Diasporus diastema

Common Tink Frog

Taylor, 1955

Detailed Texts Multi-lang
A tiny anuran with a delicate and slender body. It has a variable base coloration that usually ranges between yellowish tones, light green, or brown, often with a pale vertebral line that helps break up its silhouette among the leaves. Its fingers have prominent adhesive disks, adapted for a semi-arboreal life.

Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Inhabits the understory and lower levels of vegetation in humid forests and premontane forests. It is common to find it in bromeliads and other epiphytic plants that retain water, vital for its microhabitat.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

Mostly nocturnal species. It is active for much of the night, moving with agility among the humid vegetation. Its song is most frequent after rains, when environmental humidity is optimal.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Solitary, except during the breeding season. Males occupy small patches in epiphytic plants from where they emit their songs to attract females and defend their territory from other males.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Active micro-prey hunter. Uses binocular vision and its protractile tongue to capture small prey with great precision, taking advantage of plant surfaces as hunting platforms.

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Insectivore. Feeds on a wide variety of micro-arthropods that inhabit bromeliads and the lower canopy, including mites, springtails, and small ants.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Oviparous with direct development. Females deposit their eggs in water-filled bromeliads or protected tree holes. No extensive parental care has been recorded after laying.

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.

Males Multi-lang

Males are significantly smaller, with vocal sacs clearly visible when inflated. Their behavior is more active in terms of defensive and territorial vocalizations.

Females Multi-lang

Females possess a larger size, with a wider and heavier body structure to facilitate the production of their eggs. They are less vocal than males in their daily behavior.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Metallic Vocalization: Males possess an expandable vocal sac that allows them to emit a song reminiscent of metal striking metal, an adaptation to communicate effectively in environments with a lot of environmental insect noise.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Environmental Sensitivity: As small species with highly permeable skin, they are extremely sensitive to desiccation and changes in water quality, making them excellent bioindicators of forest health.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

Direct Development: Like many frogs in its family, the tink frog avoids the tadpole phase. Its eggs are deposited in bromeliads, where embryos complete their development until emerging as tiny froglets.
