With standardized IQ tests, IQ tests are designed so that their scores have a âbell curveâ distribution in the general population with an average of 100. This curve has a peak in the middle where most people score and tapering ends where only a few people score. In statistics this is called a normal distribution.
The Blue Whale, Largest Animal On Earth. The blue whale, Balaenoptera musculus, is the largest animal ever to have lived on Earth. Depending on which expert is cited, blue whales once attained lengths of 100 to 120 feet (32 meters) and have weighed up to 160 tons (145 metric tonnes). Blue whales are found throughout the worlds oceans.
Six species of baleen whales are found in Antarctica, including the huge blue whale which is the largest animal that has ever lived. It grows up to 24 metres and can weigh 84 tonnes. Other baleen species are the fin, southern right whale, sei, minke and humpback. Four species of toothed whales are found in Antarctica. Except for the sperm whale, they are much smaller than the baleen whales and weren't widely hunted. The other species are the southern bottlenose whale, the orca whale and the southern fourtooth whale.
