A keelback snake, scientifically known as "Rhabdophis," is a type of non-venomous snake belonging to the family Colubridae. These serpents are primarily found in the Asian continent, inhabiting regions such as India, China, Southeast Asia, and parts of northeastern Australia. The term "keelback" refers to the prominent keeled scales on their back, which are sharply angled, giving them a ridged appearance.
Keelback snakes come in various sizes, usually ranging from about one to four feet in length, depending on the species. They possess an elongated body, a distinct head, and round eyes with vertically slit pupils. The coloration of their skin may vary amongst species, but they commonly exhibit shades of olive green, brown, or black, some adorned with yellow or orange markings.
In terms of habitat, keelback snakes occupy diverse environments, including wetlands, grasslands, forests, and even suburban areas. They are semi-aquatic creatures, often found near water sources, such as rivers, ponds, and marshes, where they display their excellent swimming abilities.
Feeding primarily on amphibians, such as frogs and toads, keelback snakes possess specialized teeth and jaw structures that aid in grabbing and subduing their prey. However, they aren't strictly amphibian eaters; their diet can also include small fish, lizards, and even other snakes.
Regarding behavior, some keelback species have the unique ability to secrete toxins, which they synthesize from the poisonous substances present in the toads they consume. This adaptation makes them distasteful and potentially dangerous to predators, serving as a defense mechanism.
