The red piranha has the strongest bite relative to body weight among known fish. Its specialized jaws, social behavior and ecological role reveal an extraordinary form of biological engineering.
The king vulture opens the carcasses of large animals, allowing other scavengers to complete the forest’s natural cleanup. Its presence also signals a complex and healthy Amazonian ecosystem.
The harpy eagle can carry prey weighing up to 70% of its own body weight while maneuvering through dense forest. Its presence is also a powerful sign of a healthy Amazonian ecosystem.
The bushmaster is the largest venomous snake in the Americas, with extraordinary venom glands, specialized fangs and rare parental care. Its presence also signals the health of mature tropical forests.
Different schedules, prey preferences and microhabitats allow jaguars and pumas to share many of the same territories in Brazil’s forests. Their coexistence shows how evolution can reduce competition between two of the Americas’ largest cats.
The king vulture combines vivid head colors with a powerful bill to control access to carcasses and help other vultures feed. Its work also supports the health of Amazonian ecosystems.
The Amazonian vine snake can remain motionless for hours, matching the shape, color and texture of dry branches and vines. Its camouflage helps it ambush prey while avoiding larger predators in the forest canopy and understory.
The harpy eagle uses talons up to 5.1 inches long to capture sloths and adult monkeys in the canopy of Brazil’s forests. Its strength and flight reveal one of the Amazon’s most remarkable adaptations.
Dried droppings from pigeons, herons and parakeets can release fungi into the air. Inhaling those particles is linked to cryptococcosis and histoplasmosis.
Batista Campos Plaza became a permanent colony for hundreds of white egrets. Abundant food, nighttime lighting, large trees and a lack of predators help explain why the birds left mangroves and flooded areas.
