The New Zealand flatworm (Arthurdendyus triangulates) is an alien species in the UK. It was introduced accidentally from New Zealand when plants were imported. It has now spread all over the country and is considered a major pest as it feeds on earthworms. This may in turn affect soil fertility and the availability of food for vertebrates such as badgers, hedgehogs and birds.

This flatworm can grow up to 17 centimetres long. They are often seen curled up underneath stones and logs or can be found in the soil hunting for worms.

As flatworms are soft bodied they have to be preserved in spirit, when museums want to put specimens in a diorama display then models have to be made. These models were made by staff at Glasgow Museum.
