Conservation
IUCN Red List status is Least Concern, though local populations can be impacted by wetland drainage and degradation.
Physical Description
Glossy black or dark bluish-black dorsal coloration with a distinctive bright red and black checkered belly that extends onto the lower flanks. The head is relatively narrow and indistinct from the neck, and the tail terminates in a sharp, horny spine.
Size & Dimensions
Estimated specimen length is around 3 to 4 feet. Adults typically range from 40 to 54 inches (102 to 137 cm), with a maximum recorded length exceeding 80 inches.
Habitat
Highly aquatic, typically found in sluggish freshwater habitats such as cypress swamps, marshes, bayous, and the edges of lakes and ponds. Often burrows in soft mud or hides beneath debris.
Diet & Feeding
Specialized diet consisting almost entirely of aquatic salamanders (such as amphiumas and sirens) and occasionally frogs and small fish, hunted primarily in shallow, muddy water.
Reproduction
Oviparous, laying clutches ranging from 4 to over 100 eggs in late spring or summer, often deposited in damp soil or decaying vegetation near water.
Look-alikes
Commonly confused with other dark-colored aquatic snakes such as cottonmouths or swamp snakes, but easily distinguished by its glossy black back, lack of vertical pupil, and striking red-and-black belly pattern.
Conservation Status
IUCN Red List status is Least Concern, though local populations can be impacted by wetland drainage and degradation.
Cultural Significance
Often subject to folklore, including the unfounded myth of the 'hoop snake' that allegedly takes its tail in its mouth and rolls like a hoop to chase people.
Notable Features
Features a sharp tail spine used by the snake to probe or prod prey during handling, earning it the historical nickname 'stinging snake' despite being completely harmless to humans.
