DeKay's Brownsnake

Fascinating facts about the DeKay's Brownsnake

• Less than a foot long, adult De Kay's brown snakes rarely exceed 12 inches (30 cm) but the longest recorded individual measured 19 ⅜ inches (49 cm). Juveniles hatch at about 3 inches (7.68 cm) and double in size by their second summer, reaching sexual maturity at two to three years. This tiny stature lets them slip into garden cracks and under city stones, where they hunt slugs and snails that larger predators miss, helping gardeners keep pest mollusks in check.
• De Kay's brown snakes thrive where humans live, preferring moist urban habitats and often hiding under rocks, logs. They are solitary, yet aggregations have been observed, and they sometimes share winter dens with garter, red-bellied, and smooth green snakes. Their ability to live from sea level up to 1,400 m (4,600 ft) across wetlands, grasslands, dunes, and forests explains why they are a common North American snake.
• Females store sperm seasonally, allowing them to delay fertilisation until prey are abundant, then give birth to live young in late summer. Litters range from 3 to 41 offspring, with most reports noting 12-20 young born between late July and early August. Because the young are precocial and receive no parental care.
• When threatened, De Kay's brown snakes coil their front body and sway side-to-side, then release a foul musk from the cloaca. This dual defence, visual motion and chemical spray, helps deter predators such as larger snakes, frogs, toads, birds, and even invasive housecats. Their shy nature keeps them hidden under rocks or logs, making them hard to spot but effective at surviving in both wild and urban settings.
• Specialised jaws let De Kay's brown snakes extract snails from their shells. In the north they eat mostly slugs, while in the south earthworms dominate their diet. By controlling mollusk populations, they reduce crop damage.
