Critter of the Week: Lettuce Liverwort

This week's critter is the Lettuce Liverwort. You aren't likely to see a Lettuce Liverwort in your backyard these days as they grow in only one location in the Puhi Puhi valley south of Kaikoura. They look exactly like a frilly green lettuce and they're smaller than your thumbnail, which is big by liverwort standards!
