Northern Alligator Lizard

Northern alligator lizards live up to their given name; they are sleek, slender reptiles with long tails; they can grow up to 10 inches in length. Their long tails usually make up almost twice their body length, which can give them the appearance of small alligators. They have triangular-shaped heads and pointed snouts, and their eyes are usually dark brown to black. You may have to look hard to find one; their brown or brownish-green upper bodies blend into their surroundings quite well.     

Habitat

Northern alligator lizards are found northern Idaho, and they prefer cooler and wetter environments more than any other species of Idaho lizards. They are often found in forest clearings or edges, under logs and other surface debris. They can also be found in rock rubble slopes that are associated with forests.

Fun Facts

Northern alligator lizards are one of only two species of Idaho lizards that give birth to live young (viviparous) rather than laying eggs (oviparous). The young lizards (neonates) look just like their parents, except they have a brownish stripe on their backs and are a lighter color until they become adults
