Eleutherodactylus melacara is a small frog, with adult SVL reaching 36 mm in females and 29 mm in males. The body is flattened and the head is distinctly wider than the body, with a short snout. The canthus rostralis is slightly concave in dorsal view, and a canthal bar is only rarely present. The skin of the dorsum is weakly tuberculate, while the venter is moderately areolate. There is no webbing between the toes. The digital discs are large and conspicuous. The vomerine teeth are oval and posterior to the choanae (Hedges et al. 1992).

This species is greenish-brown dorsally without a distinct pattern (unicolor). The head is dark brown; the iris is dark brown below, bronze above. There is a faint brown supratympanic bar. The concealed surfaces of the thighs are dark brown. The venter is pale with some light brown flecks on the chin. This species exhibits an interesting color change (metachrosis) in life. When taken from bromeliads (where it lives), it has a distinctive dark brown snout that grades into a paler (tan) posterior body coloration. Within about 30 minutes, the dark anterior coloration disappears and the entire animal became uniform tan or light brown. (Hedges et al. 1992) .

Distribution and Habitat

This species is endemic to Cuba. It is known only from the Sierra del Turquino (Sierra Maestra mountains) in eastern Cuba. It occurs in rainforests and cloud forests above 850 m. This frog is one of the Cuban representatives of the bromeliad ecomorph (species that live nearly exclusively in bromeliads) (Hedges et al. 1992; Diaz et al. 2005).

Life History, Abundance, Activity, and Special Behaviors
During the day it can be found taking refuge in arboreal bromeliads 1-4 m above the ground. By night, specimens can be observed in exposed positions on bromeliad leaves or rarely on leaves of trees, above 2 m. Males vocalize from bromeliads, about 1 m above the ground, although sometimes they use sites below 1 m. Calls are a series of 14-22 hollow “tocks” with dominant frequency between 2.2-2.3 kHz. This frog is a direct developing species. Clutches are deposited within the bases of bromeliad plants. The clutch size is small (probably as few as 5 eggs, with 11 eggs/clutch observed). The eggs are very large, 6.9-9.3 mm in diameter (Hedges et al. 1992; Fong unpublished).

Trends and Threats
Habitat modification is considered the principal threat to this species (Vales et al. 1998). This species is threatened by habitat destruction as a result of deforestation due to agriculture, woodcutting, disturbance from tourists, and infrastructure development for human settlement (Hedges and Diaz 2004).

Possible reasons for amphibian decline

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