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.

At 98 feet in length and 180 metric tons, the blue whale tops even dinosaurs to be the largest animal ever. They filter krill through their baleen, and need 4-8 tons of the tiny plankton per day to survive. Each whaleâs jaws contains about 320 pairs of black baleen plates with dark gray bristles. A blue whale tongue alone can weigh as much as an elephant. The animals live to be 80-90 years old and live all around the worldâs oceans, spending summers in cold polar waters and winters closer to the Equator.
