Intrigued, they carried out similar tests on few other species, such as dolphins and whales, and found the same results.</p> <p>According to fossil evidence, whales are believed to have descended from a four-legged primitive ungulate (hoofed mammal) which lived on land and was similar to the modern day hippopotamus. Like the hippopotamus the whales come to the surface for breathing to this day. However, tests carried out on hippopotamuses and river otters (close relatives of seals) showed that both species are receptive to the blue color.</p>
