New bottlenose dolphin sense discovered: Research suggests they can feel weak electric fields
Born tail first‚ bottlenose dolphin calves emerge equipped with two slender rows of whiskers along their beak-like snouts—much like the touch-sensitive whiskers of seals. But the whiskers fall out soon after birth‚ leaving the youngster with a series of dimples known as vibrissal pits. Recently‚ Tim Hüttner and Guido Dehnhardt‚ from the University of Rostock‚ Germany‚ began to suspect that the dimples may be more than just a relic.
