Anaxyrus is a genus of toads commonly found in North America. These toads are characterized by their warty skin, stout bodies, and short limbs. They typically inhabit a variety of environments, including deserts, grasslands, and forests, and are known for their distinctive calls during mating season. Members of the Anaxyrus genus are primarily nocturnal and feed on insects and other small invertebrates. They play an important role in their ecosystems by helping to control insect populations. Some species within this genus, such as the Anaxyrus boreas, are also of conservation concern due to habitat loss and environmental changes.
