Family

Order: Squamata; Suborder: Serpentes; Family: Colubridae; Subfamily: Natricinae; Genus: Nerodia; Species: fasciata

Conservation

Least Concern (IUCN); however, they are often killed by humans who mistake them for Cottonmouths.

Physical Description

Heavy-bodied snake with strongly keeled scales. Features dark crossbands (brown, reddish, or black) on a lighter ground color. The head is wider than the neck with large eyes and round pupils. A dark stripe usually runs from the eye to the corner of the mouth.

Size & Dimensions

Small to medium; this specimen appears to be a juvenile. Adults typically range from 24 to 42 inches (61-106 cm), with a maximum record of about 60 inches (152 cm).

Habitat

Semiaquatic; found in freshwater environments including lakes, ponds, marshes, cypress swamps, and slow-moving rivers. Often seen basking on logs or vegetation overhanging water.

Diet & Feeding

Generalist carnivore focusing on aquatic prey; primarily eats fish, frogs, tadpoles, and occasionally salamanders or crayfish. They use active foraging and strike-and-swallow tactics.

Reproduction

Viviparous (gives birth to live young). Breeding occurs in spring, and females give birth to 15 to 60 neonates usually between July and October.

Conservation Status

Least Concern (IUCN); however, they are often killed by humans who mistake them for Cottonmouths.

Cultural Significance

Ecologically vital as both a predator of aquatic pests and as prey for larger wading birds and alligators. In Florida, they are a staple of the wetland ecosystem.

Notable Features

Features extremely keeled scales that give the snake a rough texture. Unlike most other snakes, they can be found in brackish water occasionally, though they prefer freshwater.

Notes

Florida. Aggressive
