The Great white shark is part of the Lamnidae family of sharks. They are warm-blooded fish that feed on things such as halibut, seals, sea lions, salmon, and tuna. They are the largest macropredatory fish. They can swim 25 mph with bursts of speed up to 35 mph. They reach maturity around 15 years old and their life span is estimated at 70 years. Sharks do not have bone which makes it difficult for scientists to determine their age.
Species- Carcharodon carcharias
The latin name means “jagged-tooth one”. The sharks teeth have jagged edges. The top and bottom jaws move. They have 5 rows of teeth and can have up to 3,000 teeth. They never run out of teeth because once one falls out another one comes in.

Almost all off shore waters
Water can be as shallow as 3 feet

...during global warming where the water levels are decreasing due to heat. The Great white shark has the ability to adjust its body temperature in cold waters only. They are unable to adjust their body temperature to make it colder if the water is too warm. The shark will need to migrate to an area where the water has better temperature. The rise in sea temperature will result in a decrease in oxygen in the water.
With water levels decreasing this will cause the sharks food source to die or migrate to areas as well. This will cause the sharks to migrate they will need to migrate to areas with more food. They will need to travel further and further to find what they need especially since the sharks have a big appetite.
The sharks may need to depend even more on their senses they have. They will have to rely more on their sharp sense of smell to detect food supply
