If you thought that only monkeys & humans could invent new ways to get their way in life, think again. Biologists in Canada found out that the orca is smart enough to invent & teach new methods to find food in life.
One orca threw-up some fish into the water to atract the seagulls, waited under the surface and went for the kill as the birds were eating his left-overs.
After a few months the other orcas in his group did exactly the same.
This proofs that there are more animals with an ability to teach!
