-- When attacking prey from below, the  great white shark's power through the water often causes the sharks to completely breach. In cases like this, the shark will cover its eyes with protective slits just before it strikes its prey to prevent any damage.
-- A great white shark can go up to 35 miles per hour. This speed allows it to charge toward its prey in ambush and also allows it to migrate in search of food, ideal water temperature and mates.
-- Most bony fish have just one gill slit on each side of their bodies. Great white sharks, however, have five to seven. This is because they take in a lot of oxygen. In fact, they ram oxygen into their bodies as they move forward, which is why they have to keep moving. If they don’t, they won’t be able to breathe and they will suffocate and die.

Sows give birth to usually 1 or 2 one-pound cubs and then nurse them until they reach about 20-30 pounds before emerging from the den

-The bald eagle is not picky about how it gets its food. It will eat carrion, steal fish from other birds or hunt for its own.

-While in their mother's womb, young great whites swallow their own teeth!
-When one great white wants to take the other's prey, both sharks will display various slapping demonstrations to discourage each other.

4)Availability of food
Great white sharks prey upon halibut, salmon, tuna, rays, other sharks, dolphins, porpoises, whales, hair seals, fur seals, elephant seals, sea lions, sea turtles, sea otters, seabirds and invertebrates.They take large prey and more marine mammals as they grow older.

-Sharks can regrow their teeth when they accidentally break one.

1)Light:the great white sharks do not need light to survive
2)Temperature:The water temperature in the sea is  between 12 and 24 °C (54 and 75 °F)
3)Water:The great white shark does not drink water as the blood and the tissue of the shark is salty and they absord pure water from the sea by osmosis.

# data[].attributes.body
1)Light:when the weather changes,the light affecting it changes too.
2)Temperature:Bald eagles are quite adaptable to extreme weathers/temperatures.
3)Water:bald eagles do not need water as they derive water from the food they consume.

~ sharks have lateral lines ( see below ) to help them sense any sea creature that is bleeding or struggling in the water.
~ sharks also have  electroreceptors thathelp find stingrays, their greatest prey.

4)Availability for food
Bald eagles eats a lot of fish and birds.The average amount of fish an eagle can eat in a day is 5-10% of eagles' body weight. Besides humans,Other bald eagles occassionaly attack eagles and their young; racoons will sometimes kill young in the nest as will the occasional great horned owl.

-The great white is found in temperate oceans, preferring a temperature ranging between 54 and 75 degrees.
-One of the densest known great white shark populations lives around Dyer Island, South Africa, which makes the area a prime shark research location.
-Great white sharks are rare in both polar and tropical waters.

5)Other kinds of living things:
During the sunlit seasons, serves as habitat for an ice-specific food web (sympagic foodweb) [1] that includes bacteria, viruses, unicellular algae,

# data[].attributes.body
-- The bald eagles' wide tail works as a rudder system and allows the bird to maneuver and switch direction quickly when hunting.
-- Bald eagles protect themselves by growing to a large size that makes it difficult for other winged predators to capture them, by being able to fly away from large land predators and by being strong enough to attack prey easily.

-- Once the prey has been clasped in the bald eagle's talons, it fly away before a land predator comes along.

# data[].attributes.body
~ the talons of the eagle (see below) help the eagle capture and kill prey
~ the upper mandible (upper jaw) of the eagle's beak is sharp and is used to tear away the skin of prey
~ the beak is also used for protection against predators
FUN FACT: The eagle's beak is made of keratin, which is the same material that human toes and fingernails are made of.

-Bald eagles like big lakes. -During the summer, they can be seen soaring above lakes and in the nearby trees.
-During winter , eagles are seen flying around water habitats like lakes, reservoirs and etc finding its prey

4)Availability of food
A polar bear's body requires a diet based on large amounts of seal fat.
A 121-pound seal can provide 8 days worth of energy.

# data[].attributes.body
-Polar bears are marine mammals, and spend much of their time on Arctic sea ice.
-Many adaptations make polar bears uniquely suited to life in icy habitats.

# data[].attributes.body
-- Polar bears exhibit some aggression to protect their cubs or food and to compete for females.
-- Pregnant polar bears hibernate through the winter in their dens and their cubs are born in the dens, protected from the harsh weathers outside, and hence are healthier and have better chances of survival.
-- They use the body of fat during hibernation and can also use it during conditions of food scarcity

# data[].attributes.body
1)Light: in mid-winter, the sun does not rise, and a couple of weeks in summer, there is 24-hour sunlight.
2)Temperature:10°C on the Antarctic coast to −60°C at the highest parts of the inferior
3)Water:water is not easily available when the water/ground freezes

# data[].attributes.body
~ Polar Bears have small ears to reduce heat loss
~ Large feet to spread it's load on snow and ice (basically so that it will not slip)
~ they also have fur on the soles of their feet to reduce the chances of slipping (increases friction between paws and ice)
~ they have a thick layer of fat to keep itself warm and store energy
