The reptiles and amphibians of Connecticut encompass 48 species.
Reptiles have scales and claws on their feet. They cannot regulate their body temperature internally, it varies with their environment. Their eggs have shells that protect them and make them less dependent on mositure. Some reptiles bear live young.
Amphibians have skin that is not scaled and is permeable. Their feet are covered with skin and do not have claws. They have gills in the early stages of their lives. Most will develop lungs in adulthood, but some become skin-breathers and a few retain gills into adulthood. Like reptiles, their body temperature is dependent on the environment. Amphibian eggs require a moist environment to survive, and are often laid in the water.
