About This Creature
A slender snake with distinctive brightly colored banding consisting of wide black and red rings separated by narrow yellow rings. Typically reaches a total length of 20 to 30 inches, with a blunt, black snout and small head not distinct from the neck.
Physical Characteristics
Smooth scales, cylindrical body, round pupils, and a short tail. Possesses a potent neurotoxic venom delivered via fixed, short front fangs, with the famous mnemonic 'red touch yellow, kill a fellow' used to distinguish it from harmless mimics.
Behavior & Temperament
Secretive, shy, and non-aggressive, usually only biting when stepped on, handled, or intentionally provoked. Primarily nocturnal or crepuscular, spending daylight hours hidden underground or beneath debris.
Habitat & Diet
Origin Region
Southeastern United States, ranging from North Carolina to Florida and west to Louisiana
Habitat
Pine flatwoods, scrub, hammocks, and sandhills; primarily terrestrial and somewhat fossorial, often hiding under leaf litter, logs, or in burrows
Diet & Nutrition
Carnivorous, feeding primarily on other snakes (such as small earth snakes and crowned snakes), lizards, and occasionally amphibians.
Lifespan & Health
Lifespan is around 7 years in the wild, potentially longer in captivity. Predators include birds of prey, larger snakes, and mammals. Reproduces via oviposition, laying small clutches of eggs during the summer.
Special Characteristics
Highly venomous elapid possessing a powerful neurotoxin that affects the nervous system and can cause respiratory paralysis in humans, though bites are extremely rare due to its secretive nature.
Ecological Information
Acts as both a predator of small reptiles and prey for larger carnivores, helping to maintain the balance of small vertebrate populations within its native forest and scrubland ecosystems.
