Cervus is a genus of deer that includes several species, such as the red deer and sika deer. These animals are known for their antlers, which are typically found on males and are shed and regrown annually. Cervus species are primarily found in the Northern Hemisphere, inhabiting forests, grasslands, and mountainous regions. Members of the Cervus genus are herbivorous, feeding on a variety of vegetation, including leaves, grasses, and fruits. They play a significant role in their ecosystems by helping to maintain plant diversity and serving as prey for larger predators, such as wolves and bears.
