.WHALES AND DOLPHINS:

Whales and Dolphins are marine animals. They live in oceans around the world. Whales and Dolphins come from the same family, CETACEA (sey-tay-sha) . They both breath from a blowhole located at the top of their head. Whales and dolpins are mammals. They are mammals because they have lungs not gills,they have hair not scales , and they also have give live birth and don't lay eggs. There are only about 80 kinds of whales and dolphins that we know of right now.

WHALES:
Whales are very large animals. They can grow up to 100 ft. or more in length. They can weigh up to 200 tons or more. Whales live in families called pods. These pods vary in numbers and consist of family members and family friends. Whales live in these families their whole life. Group living is safer when other whales or sharks attack. It also makes it easier to find food. Whales are always migrating. They travel to find food, breed and have young.
Whales do not have eyelids. They rely on thick oily tears to protect their eyes. Whales hear from little holes behind their eyes.

Whales talk to each other by making high pitched sounds like whistles, clicks, squeaks, rattles, and groans.

To help protect the whales from extinction please DO NOT throw nets, fishing lures, or other fishing gear ocean

DOLPHINS:
Dolphins live with the whales in the oceans. But dolphins come much closer to the shore. They will come as close to the shore as you or I can walk without going under water. Dolphins have teeth.
Looking at a dolphin you would not think it as a nose, but surprise...it does! They have nostrils called blowholes. Over millions of years of evoloution whales and dolphins nostrils moved to the top of their head. This allows them to breath by surfacing instead of them sticking their whole head out of the water.
The first thing a newborn dolphin must do is to go to the surface to breathe. But the baby can not swim so its mother and a another dolphin will help push the baby to the surface for its first breath of air. The baby will be able to swim in about 30 min.
Dolphins are fast swimmers. When a speeding boat passes the bottlenose dolphin, it will start to race out in front . They will take off hitting the water and keep going.
Dolphins navigate by following the hills and mountains of the ocean floor, by tracking the sun, by sensing currents, and by tasting the water along the journey.
A dolphin's sound probably originated in its nasal passages. These nasal passages are located on the top of the head. Dolphins can make sounds to see what lies ahead. This sense is called echolocations. The dolphins' sound waves hit an object and the echo bounces back. Echolocation sounds are called sprays. Sprays are so strong they can stun another whale. Dolphins don't "point" their melons at any other sealife except their enemies.

SHARKS:
Out of all the species walking, flying, slithering or swimming, there aren't many who have been around as long, survived as well, or come in so many shapes and kinds as the shark. The earliest evidences of sharks are isolated spines, teeth and scales that appeared about 430 million years ago in the Silurian Period, known as the "Age of Fishes". Sharks have a sleek, streamlined design which helps them swim without using up a lot of energy.They certainly need to conserve their energy because they never really sleep and most of them never stop swimming.

Some sharks are fierce predators, and would be happy to eat you if they encountered you. Almost any shark six feet or longer is a potential danger, but three species have been identified repeatedly in attacks: the Great White Shark, the Tiger Shark and the Bull Shark . All three live world wide, reach large sizes and eat large prey such as marine mammals or sea turtles. But most sharks never grow longer than five feet and never even see anyone with legs and arms anyway. People kill thousands more sharks every year than sharks kill people.

Sharks take about as long to mature as we do. Some of them become adults in their teens. A mother shark carries her babies inside her body while they develop, sometimes for more than a year. Even so, some sharks are born inside an egg which they have to crack open. They spend early portions of their lives in nursery grounds. Some of the advantages sharks have over people is that they keep growing new teeth, they don't have breakable bones, and they are not prone to get cancer. Sometimes sharks are referred to as swimming computers because of the six senses which they possess: vision, hearing, vibration, smell, taste and electro-perception
