The emerald green snail has a shell as green and shiny as a jewel. That is very unusual, because most snails are brown. It lives high up in the trees of the rainforest on one single island.

Fun fact: this one is not an insect at all, it has no legs! But kids find it on every bug hunt, so it lives in Bug Wiki too.
