Other amphibians to watch out for
Mexican axolotls (Ambystoma mexicanum)
Sold widely in the pet trade throughout New Zealand, axolotls are ferocious predators that would be a serious threat to native invertebrates and fish if they were to escape from captivity.
Newts (ie. Fire-bellied newts, Cynops orientalis)
Newts are becoming increasingly common in captivity, being popular as pets. The abdomen of fire-bellied newts is bright red and the dorsal surface of the newt is dark brown to black. Newts grow to about 10cm length.
