The ocean is a dangerous place, and animals have to continuously adapt to survive. Sharks have been around for over 400 million years and have had a lot of time to adapt to their environments and lifestyles. Some of these adaptations have rendered sharks downright bizarre. From the shark with the biggest mouth to one with a saw on its head, here are the ten most rare shark species hidden in the ocean!
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 to 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 family's ugly duckling. 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: Basking Shark
The large and monstrous basking shark can grow to more than 10 meters long, making it the second-largest fish in the ocean. It has a huge mouth that can span more than one meter wide. Despite its ferocious appearance, the basking shark is a type of filter-feeding shark and mainly feeds on plankton.
It swims with its mouth open and catches whatever goes through it. When water passes through its gills, the spines of the gill rakers separate the plankton from the water. The shark then closes its mouth and pumps water out through its gills. Each year it sheds and regrows its gill rakers. The basking shark is a migratory fish. They can be found traveling through the Mediterranean Sea, the Pacific Ocean, the Atlantic Ocean, the Sea of Japan, near New Zealand, and Southern Australia, and usually travel in groups of about 100. Its name comes from its habit of swimming very close to the surface with its dorsal fin out of the water - to "bask" means to laze in the sun
Number 8: The Angel Shark
Can a shark be an angel? Well...we leave that for you to chew. But in this case, we don't mean a shark with 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. Compared to most sharks what's unusual about them is their lower tail lobe that extends longer than the upper one.
Number 7: 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 6. Wobbegong
The word "wobbegong" is believed to come from an Australian Aboriginal language, meaning "shaggy beard". It refers to the whisker-like barbels around its nose, and flaps of skin that looks like tiny fins around its mouth and eyes, and on the side of its head. It is mostly found in shallow waters around Australia and Indonesia, usually in bays, caves, rocky bottoms, and reefs.
