There are over 2,100 species of snake 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 the meal whole.nnSpecifications:nnThis Bag-O contains an assortment of snake ribs and vertebraenApproximately 12 grams eachnSpecimens will exhibit damagenLimited quantity item; each bag will vary
