The Great White Shark
The Great White Shark, or mre professionay known as Carchorodon carcharias, is notoriously known for it great size and strength, a well as their killer instinct. The GWS is so ferocious that it is known as a apex predator, with the Orca being its only predator. With a weight of 7,328 pounds and an averge length of 15 feet, these creatures have become natural weapons of the sea.
Structure and Movement
In a basic sense, sharks have a skeleton that is made out of cartilage and connective tissue, which makes them very different from bony fish and land animals' skeletons. Although it is not the largest shark in the world, it come third behind the whale shark and the baskin shark. Despite the GWS bein mainly of cartilage, it does however contain abput 230 bones, none of which form a rib cage, and so the shark would crush itself if it were on land.
Jaw and Teeth
The jaw's surface arches and is not attatched to the ranium because it needs extra suport due to its heavy exposure to physical stress and need for strength. The teeth of a shark are embedded in the gums themselves rather than directly attached to the jaw like us. Like humans, their teeth are constantly replaced through their beginnings of their life. However, our teeth remain when we become adults, while sharks' teeth constantly replace themselves throughout its entire life!
Tails and Fins
In order for a shark to swim, it relies on the combination of both the movemen of its fins and tails. Because of the structure of their fins sharks cannot swim backwards and only forwards. Although this sounds like a disadvantage, it is important to know if they could swim backwards, they would die! The tail of the shark provides thrust, making speed and acceleration dependent on its shape.
