The Puerto Rican rock frog is threatened by deforestation, construction and industrial development, runoff from the use of pesticides and fertilizers in agriculture, the use of caves as garbage dumps, and fire. It is a habitat specialist, meaning it is adapted to particular environmental conditions, and abrupt changes in these conditions could ...
Eleutherodactylus portoricensis (vernacular Spanish: coquí de la montaña) is a frog native to Puerto Rico that belongs to the family Eleutherodactylidae. [2] [3] Its vernacular English names are forest coquí, upland coquí, mountain coquí, and Puerto Rican robber frog.
This protected natural area is one of the last habitats of the rare, endemic and endangered Puerto Rican rock frog (Eleutherodactylus cooki) also known as the rock coqui or the coquí guajón in Spanish. This small species of frog dwells primarily in crevices and grottos (habitats which are locally known as guajonales) of the Sierra Pandura. [1]
Eleutherodactylus coqui, the most well-known species. Coquí is a common name for several species of small frogs in the genus Eleutherodactylus native to Puerto Rico.They are onomatopoeically named for the very loud mating call which the males of two species, the common coqui and the upland coqui, make at night.
Common coquís are native to the islands of Puerto Rico, Vieques and Culebra, where they are widespread and abundant; the only notable exception occurs in Puerto Rican dry forests, where the species is rarer. The common coquí is the most abundant frog in Puerto Rico, with densities estimated at 20,000 individuals/ha. [8]
Kirtisinghe's rock frog (Nannophrys marmorata), a frog in the family Dicroglossidae endemic to Sri Lanka; Masked rock frog (Litoria personata), a frog in the family Hylidae endemic to Australia; Puerto Rican rock frog (Eleutherodactylus cooki), a frog in the family Leptodactylidae found in Puerto Rico
Many species (for example, Cook's robber frog, E. cooki), also of Puerto Rico, exhibit sexual dimorphism in size and color. Study on Eleutherodactylus and Lithobates amphibians shows that number of offsprings instead of body size may help to find which species require conservation from being extinct.
The frog is the smallest of its genus in Puerto Rico, with a snout-to-vent length of 14.7 millimetres (0.58 in) in males and 15.8 millimetres (0.62 in) in females. It has extensive dorsal skin glands. The prominent nares (nostrils) have a ridge that connects behind the snout tip, giving the nose a squared-off appearance.
