The Iguana Specie

In Costa Rica the most common species of iguanas is the Ctensaura which is found only in Guanacaste and the Iguana Iguana also known as the green iguana found only in the Caribbean Coast of Costa Rica.

The iguana family has 8 different types : the Galapagos marine iguana, the Fiji banded iguana, the land iguana, ground or rock iguanas, the desert iguana, the common green iguana, the rock dwelling iguana and the spiny-tailed iguana. Many smaller iguanine lizards also exist.

Within the green iguana family there are different characteristics, some iguanas have one or more small horns on their nose whilst others do not. Previously these were known by two different names, the Iguana Iguana rhinolopha and the simple Iguana Iguana .These two types crossbreed and yield offspring, some of which bear horns and some of which do not.
Nowadays most people refer to only the Iguana Iguana group.

In the Gandoca-Manzanillo refuge the Iguana Iguana rhinolopha is the native species. The green iguana hatches at 7in (17.8cm) and grows to 6ft (1.8m). The tail accounts for two-thirds of the total length and is used as a weapon against predators.

Iguanas are mostly found in low lands, coastal areas, around rivers and around the boundaries of woods. There territory is up to 1000 meters above sea level. In areas higher than this it is to cold for the green iguana to survive. They need tropical temperatures approximately between 29 and 31 degrees Celsius in order to survive.
