Domestic pigs, when released into a feral environment, undergo significant physiological and behavioral changes. One such adaptation involves the development of prominent tusks, particularly in males. These tusks, formed from the canine teeth, continuously grow and are sharpened by grinding against the lower set. This differs from their domesticated counterparts, whose tusk growth is often stunted by selective breeding and management practices.
The re-emergence of tusks in feral pigs plays a vital role in their survival. They are essential for foraging, rooting for food, and defending against predators or competing for resources. This physical characteristic underscores the adaptability of the species and the impact of environmental pressures on phenotype. Understanding this adaptation is crucial for managing feral pig populations and mitigating their impact on ecosystems.
