Eleutherodactylus auriculatus is a tiny frog, with adult males measuring up to 20 mm and females to 24 mm in SVL. Digital discs are developed. There is no webbing between the toes. The vomerine teeth, behind the choanae, are present in an oblique series (Cope 1862; Bogart 1981; Ruiz 1987; Schwartz and Henderson 1985; Schwartz and Henderson 1991).

This frog is dark brown to tan or light gray, with the sides darker than the dorsum. A dark bar runs across the back and above the insertion of the forelimbs. Some individuals have a median dorsal light stripe. A brown to black line descends from the upper orbit to near the shoulder, crossing the upper part of the tympanum. The loreal region is black. A blackish band extends between the eyes. The hind limbs are dark with the concealed surfaces brownish in color. The venter is vivid yellow; the vocal sac is greenish with black dots (Cope 1862; Bogart 1981; Ruiz 1987; Schwartz and Henderson 1985; Schwartz and Henderson 1991).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Cuba


View distribution map in BerkeleyMapper.
This species is endemic to Cuba and Isla de la Juventud. It is found island-wide, from sea level to about 1400 m, occurring in forests (Schwartz and Henderson 1991).

Life History, Abundance, Activity, and Special Behaviors
Adult frogs are active throughout the day, although more activity is common at night (Fong unpublished). Males vocalize from shrubs, tree trunks and branches, vines, leaves, dead stumps and sometimes from the ground (Schwartz and Henderson 1991; Fong unpublished). Calls are similar to a flat telegraphic clicking, often with a few warm-up clicks, and composed of one note repeated continuously in close regular intervals (229-276 calls/minute). The dominant frequency is about 3.8-3.9 kHz (Schwartz 1969; Schwartz and Henderson 1991; Hedges et al. 1992; Estrada and Hedges 1997).

This frog is a direct developing species. Clutches consist of about 20 eggs, and are deposited in bromeliads or on the ground (Schwartz and Henderson 1991).

Trends and Threats
Clear-cutting of the forest, agriculture, infrastructure development for tourism and human settlement and disturbance of the forest by tourists are the main threats to this species (Hedges and Diaz 2004). Some natural areas in eastern Cuba have been degraded and substituted by coffee plantations, timber forests and pastures, causing the extirpation of this species from its original habitat (Fong 1999).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
