Massive Great White Shark caught while Fishing in sea

Sharks are some of the most fascinating and misunderstood creatures on our planet. They have been patrolling the oceans for over 450 million years—meaning they were around long before dinosaurs and have survived five mass extinction events.
Here is a quick look at what makes these "living fossils" so unique:
1. Incredible Biology
Skeleton of Gristle: Sharks don't have a single bone in their bodies. They are elasmobranchs, meaning their skeletons are made of cartilage (the same flexible stuff in your nose and ears), which makes them lighter and more agile.
Sixth Sense: In addition to sight and smell, sharks have "Ampullae of Lorenzini"—tiny pores on their snouts that allow them to sense the electromagnetic fields of other living things. They can literally "feel" a heartbeat in the dark.
Sandpaper Skin: Their skin is covered in "dermal denticles," which are essentially tiny teeth. This reduces drag, allowing them to swim silently and quickly.
2. Diverse Species
There are over 500 known species, ranging from the tiny 6-inch Dwarf Lanternshark to the massive 40-foot Whale Shark.
| Type | Key Fact |
| :--- | :--- |
| Great White | Can maintain a body temperature warmer than the surrounding water. |
| Whale Shark | The world's largest fish; it eats only tiny plankton. |
| Greenland Shark | Can live for over 400 years, making it the longest-living vertebrate. |
| Hammerhead | Their wide heads provide 360-degree vision and better "sweeping" for electrical signals. |
3. The "Jaws" Myth
While movies often portray them as man-eaters, humans are not on the menu.
Rare Attacks: You are statistically more likely to be struck by lightning than bitten by a shark.
Conservation: Humans are far more dangerous to sharks. It is estimated that 100 million sharks are killed every year due to overfishing and finning, leaving nearly 40% of species at risk of extinction.
Sharks are "apex predators," meaning they keep the ocean's ecosystem in balance by weeding out the sick and weak. Without them, the entire marine food web could collapse.
