Hatchlings are typically cm in upon emergence from their eggs. Habitat: The cat-eyed snake is found only in the extreme southern portions of the state in thornscrub and subtropical habitats.

Campbell recognized Leptodeira populations from southern Mexico to Costa Rica as a separate species, L. Habitat 6 Leptodeira annulata can be found in a multitude of environments ranging from semi-arid scrub to rain forests. In Mexico, these snakes have been documented at elevations of up to 1, m. Range elevation: 1, high m. Habitat Regions: temperate ; tropical ; terrestrial Terrestrial Biomes: desert or dune ; rainforest ; scrub forest Aquatic Biomes: lakes and ponds; rivers and streams; temporary pools Morphology 7 Leptodeira annulata is characterized by a head that is much wider than its neck and large eyes with vertical pupils that give the common name, cat-eyed snakes.
