Characteristics of Living Things Kyle Winberg, Haylee Ecklein, Brynna Parmelee, Destiny VanWoert
Grow and develop • The biggest shark is a whale shark and it can grow up to 46 feet long. The smallest shark is a Spined Pygmy shark and it can be only 7-8 inches long. Most sharks are about 5-7 feet long. Different types of sharks grow at different rates. Some people say that the great white shark lives up to 100 years old, but no one can prove it. The whale shark can live up to 100-150 years. Other sharks live 15-40 years of age. Sharks have no bones, only cartilage. Females are larger than males.

Reproduce Most large ones by live birth of a small number of young. The number of shark pups born to a single mother varies considerably between species. Some have only two large pups, while others, like the blue shark, may have 40 to 80 much smaller young. Researchers have figured out that female sharks can reproduce on their own. Depending on the species, sharks can produce between 1-135 young at one time. Once born, baby sharks are left to fend for themselves.
Inheriting Traits From Parents It is like when a whale and a shark mate, they create a whale shark. So in some ways, sharks do inherit traits from their parents. Aggression from old relatives, the aquatic dinosaurs. large size from its huge relative that was 100-150 ft long. sense of smell from dinosaurs and eye-sight from the murky waters its cousin used to live in.

Made of cells • To be alive the shark has to be made of cells. In side the cells there is the nucleus, the chromosomes are part of the nucleus. When one of the sharks cell dies a new one will take the places of the dead one.
Obtain and use energy and nutrients. • Sharks eat sea mammals, (seals, dolphins, and porpoises, etc.) The shark also eats other mammals that are the most easy to catch because the sharks mostly go after the slow ones because the shark is over 400 pounds.
How sharks respond to the environment. • Most sharks don’t adopt, simply because they don’t need to. Many stay in one place.

Maintain a stable environment in their cell and bodies • Sharks are cold blooded and to warm them they move to warm waters. When the weather change they move to cold waters.
