Newts, unlike other members of the family Salamandridae, are semi-aquatic, metamorphosing between aquatic and terrestrial habitats. Notophthalmus viridescens, the vibrant red-spotted (Eastern) newt, spends most of its life cycle in fresh water, except for the striking juvenile stage which is spent on land. This red-eft stage is notable for its intense colouring and clear spots along its back. The flashy red colour is a clue to potential predators- warning of their ability to secrete toxins.
