Snakes often evoke a mix of fascination and apprehension. Many wonder if a snake is venomous or poisonous. Understanding the characteristics of specific snake species, such as the rough green snake, can help alleviate concerns and promote safe interactions with wildlife.
Understanding Rough Green Snakes
Rough green snakes (scientific name: Opheodrys aestivus) are not venomous, nor are they poisonous. These docile snakes pose no threat to humans, rarely biting even when handled. They are one of the few entirely insectivorous snake species, primarily eating insects, spiders, and small frogs. They rely on camouflage for defense rather than aggression.
Identifying Rough Green Snakes
Rough green snakes are easily recognizable by their vibrant coloration and slender build. They possess a long, thin, bright green body with a white, cream, or yellow belly. The green coloration serves as effective camouflage among the foliage where they primarily reside. Their scales have distinct ridges, known as keels, which give them a “rough” texture and differentiate them from the smoother-scaled smooth green snake.
Adult rough green snakes typically measure between 22 and 32 inches in length, though some can reach up to 3.5 feet. They have relatively large eyes and a small head. These arboreal snakes are commonly found in the southeastern United States, ranging from Florida north to southern New Jersey and west to central Texas, preferring moist woodlands, meadows, and areas with dense vegetation, often near water.
Encountering Snakes Safely
When encountering any snake, including the harmless rough green snake, it is important to observe from a distance and avoid provoking it. Do not attempt to handle, capture, or kill the snake, as most bites occur when people try to interact with them. Allowing the snake to move away naturally is the safest approach.
In the unlikely event of a snake bite from an unknown species, seek immediate medical attention by calling emergency services. While waiting for help, remain calm, and keep the bitten area still and lower than the heart. Remove any jewelry or tight clothing near the bite before swelling begins. Clean the wound with soap and water and cover it loosely with a clean, dry bandage. Avoid applying a tourniquet, cutting the bite, attempting to suck out venom, or applying ice.
