Other common names
Most adult Red-bellied Snakes are about 8-10 inches (20-26 cm) in total length. These snakes are small and thin, and their background color is gray to reddish brown with 1-5 stripes down the back. The head is black or dark brown, and there is a light collar around the neck. The belly is normally bright red. Juveniles are darker than adults and have a whitish band across back of the head.

Adult Red-bellied Snakes in Florida are about 8-10 inches (20-26 cm) in total length, with a record length recorded of 16.6 inches (42.2 cm). These snakes are small and thin, and their background color is gray to reddish brown. Faint striping down the back varies from one broad stripe, to four narrow stripes, to a combination of both patterns resulting in five stripes. Three light spots on the back of neck fuse together to form a light collar. The head is black or dark brown, and there is a small white spot under the eye on the upper lip scales. The belly is normally bright red, but it may also be orange, yellow, or bluish gray. The scales on the back are keeled (each scale has a prominent raised ridge) and arranged in 15 scale rows at midbody. The pupil is round. Juveniles are darker than adults and have a whitish band across back of the head.
Red-bellied Snakes are commonly found in most terrestrial and wetland habitats throughout their range. However, these secretive snakes often remain hidden beneath leaflitter, logs, rocks, or other surface cover. Adults and juveniles of this species are often found in suburban neighborhoods where development encroaches into favorable habitats.
These inoffensive snakes do not bite in defense. If captured or molested, Red-bellied Snakes will often squirm vigorously, flatten their heads and bodies, and release foul-smelling musk from two glands in the base of the tail. If further agitated, they will occasionally curl their upper lip scales upwards to expose the upper teeth.
Red-bellied Snakes are typically active at night, and they feed primarily on slugs and earthworms. However, they will occasionally eat snails and insect larvae. The feeding behavior for this species has not been described, but prey are presumably swallowed alive.
In Florida, females give live birth to around 2-6 young in early summer. The newborns are tiny and only measure about 2.5-4 in (6.5-10 cm) in total length.
No subspecies of Red-bellied Snake are currently recognized.
Red-bellied Snakes can be locally abundant in parts of their range, including in residential areas. However, these small and secretive snakes are rarely seen unless they are disturbed from their hiding places during yardwork or heavy rains. Otherwise, they are typically found by actively searching for them under rocks, logs, or other surface cover.
