The common coquí or coquí is a species of frog endemic to Puerto Rico belonging to the family Eleutherodactylidae. The species is named for the loud call the males make at night. This sound serves two purposes. "CO" serves to repel other males and establish territory while the "KEE" serves to attract females. Since the auditory systems of males and females respond preferentially to different notes of the male call, this is an example of a sex difference in a sensory system. The common coquí is a very important aspect of Puerto Rican culture, and it has become an unofficial territorial symbol of Puerto Rico.
The golden coquí is a rare species of frog endemic to Puerto Rico.
Cordillera Central, is the main mountain range in Puerto Rico. The range crosses the island from west to east and divides it into its northern and southern coastal plains. The Cordillera Central runs eastward from the municipality of Maricao in the west to Aibonito in the central eastern region, and on to the Caribbean in the southeast through the Sierra de Cayey. The Central Mountain Range consists of the Cordillera Central proper and numerous subranges, foothills and ridges that extend throughout the island. Cerro de Punta is both the highest peak of the Cordillera Central and the highest point in Puerto Rico. The Sierra de Luquillo, where El Yunque is located, is sometimes included as a subrange or eastward extension of the Cordillera Central.

The Puerto Rican rock frog, Eleutherodactylus cooki, also known as the Puerto Rican cave-dwelling frog or rock coqui, and locally as coquí guajón, or guajón for brevity, is a threatened frog species from the coqui genus. This unique species of tropical frogs dwells primarily in crevices and grottos in the Cuchilla de Panduras mountain range in southeastern Puerto Rico. The native name guajón is derived from its habitat, guajonales, which are caves formed by rock formations between huge stones. Despite being the state animal and considered emblematic of the region, of the 17 species of coquí, three are believed to be extinct and the rest are rare and declining in numbers. The Puerto Rican rock frog is extremely restricted in geographical distribution. The frog is threatened due to deforestation, agricultural, rural, and industrial development, and the associated infrastructure. It is sometimes called the “demon of Puerto Rico" because of its eerie call and phantom-like appearance. The species was first described by American herpetologist, Chapman Grant in 1932.
