e/Gray's Paradox

Information
has gloss	eng: Grays Paradox is a paradox posed in 1936 by biologist Sir James Gray. The paradox was to figure out how Dolphins can obtain such high speeds and accelerations with what appears to be a small muscle mass. Gray made an estimate on the power a dolphin could exert based on its physiology, and concluded the power was insufficient to overcome the drag forces in water. He hypothesized that Dolphins skin must have special anti-drag properties.
