American bullfrog
Cartwright and Jordan are the authors of "Alien Invaders", published by Book Works, which takes the form of a guidebook to non-native species found in Britain, and the effects on native wildlife. Drawing on both scientific fact and cultural anecdote, and offset by the artists' interventions, ten invasive species are categorised and illustrated, including the American bullfrog, giant hogweed, pharaoh ant and wels catfish.
