They are easy to spot due to their– as the name tells – green colour. Tail included, they can grow longer than 2 metres and weigh up to 10 kg. Green iguanas spend most of their lazy lives on trees, but are also good swimmers. The spines along their back and tails evoke memories of a long-gone dinosaur era (male spikes are longer and thicker than the female’s).
Despite their very sharp teeth, they are herbivores, but young green iguanas usually also feed on insects. Thanks to sharp claws on their hind legs, iguanas are excellent climbers.
Breeding occurs during dry season, when the female lays clutches of ca. 40 eggs. After 11-15 weeks of incubation the hatchlings emerge. As they lack dorsal spines, they are more resembling to female iguanas than males.
