With no thanks to deforestation and other construction, the Rhinoceros Iguana is an endangered lizard species and concerns continue to grow with regards to how many of these wonderful iguanas are left in the wild. Keeping these lizards in captivity isn’t easy but it is possible with the right enclosure and environment surrounding it – these reptiles like to be kept in enclosures outside in warm temperatures so if you live in a cold environment it’s not wise to house these lizards.

These reptiles do not have a huge population thus considered endangered and only have a population in the wild of less than 16,000 – which isn’t a lot across the whole planet and considering this is only an approximation there could be a lot less. Luckily there are a lot of professional institutions such as zoos and other associations that are rapidly reproducing these reptiles in captivity.

Rhinoceros Iguanas habitat the island of Hispaniola, Haiti and also populate the Dominican Republic – they are often found within the woodlands, dry forests, and the coastal terraces so if you do not already live in a hot country it would be hard to mimic their highly preferred environments.
