Hello and welcome to our presentation about one of the most enigmatic and scariest ocean animals: the shark.
Today, Adam and I will share some of the most interesting facts about them.
How old are sharks?
Sharks have been around for more than 400 million years, since the time of the dinosaurs.
Where do sharks live?
They can live in almost any ocean habitat, even in some rivers and brackish waters.
How big are sharks?
There are more than 500 species of sharks.
They come in all shapes and sizes.
From the small pygmy shark with a size of less than a foot to shark to the massive whale shark. The whale shark is the biggest shark and fish in the world. It can grow to 40 feet long and weigh up to 20 tons.
Do sharks have a sixth sense?
Sharks have a sixth sense called electroreception that allows them to detect the electrical fields produced by other animals, even in complete darkness.
They have a fantastic sense of smell paired with excellent vision. With these tools, sharks can sense and see their prey long before their target suspects anything.
How and where do sharks live?
Sharks are a group of animals that have adapted to live in a wide range of marine environments, from shallow coral reefs to the deepest parts of the ocean. Many shark species are apex predators, which means they are at the top of the food chain in their ecosystem. They are streamlined, fast-swimming predators with a keen sense of smell, excellent vision, and specialized electroreceptors that allow them to detect electrical fields generated by other animals.
Who are the sharks’ biggest rivals?
Sharks are at the top of the ocean’s food chain, but even they fear one ferocious animal – dolphins!
Although the dolphins look innocent, they can be fierce and successfully eliminate sharks. Even the great white. To know more about it check our article: Top Facts about Dolphins.

How many teeth do sharks have?
Sharks can grow more than 30,000 teeth in a lifetime, depending on the species. Some species can replace a tooth in as little as seven days. Sharks have multiple rows of teeth in their mouths at any given time.
Do sharks live in rivers?
Some sharks can live in rivers. Glyphis, also called river sharks, are a group of sharks that live in rivers and along the coasts of southeast Asia and parts of Australia. They are rare and hard to find.
The bull shark is another type of shark that can live in salt and fresh water. It can swim up rivers and has a reputation as a dangerous predator. The bull shark is known to attack any prey it can reach, humans included.
Do sharks have eyelids?
The majority of sharks don’t have eyelids. When they attack, they roll their eyes at the last second to protect their eyes from damage.
Do sharks have bones?
The mighty sharks do not have bones! Instead of bones, sharks have lightweight cartilage, which forms a skeletal structure. Cartilage is a material similar to the hard part of our ears.
Even sharks’ teeth are not made of bones!
Nor the shark’s teeth are attached to their jaws, but to their gums. Shark teeth are made of dentine, solid and similar material but not the same as bone.
Can sharks travel long distances?
Some sharks migrate long distances each year, swimming up to 20,000 km or 12427 miles between feeding and breeding grounds.
Are sharks dangerous to humans?
While sharks are frequently portrayed as mindless fearsome predators, the truth is that they are rarely a threat to humans. In reality, the chances of getting attacked by a shark are very low.
Sharks tend to be curious about humans, and some have playful interactions with them.
Some, like the nurse shark, are pretty harmless, and humans can get near them without considerable risk of getting hurt.
But some, like the bull shark, tiger shark, and great white shark, are known to be more aggressive than others.
Most shark attacks happen when a shark misidentifies a human as its natural prey, such as a seal or a fish.
The best thing to do is to stay as far as possible from the areas where they live and feed.
What are the most dangerous sharks?
The Great White Shark, Tiger Shark, Bull Shark, and Oceanic Whitetip Shark are the most dangerous. These sharks can be very aggressive and dangerous to humans.
The Great White Shark can live more than 70 years, grow more than 26 feet (6 meters), and weigh 5.000 pounds (2.268 Kg).
Tiger shark has a lifespan of 50 years, a length of 17 feet (4.5 meters), and weigh 1.400 pounds (630 Kg).
Oceanic Whitetip Shark lifespan is 16 years, length of 13 feet (4 meters), and weight 370 pounds (170 Kg).
Can sharks hear?
Even though sharks don’t have external ears, they have an excellent sense of hearing that lets them hear sounds from hundreds of yards away, which helps them find their prey and navigate around.
Are sharks important for the ocean ecosystem?
They are critical to maintaining the health of marine ecosystems by cleaning the oceans of dead animals and keeping others in check.
On the other hand, sharks face many threats, including overfishing, habitat loss, and pollution.
How intelligent are sharks?
Sharks are smart animals that can learn and figure out how to solve problems. They learn by making mistakes and trying again.
But they are less intelligent than mammals – like humans and dolphins. Their brains are different, and they don’t have the high cognitive abilities they do.
Why do hammerhead sharks have a head like that?
Hammerhead sharks have strangely shaped head that helps them find prey more easily.
The eyes are positioned on the sides of the shark’s distinctive hammerhead, allowing 360° of vision in the vertical plane, so they can always see above and below them.
How do sharks reproduce?
Some, like the whale shark, have live babies, while others, like the tiger shark, lay eggs. Some are also known for their ability to have offspring without a mate.
