The animal, typical of tropical forests in Central and South America, including Brazil, plays a fundamental role in the ecosystem and impresses with its striking appearance.
Arrow frogs are small, less than 1.5 cm in most species, but some reach 6.5 cm. Their vibrant colors — yellow, gold, blue, green, red, and even combinations — work to warn predators of toxicity.

The poison, present in the arrow frog’s skin, can paralyze and even kill predators. A golden specimen carries enough toxin to take the lives of ten adults. Indigenous tribes used this substance on arrowheads and darts to ensure success in hunting.
Amphibians feed on ants, termites and other small invertebrates, helping to control the insect population and preventing plant imbalance. Unlike what is seen in common frogs, the arrow frog is diurnal, circulating during the day in the forest.
Where is this frog in Brazil?
In Brazil, the highlight is the blue arrow frog, abundant in the northern Amazon forests. Even with its small size, the animal has enormous importance for nature and faces threats due to habitat degradation and hunting.
Those who want to see it up close can visit the São Paulo Zoo, the largest in Latin America, which also houses specimens of this rare and powerful species.
