The  World  Of  Dolphins

Welcome to my undersea world of Dolphins. Do you know that Dolphins are one of the most smartest animals in the world?Scientists also did a test to prove that.First they marked a place on the dolphins body where it can't see.Than they put a mirror down into it's tank.After that the Dolphin swam over to the mirror and positioned itself infront of the mirror so it could see where they put the mark.
