Native Range

Anolis evermanni is native to Puerto Rico.

Distribution in Puerto Rico

It occurs in wet forests across the island, including El Yunque rainforest, the Luquillo mountains and forest, and the Cordillera Central mountain range.

Habitat Microhabitats

In these habitats, it is most often found around trees, on rocks, or in bamboo groves.

Perching and Foraging Height

It primarily uses the upper portions of trees, 2 m (6.6 ft) above the ground, as perching sites and foraging locations.

Locomotor Adaptations

Its short legs and large toe pads let it move more easily in the upper tree canopy, especially on small branches.

Female Anolis evermanni show seasonal changes in egg production.

Peak Reproductive Period

Most individuals are reproductive from April to September, and many females carry two oviducal eggs during this period.

Non-Reproductive Period

Almost no reproduction takes place between November and January.

Egg-Laying Behavior

Like other anoles, female Anolis evermanni lay eggs and hide them after laying.
