There are over 2100 species of snakes found worldwide. Of these, only about 10% are venomous with even fewer posing a threat to humans. Snakes have evolved to be very effective predators and can be found in nearly every habitat and niche on Earth. Most non-venomous snakes use their tongue-flicking sense of smell and taste to locate prey. After killing its prey, often by constriction, a snake can unhinge its jaw to swallow their meal whole.nnSpecifications:nnThe photos shown are examples of what your specimen will approximately look like.
