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.
Whales range in size from the blue whale, the largest animal known to have ever lived on Earth to various pygmy species, such as the pygmy sperm whale that reaches a length of around 10 feet. Whales may all be part of the same order, but shapes and sizes vary tremendously depending on species. Click on image to enlarge.
