Sharks will never cease to amaze us - from strange and enormous whale sharks to terrifying and magnificent great whites. Even sharks that are not in existence anymore, like the mammoth megalodon, keeps surprising us.
Some individuals are shark lovers, so here are 5 awesome things you need to know about sharks.
1. Shark attacks are (still) occasional
Footage of the moment when a white shark was very close to a surfer in Australia was captured with the help of a drone. The surfer was totally unaware of the shark's closeness and only discovered how close the 5-foot-long (1.6 m) shark was after getting to shore and watching the video the drone captured. Luckily, the shark went away and no one got hurt.
2. Nuclear bombs can help age sharks
The largest fish in the sea are whale sharks, but there are still so many scientists that don't know about the massive creatures, both how long they existed. However, research released this year made a description of how radioactive carbon which are left over from Cold War-era weapon could aid in resolving this mystery.
3. Some sharks can get very, very old
Visualize a shark that was on the seas when the Pope excommunicated Martin Luther and this creature was going strong. There is a possibility that might just be the Greenland shark - Somniosus microcephalus, a dweller of the Arctic that can live centuries - possibly close to 500 years.
In 2016 scientists reported in the journal Science that tests was carried out on the eye tissues of these mysterious sharks and it was discovered that they were centuries old. The method wasn't very exact, so the precise age range came to between 271 and 512 years old.

4. A nude shark?
A shark born with no skin or teeth was kind of existing without inconveniences until fishers trawling the Mediterranean Sea south of Sardinia, Italy, mistakenly cut the mutant fish from the depths. The scary shark was a blackmouth catshark (Galeus melastomus) without skin and teeth.
This infrequent catch is the first and only known instance of a shark existing with a "serious absence of structures that are all skin-related both teeth," as per a study published in the Journal of Fish Biology.
5. An innocent-looking shark with a concealed weapon
Scientists found a lovable, wide-eyed ancient shark with a concealed set of frightening chompers this year. The previously unidentified species, called Ferromirum oukherbouchi, possessed a jaw that usually rotates inward when the mouth was shut, and outward when the mouth was not close.
When this animal opened its mouth, cartilage behind the jaw curved so that the sides of the jaw folded downwards and all teeth, both the teeth still forming in the back, turned upward, letting the shark bite into its victim with as many teeth as possible.
