Many people notice that some sharks seem to have black eyes and wonder whether the eyes are truly black or if this look is an illusion created by anatomy and optics. In most cas...

A blue whale with white spots is an individual blue whale (Balaenoptera musculus) that exhibits white or pale markings on its mottled, bluish-gray body. The scientific name rema...
