Salt Marsh Snake
Nerodia clarkii
Salt Marsh Snakes are nonvenomous coastal watersnakes adapted to Florida's brackish marshes, mangrove edges, and tidal creeks.
Salt Marsh Snakes live where freshwater and saltwater meet. Color varies widely among subspecies and individuals, from dark stripes to reddish or nearly solid patterns.
They hide in crab burrows, shoreline vegetation, and wrack during the day, then hunt small fish as water levels shift.
Habitat:
Mangroves and Salt Marshes, Estuaries and Bays
Area / Range:
Atlantic Coast, Gulf Coast, Florida Keys
Diet:
They feed mainly on small fish, especially killifish and other species trapped in shallow tidal water.
Behavior:
These snakes forage along mud, mangrove roots, and tidal pools. They are secretive and usually escape into water or cover when approached.
Dawn and Dusk, Night
Active Times:
Best time to see:
After sunset or around low tide along quiet salt-marsh and mangrove shorelines.
Florida Native Status:
Native
Conservation Status:
Locally secure where tidal habitat remains intact. Coastal development, road mortality, and mangrove or marsh loss reduce habitat.
Safety Level:
Low Risk
Safety Information:
Nonvenomous, but any wild snake may bite if restrained. Observe without handling and give it a clear route back to cover or water.
Benefits to Property:
They help regulate small-fish populations and indicate a functioning tidal shoreline.
Property Concerns:
They do not damage structures or landscaping. Shoreline hardening and pesticide runoff create greater risk to the snake than the snake creates for people.
Fun Fact:
Specialized glands help this species cope with salt absorbed from its coastal environment.
Wildlife Laws:
Native snakes should not be killed or harassed. Collection and possession are subject to current FWC rules, and protected lands may prohibit all wildlife collection.
Identification:
Look for a small to medium watersnake with keeled scales, a narrow head, and variable stripes or bands. Gulf Coast animals often show lengthwise striping, while mangrove-region snakes can be reddish or dark.
