Description
''S. occipitomaculata'' is a small woodland species that ranges from 4–10 in (10-25 cm) long. Their colors range from an orange to gray, black, or brown. They can be distinguished from other species from their bright red or orange underbelly.
Habitat
''S. occipitomaculata'' prefers warmer habitats and in the more Northern limits of its range will inhabit abandoned ant mounds. These mounds absorb solar radiation and are insulated which allows for a longer active season. This species, with large eyes and a kinetic skull, are not able to burrow on their own effectively and abandoned ant mounds allow them access to a warm area to retreat to.
Reproduction
Redbelly snakes have been studied to reproduce annually and females have been found to be gravid during the spring and early summer. While body size varies throughout the redbelly snake's region, the average clutch size tends to remain the same with an average of 7-9 eggs per clutch.
Subspecies
Three subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species ...
