leguan

Leguan is the common name used in German for iguanas, a group of large lizards native to the Americas and the Caribbean. The best-known species is der Grünleguan (Iguana iguana), which ranges from Mexico through Central America into parts of South America. Adults can reach up to about 1.5 meters in length, including the tail. They have a dewlap under the chin, a row of spines along the back, and long claws for climbing.

Leguane are primarily terrestrial and arboreal, often found near rivers or in tropical forests. They prefer warm, humid environments and are strong swimmers, using their tails to propel themselves between trees or across water.

Diet varies with age: adults are mainly herbivorous, feeding on leaves, flowers, and fruit; juveniles may consume insects. They are diurnal and can be quite territorial, with males displaying the dewlap and head bobbing during courtship.

Reproduction and development: females lay eggs in a nest dug in soil, typically laying dozens of eggs. Incubation lasts about 60 to 90 days depending on temperature. Hatchlings are independent soon after emerging.

Conservation and human use: some species face habitat loss, hunting, or collection for the pet trade; the green iguana is widespread and not currently threatened, but others with restricted ranges are. In some regions, released or escaped iguanas can become invasive, affecting local ecosystems.
