Langerhans, Knouft & Losos call the set of Anolis lizard ecomorphs of the Greater Antilles "a classic example of convergent evolution." [ 4 ] [ 5 ] Jonathan Losos defined six Anolis ecomorphs according to the predominant microhabitat (e.g. grasses, open ground, different parts of trees) of the respective Anolis : crown giant, trunk-crown, trunk ...
Anolis is a genus of anoles (US: / ə ˈ n oʊ. l i z / ⓘ), iguanian lizards in the family Dactyloidae, native to the Americas.With more than 425 species, [1] it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 Anolis species remain.
There are three species that have been documented to be preying on the Anolis aquaticus: one species of crab and two species of bird. [16] When threatened, the Anolis aquaticus partakes in a combination of surface swimming and "scuba diving". These anti-predatory behaviors allow this lizard to migrate between the banks and boulders of its ...
This adaptation occurred in just 20 generations. [177] Anoles are also adapting to life with humans: Puerto Rican crested anoles living in cities have developed more adhesive lamellae on their toe pads than ones living in forests, reflecting the need for being able to climb very smooth surfaces like windows in the former habitat. [61]
The genus Anolis is part of the larger family Dactyloidae of anoles. This is an example of convergent evolution where lizards on different islands with similar habitats may evolve to share similar morphologies. [6] Within the genus Anolis, A. evermanni is classified in the trunk-crown ecomorph, generally living in the upper trunks and canopies ...
Anolis trachyderma (Cope, 1876) – common forest anole, roughskin anole Anolis transversalis (Duméril, 1851) – banded tree anole, transverse anole Anolis trinitatis (Reinhardt & Lütken, 1862) – St. Vincent Bush anole, Saint Vincent's bush anole, Trinidad anole
Anolis gundlachi, also commonly known as the yellow-chinned anole, Gundlach's anole, and the yellow-beard anole, is an oviparous, sexually dimorphic species of lizard in the family Dactyloidae. The species is endemic to Puerto Rico and lives in mountainous forests at high elevations. [2] The diet of A. gundlachi consists mostly of insects. This ...
In Puerto Rico, Anolis is represented by 10 separate species. All share adaptations to live primarily arboreal, diurnal lives, while being insectivorous. In comparison to all other Puerto Rican anoles, A. occultus is smaller in size and has a smaller, elongated head. The scales of the head are much smaller in this lizard.
