A shark is a marine fish. Most sharks are carnivores but the biggest sharks are usually herbivores.
These incredible creatures have been around for a very long time, way before the dinosaurs!
They are EXTREMELLY important to the ocean, without them would be a disaster for the ecosystems in marine life!
This is a whale shark, the biggest fish on the planet! It can grow up too 40 feet! (12 metres)

3. What type of sharks are there?
There are 440 species of sharks, and it is predicted that there are more to discover!
Sharks are split up into 8 different groups: this PowerPoint will give a brief description of what type of sharks are in these groups!

4. Hexanchiformes
Hexanchiformes are a group of sharks that are also known as Cow sharks. They have 6 or 7 gills, have only one dorsal fin, and large tear drop shaped eyes! They live deep down in the ocean.
Sharks found in this sub group include blunt nosed six gill shark.

5. Squaliformes
Squaliformes have 5 gills and 2 dorsal fins. They range from being 21.2 cm (the Dwarf Lattern Shark) to as big as 7.4 m in length! (Greenland Shark) These sharks tend to stick to deep depth, a Portuguese Shark has been noticed 3675m deep!

6. Squatiniformes
Squatiniformes have flattened bodies, five gills, 2 spineless dorsal fins, no anal fin and there mouth is at the front. These type of sharks prefer warmer, temperate or tropical climates. An angel shark is a good example for this type of shark.

7. Pristiophoroformes
These sharks also have no anal fin, 5 or 6 pairs of gill slits and have a long saw like snout. These sharks are also known as saw sharks and there are 8 species of them. They prefer warmer climates, such as south Africa and Cuba.

14. Hexanchiformes
These sharks have an anal fin, 6-7 gill slits and 1 dorsal fin. Sharks in this family include frilled and cow sharks.

15. Prehistoric Sharks!
This rare frilled shark was once again discovered when experts thought it may be extinct. These sharks are now very rare.

16. Lets also not forget one of the largest sharks ever to exist, the Megalodon! Remember only 11% of species in the ocean have been discovered, the Megalodon could still be alive…

17. Why are humans so afraid?
What’s the problem?
Why are humans so afraid?
When it comes to fears, sharks are high on the list… but why? At maximum sharks kill 5 people a year, mainly due to them taking a bite and leaving the victim. You are more likely to be killed by a coconut, lightning or even your own toaster!

18. Have you heard of ?
This famous film was released to the public in 1975 and was created by
Steven Spielberg. This film was a total phenomenon as it was the first
film about shark attacks. The great white shark became hugely infamous.
This film caused the global fear of sharks, and because of this it caused
a huge fishing frenzy. People went out to sea and killed millions of great whites
purely because they feared them.

19. 73 sharks are killed PER HOUR
PEOPLE ARE WRONG!
People hunt sharks for their fins especially as ‘shark fin soup’ is a delicacy in places. They cut of the fins and dump the rest of the body back in the ocean, sometimes alive.
73 sharks
are
killed
PER HOUR
Approximately 100 million sharks
are killed a year. Unfortunately the
Number of sharks may go up to 273 million
being killed a year.

20. HUMANS ARE THE 2ND HIGHEST REASON FOR HUMANS BEING
KILLED. HUMANS KILL
APPROXIMATLEY 475,000
HUMANS A YEAR.

21. Besides, why be afraid of sharks
Besides, why be afraid of sharks? MOSQUITOS KILL THE MOST HUMANS EVERY YEAR! They kill 1 million people every year!

22. Don’t kill sharks; save them!
Sharks are vital for the ecosystem, keeping the food chains in balance. Without them, the ocean is in serious danger. Luckily there are people out there who are trying to prevent this.
