharks use their tail like a whip, primarily for hunting small fish. They slap it across a school of fish to knock several unfortunate fish dead in an instant. But even with such epic hunting skills, thresher sharks are still classified vulnerable to extinction! The major reason: they have a low reproductive window of just 6 years before dying.



Number 8: The Dusky Shark

Also known as black whalers, dusky sharks are reputed for their long seasonal migration and their abilities to swim in all oceans worldwide. Either warm or cold, they take no preference in the waters they reside in. But they're known to migrate from the part of the ocean where temperatures become too unbearable. For instance, most dusky sharks move towards the pole in summer and travel up to 2,000 nautical miles back to the equator when winter is around the corner. Because of that, dusky sharks are considered to be generalist apex predators that can feed on many things on their menu. They can grow to a size relative to a 6-foot man, weigh twice as much, and live up to a jubilee. On that basis, we can say they're a successful species.

However, their major problem is their reproductive cycle, which takes about 20 years to attain sexual maturity with another 22 months for a female to give birth. But within this period, a dusky shark might have fallen victims to men who target them for their precious fin. Thus, they're incredibly rare and endangered.



Number 7: The Angel Shark

Can a shark be an angel? leave that for you to chew. But in this case, we don't mean a shark with the wings plus a halo on its back. Instead, we refer to a very rare species of shark notable for their flattened bodies and head. Though they resemble a stingray very much, their dorsal and caudal fins make them very different. Angel Sharks have five gill-slits on their backs and two dorsal fins. Both pectoral and pelvic fins are still intact. And all that makes them more sharks than any other. What's unusual about them compared to most sharks is their lower tail lobe that extends longer than the upper one.
