Ctenosaura is a genus of lizards commonly known as spiny-tailed iguanas. They are primarily found in Central America and parts of Mexico, inhabiting a variety of environments, including forests and rocky areas. These lizards are characterized by their distinctive spiny tails, which provide them with protection against predators. Ctenosaura species are generally herbivorous, feeding on leaves, fruits, and flowers. They are known for their strong climbing abilities and can often be seen basking in trees or on rocks. Some species within this genus are popular in the pet trade due to their unique appearance and relatively manageable size.
