You will never see snakes in Ireland! About 12 thousand years ago, Ireland was covered by a glacier, on which snakes could not live. When it melted, Ireland was already separated from other lands by a sea that the snakes could not overcome. There are no snakes in Iceland for two reasons. First, snakes do not like cold climates, so they cannot exist here. Secondly, in Iceland, it is forbidden by law to import snakes, lizards, and turtles here. Unlike neighboring Australia, where there are a lot of snakes, in New Zealand, you will not find even one of them anywhere. Scientists assume that the absence of these reptiles here is connected with a sharp cooling that happened back in the Ice Age. Later, the island's isolation became why snakes did not appear here again. As it was before the cold weather.
