Turtle or Tortoise?


How can you tell between a turtle and a tortoise? You can’t separate the two exactly, because a tortoise will always be a turtle too. The turtle group includes tortoises. There are, however, certain characteristics that make tortoises special turtles, so not all turtles can be tortoises. The most important factor that distinguishes the tortoises is that they are not as enthusiastic about water as other turtles. Most turtles live mostly in the water but tortoises only go for a bath every once in a while or go to water to fill up their tanks. They live on the dry land and eat mostly plants. They dig holes for home and don’t like to migrate.





There is another small group somewhat between the two that is called the terrapin. Terrapins may live in fresh or partially salty water like saltwater or mangrove marshes and may spend significant time on the land too. Of course, each animal is suited to its environment. The tortoises generally have bigger shells to store a bigger water tank and sturdy walking and digging legs while some sea turtles may have slim, water-dynamic shells and paddles for front legs. The largest turtle of all is the leatherback sea turtle and the largest tortoise is the galapagos tortoise.

The Giant Panda

                                          The Giant Panda



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.



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.
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.
