Ameerega trivittata
Ameerega trivittata, also known as the three-striped poison frog, is a species of frog native to lowland forests and marshes in several South American countries. It is distinguished by its terrestrial, diurnal nature, granular skin, lack of webbing between digits, and prominent stripes that vary in color. The species is currently facing threats due to habitat loss.

About Ameerega trivittata
Ameerega trivittata, commonly recognized as the three-striped poison frog, is a species of frog native to the diverse ecosystems of South America. Its natural range encompasses Bolivia, Brazil, Colombia, Guyana, Peru, Suriname, and Venezuela, with potential presence also noted in Ecuador and French Guiana. This species typically inhabits the moist floors of subtropical and tropical lowland forests and can also be found in intermittent freshwater marshes.
Physical Characteristics and Behavior
The three-striped poison frog is characterized by its terrestrial and diurnal lifestyle, meaning it is active during the day and lives on the ground. Distinctive among its features are its relatively large size, reaching up to 50 mm in snout-to-vent length, its granular skin texture, and the complete absence of webbing between its digits. A prominent characteristic is its striking striped markings, which commonly appear in shades of green but can also manifest as yellow or orange, running from the snout to the hind legs. The frog's coloration typically includes a black back and sides, a black belly tinged with blue posteriorly, and limbs of a yellowish-green or light-brown hue.
Reproduction and Diet
Reproduction in Ameerega trivittata involves terrestrial egg-laying, with clutches deposited under fallen leaves. The male takes on a significant role in parental care, guarding the eggs for approximately 15 days until they hatch. Post-hatching, the male transports the tadpoles on his back to suitable ephemeral pools or water-filled crevices, where they undergo metamorphosis over a period of 41 to 54 days. The primary diet of this species consists of ants, which are readily available in its forest floor habitat.
Conservation Concerns
Currently, Ameerega trivittata is classified as threatened, primarily due to habitat loss. The degradation and destruction of its natural forest and marsh environments pose a significant risk to its population survival.
