Wild pandas live only in remote, mountainous regions in central China. These high bamboo forests are cool and wet—just as pandas like it. They may climb as high as 13,000 feet (3,962 meters) to feed on higher slopes in the summer season.
The giant panda has an insatiable appetite for bamboo. A typical animal eats half the day—a full 12 out of every 24 hours—and relieves itself dozens of times a day. It takes 28 pounds (12.5 kilograms) of bamboo to satisfy a giant panda's daily dietary needs, and it hungrily plucks the stalks with elongated wrist bones that function rather like thumbs. Pandas will sometimes eat birds or rodents as well.
Pandas are often seen eating in a relaxed sitting posture, with their hind legs stretched out before them. They may appear sedentary, but they are skilled tree-climbers and efficient swimmers.
Giant pandas are solitary. They have a highly developed sense of smell that males use to avoid each other and to find females for mating in the spring. After a five-month pregnancy, females give birth to a cub or two, though they cannot care for both twins. The blind infants weigh only 5 ounces (142 grams) at birth and cannot crawl until they reach three months of age. They are born white, and develop their much loved coloring later.
There are only about 1,000 giant pandas left in the wild. Perhaps 100 pandas live in zoos, where they are always among the most popular attractions. Much of what we know about pandas comes from study of these zoo animals, because their wild cousins are so rare and elusive.

 There are two types of elephant, the Asian elephant and the African elephant (although sometimes the African Elephant is split into two species, the African Forest Elephant and the African Bush Elephant).Elephants are the largest land-living mammal in the world.Both female and male African elephants have tusks but only the male Asian elephants have tusks. They use their tusks for digging and finding food. The elephants trunk can be used as a snorkel in deep water.An elephant can use its tusks to dig for ground water. An adult elephant needs to drink around 210 litres of water a day.

The Blue Whale


The Blue Whale



Blue whales are considered to be the largest animals that have ever existed on Earth. They are part of the baleen whales category and the rorquals family, along with the humpback whale, the minke whale, the fin whale and the Bryde's whale. A blue whale can reach almost 30 meters in length and it can have a weight of more than 200 tons. A blue whale baby can drink up to 590 liters of milk and it can add up to 90 kg to its weight daily. This might be shocking but the heart of a blue whale has the size of a car and its arteries are so big that a child could sit on them.

A medium blue whale can weight 160 tons which is the equivalent of 30 elephants or 160 people that weight 90 kg each. But despite their huge dimensions, the eyes of a blue whale are just the size of a cup of tea, and their external ear is just as big as the tip of a pencil.

Adult blue whales eat a lot of food, and their mouths can keep 45,999 liters of water, the equivalent of 256,000 glasses.

But blue whales don't swallow all this water, they use their baleen plates to filter it and extract  krill and copepods which are their main menu. Blue whales can reach speeds of 35km per hour.

Blue whales have been victims of excessive hunting over the years and they were on the verge of extinction, although they were not very easy to kill.

Blue whales can be found in all oceans. The largest populations of blue whales can be found in the Southern hemisphere, in the North Pacific and the North Atlantic Ocean.

Sexual maturity lasts from 5 to 10 years and a female can give birth to a baby blue whale every two or three years, babies  are born in warm waters during winter days. Pregnancy lasts from 10 to 12 months. i think we should protect whales so go here for more info www.defenders.org/blue-whale-adopt
