Axolotl (Ambystoma mexicanum), artwork. This aquatic freshwater amphibian is a neotonic (larva-like) salamander. The larval form fails to undergo metamorphosis, so the adult form has the external gills (purple) of the larva and remains underwater rather than emerging onto land. The axolotl also has a caudal fin running from its head to its tail. It is a predator, feeding on worms, insects, and small fish. Axolotls are found in and around Mexico City, Mexico. Because of their characteristics, they are used extensively in biological research.

Great crested newt
Great crested newt (Triturus cristata) underwater. It is named for the large crest that develops on the backs of the males in the mating season. The juveniles lack the dark-spotted orange bellies of the adults. This newt can reach 11-18 centimetres in length, feeding at night on invertebrates in and around water. It hibernates in the winter. The great crested newt is found in northern Europe, and is protected under European law.
