Land snail (Wainuia urnula) eating an earthworm

New Zealand has around 1,000 species of native land snails. Some are as big as the palm of a hand, although most, like this species, are much smaller. Land snail shells range in colour from red-brown to yellow and black, with whorls extending from the centre. Most species favour the forest floor, and some such as Wainuia urnula seen here, like to eat earthworms.
