What happens when two Galapagos giant tortoises meet on a narrow pathway going in opposite directions? Thanks to this video from WWF we know the answer to this intriguing question. Like many other species, they establish which animal is dominant and go from there. In the case of the giant tortoise it seems that height (or neck length really) is a crucial factor in establishing dominance. Watch as these two behemoths face off and decide who gets to stay on the path and who has to go around.
