Dolphin mums pass on tips to kids
Researchers studying a group of dolphins off the coast of Western Australia have found that mother dolphins teach their offspring to rip sponges off the sea bed to protect their snouts from stonefish while looking for food.
It is believed that rather than an instictive behaviour which the dolphins are born knowing, this clever trick is actually passed on through the generations - something that only previously only humans and chimpanzees had been known to do.
