Rubber boas are unique and often misunderstood snakes native to western North America. This article clarifies their characteristics and behaviors, addressing common concerns regarding their safety.
Understanding Rubber Boas
Rubber boas (Charina bottae) are among the smallest members of the boa family, typically ranging from 14 to 33 inches in length and weighing less than three ounces as adults. They possess a distinctive appearance with smooth, glossy scales that give them a rubbery texture, usually in shades of tan, brown, or olive, with a lighter underside. A notable feature is their uniformly thick body and a blunt tail that closely resembles their head, leading to the nickname “two-headed snake.”
These snakes are often found in cool, moist environments, including forests, grasslands, and mountainous areas, from sea level up to 10,000 feet. They are reclusive and primarily nocturnal or crepuscular, meaning they are most active during dawn and dusk. Rubber boas spend a significant portion of their time hidden under rocks, logs, leaf litter, or in rodent burrows, contributing to their infrequent sightings. Their movements are generally slow, and they exhibit a docile and gentle temperament.
Assessing the Danger
Rubber boas are not dangerous to humans. They are non-venomous snakes and lack fangs. Their primary defense mechanisms are passive, involving coiling into a tight ball, concealing their head within their coils, and elevating their blunt tail to mimic a head, potentially confusing predators. If severely provoked, a rubber boa might bite, but such instances are exceptionally rare due to their shy nature.
A bite from a rubber boa is generally harmless, often described as feeling like a small needle prick or a minor abrasion. Their teeth are small and not designed to inflict significant injury to humans. Any bite typically results in superficial puncture wounds that should be cleaned thoroughly with soap and water to prevent infection. They may also release a musky odor when feeling threatened, which serves as a deterrent.
Safe Encounters
Encountering a rubber boa in its natural habitat is an uncommon occurrence given their secretive lifestyle. If you do see one, observing it from a distance is recommended. These snakes are generally not inclined to approach humans. Handling a rubber boa should be avoided unless absolutely necessary, such as for relocation, as it can cause stress to the animal.
Rubber boas can sometimes be found in residential areas, including gardens, as they seek shelter and prey like rodents. If a rubber boa is found in an undesirable location, it can often be gently coaxed into a container, such as a bucket, and safely relocated to a nearby natural area. If you are uncomfortable with direct contact, contacting local animal control or wildlife authorities for assistance is a good measure. These snakes play a beneficial role in the ecosystem by preying on rodents, contributing to natural pest control.
