Anolis eugenegrahami, the Eugene's anole or the black stream anole, is a critically endangered species of lizard in the family Dactyloidae. [1] This semi-aquatic species is endemic to northern Haiti. [3]
The specific name, eugenegrahami, is in honor of herpetologist Eugene D. Graham Jr., who was one of the collectors of the holotype. [4]
A. eugenegrahami is endemic to the Département du Nord in northern Haiti where it is only found 9 kilometres (5.6 mi) northeast of Plaisance. [3] It strictly inhabits stream margins in areas with forest. [1]
This species, A. eugenegrahami, is of moderate size, with extremely long limbs. [5] Males can reach up to 72 mm (2.8 in) in snout–vent length and females up to 61 mm (2.4 in). Males and females are both very dark. The dewlap (male only) ranges from very dark gray to black, with the edge being lighter. [3]
It is one of two semi-aquatic anoles from the Caribbean, the other being A. vermiculatus of Cuba, and there are a few additional semi-aquatic anoles in Central and South America. [5] [6] The semi-aquatic anoles are morphologically diverse and do not form a monophyletic group, [5] but there is convergence in certain microstructures of their skin, making it highly hydrophobic. [6] This results in a thin layer of air on the skin surface when submerged underwater, which they use as an extra air supply for breathing, and it also prevents water from staying on when exiting the water. [6] [7]
Dactyloidae are a family of lizards commonly known as anoles and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloinae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with Polychrus, but the latter genus is not closely related to the true anoles.
Anolis carolinensis or green anole is a tree-dwelling species of anole lizard native to the southeastern United States and introduced to islands in the Pacific and Caribbean. A small to medium-sized lizard, the green anole is a trunk-crown ecomorph and can change its color to several shades from brown to green.
The brown anole, also known commonly as the Cuban brown anole, or De la Sagra's anole, is a species of lizard in the family Dactyloidae. The species is native to Cuba and the Bahamas. It has been widely introduced elsewhere, via the importation and exportation of plants where the anole would lay eggs in the soil of the pots, and is now found in Florida and as far north in the United States as southern Georgia, Texas, Louisiana, Tennessee, Mississippi, Alabama, Hawaii, and Southern California. It has also been introduced to other Caribbean islands, Mexico, and Taiwan.
Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles. The species is native to Puerto Rico and the U.S. and British Virgin Islands, with introduced populations in locations around the Caribbean. The males of A. cristatellus are easily recognizable by the fin running down the top of the tail, which is known as a "caudal crest". The females also have this crest, but it is smaller than that of the males. The species is often quite common in many areas on Puerto Rico, where it can be seen during the day passing the time on the lower parts of tree trunks, or on fences and the walls of buildings in urban areas, sometimes venturing down onto the ground in order to lay eggs, have a snack, or do other cursorial activities. Like many anoles, this species displays the characteristic behaviour of doing push-ups as well as inflating a pizza-like flap of coloured skin on its throat, known as a dewlap, in order to show others how dominant it is, and thus attract mates or intimidate rivals.
Anolis garmani, also known commonly as the Jamaican giant anole, the Jamaican anole, and the Jamaica giant anole, is a species of lizard in the family Dactyloidae. The species is endemic to Jamaica, but has been introduced to Florida.
Anolis allisoni, also known commonly as Allison's anole or Cuban blue anole is a species of lizard in the family Dactyloidae. The species is endemic to Cuba, the Bay Islands and Cayos Cochinos off the mainland of Honduras, and Half Moon Caye off the mainland of Belize. There is also a single doubtful record from Cozumel, Mexico. Recently, the species has been documented in southern Florida. This diurnal species is commonly seen on palm trunks, and it feeds on invertebrates. It is among the relatively few anole species in which females may lay their eggs together, forming a communal nest.
Anolis bartschi, also known commonly as the Pinar Del Rio cliff anole, western cliff anole, and the west Cuban anole, is a species of lizard in the family Dactyloidae. The species is endemic to Cuba.
Anolis sabanus, the Saba anole or Saban anole, is a species of anole lizard that is endemic to the island of Saba, a Dutch municipality in the Caribbean Lesser Antilles.
Anolis luciae, also known commonly as the St. Lucia anole or Saint Lucian anole, is a species of anole lizard in the family Dactyloidae. The species is endemic to Saint Lucia, an island-nation in the Caribbean Lesser Antilles.
Anolis trinitatis, also known as Saint Vincent bush anole, Saint Vincent's bush anole, or the Trinidad anole, is a species of anole lizard found in the Caribbean.
Anolis richardii, commonly known as the Grenada tree anole or Richard's anole, is a species of anole lizard in the family Dactyloidae. The species is found in the Caribbean.
Anolis cuvieri is a species of lizard in the family Dactyloidae. The species is endemic to Puerto Rico, and is common in the Toro Negro State Forest.
Anolis podocarpus is a species of anole lizard in the family Dactyloidae. It was first described by Fernando P. Ayala-Varela and Omar Torres-Carvajal in 2010, the type locality being the Podocarpus National Park at Romerillos Alto in Zamora-Chinchipe Province, Ecuador on the southeastern slopes of the Andes. The specific name refers to the Podocarpus trees which are found in the Park.
Anolis poncensis is a species of lizard of the family of Dactyloidae. The species is endemic to Puerto Rico. It was first identified in Ponce, in the hills three miles east of the city. The Puerto Rico Department of Natural and Environmental Resources considers it a "vulnerable species".
The Vinales anole, also known as the Cuban stream anole, is a species of lizard in the family Dactyloidae, endemic to Cuba.
Anolis aquaticus, commonly known as the water anole, is a semi-aquatic species of anole, a lizard in the family Dactyloidae, native to southwestern Costa Rica and far southwestern Panama. The species demonstrates adaptations that allows it to spend periods of time underwater up to approximately a quarter of an hour, forming an air bubble which clings to its head and serves to recycle the animal's air supply while it spends time beneath the surface. Although highly unusual, similar adaptions and behavior are found in other species of semi-aquatic anoles.
Anolis christophei, also known commonly as the big-fanned trunk anole and the King Christophe anole, is a species of lizard in the family Dactyloidae. The species is endemic to the island of Hispaniola.
Anolis darlingtoni, also known commonly as Darlington's anole and the La Hotte twig anole, is a species of lizard in the family Dactyloidae. The species is endemic to Haiti.
Anolis evermanni, also known commonly as the emerald anole, Evermann's anole, and the small green anole, is a species of lizard included within the family Dactyloidae. A. evermanni is native to Puerto Rico, where it is mainly found in wet forests. A. evermanni is a medium-sized lizard and bright emerald-green in color. A. evermanni is studied for its behavior as well as the evolution of the family Dactyloidae. The group of lizards which are member species of the family Dactyloidae are known as anoles. Anoles are found throughout the Americas and are related to iguanas.
Anolis juangundlachi, also known commonly as the Finca Ceres anole and the yellow-lipped grass anole, is a species of lizard in the family Dactyloidae. The species is endemic to Cuba.
