Population: Unknown, believe to be decreasing
Size: Up to 4.75 inches snout-to-vent length, 3 ounces
Threats: habitat destruction and intentional fear-based killing.
- The Five-keeled Spiny-tailed Iguana is found in three core areas that are isolated and distant from each other, along the Pacific versant of Nicaragua and northwestern Costa Rica.
- The iguanas occurs in tropical and subtropical dry forest, both in Costa Rica and Nicaragua and is sometimes found in human altered habitats.
- They are threatened by habitat fragmentation and destruction for agricultural land conversion, hunting for meat and in some areas killed because of a belief that they are poisonous.
- Currently they are protected through a seasonal ban on hunting, by the Ministry of the Environment of Nicaragua, however enforcement is lacking.
- Very little is known about the Costa Rican sub population of this species and attention should be given to this area.
