Bigens

Bigens refers to a group of small, non-venomous snakes belonging to the genus Heterodon. These snakes are commonly known as hognose snakes due to their upturned snouts, which they use for digging. There are several recognized species of bigens, primarily found in North and Central America. They are characterized by their distinct defensive behaviors, which include flattening their heads and necks to appear larger, hissing loudly, and even playing dead by rolling onto their backs and emitting a foul odor. Despite their dramatic displays, bigens are generally docile and pose no threat to humans. Their diet consists mainly of amphibians, particularly toads, and small rodents. Bigens are an important part of their respective ecosystems, helping to control populations of their prey. They are oviparous, meaning they lay eggs, and their reproductive cycles are typical of many snake species. Due to habitat loss and persecution by humans who mistake them for venomous snakes, some populations of bigens are facing declines.
