Murdoch University researchers have found that dolphins in Shark Bay shake conch shells to cause fish sheltering inside to fall into their mouths. This phenomenon had been observed half a dozen times over the past two decades, but seven times since May, promoting speculation the dolphins may be learning it from friends. The scientists want to know if the dolphins plan in advance by moving shells to make them better refuges for fish. Source: Reuters
