True coral snakes of the genus Micrurus have small, fixed, grooved fangs rather than large movable ones. To deliver their potent neurotoxin, they must bite, hold on and make chewing movements.
Woodpeckers can strike hard tree trunks up to 20 times per second without suffering brain injuries. Their skull, bill, tongue and neck muscles work together as a natural impact-absorption system.
The Amazonian spider Nephila produces several kinds of silk and builds a web that combines remarkable strength, elasticity and impact absorption.
During the flood season, fish in the Amazonian igapó swim among submerged trunks and treetops, eating fruit and dispersing seeds. Their movement helps sustain the regeneration of the flooded forest.
The blue Morpho butterfly reflects sunlight through microscopic layers of chitin and air rather than blue pigment. Its structural color is also inspiring sensors, displays and sustainable materials.
The skin secretion of Phyllomedusa bicolor contains peptides being studied for their possible antidepressant effects. Researchers are seeking to turn Kambô molecules into compounds synthesized in the laboratory.
Brazilian researchers are studying how crotoxin, a protein from South American rattlesnake venom, can target tumor cells while sparing healthy tissue in controlled doses.
For 50 days of incubation, sand temperature determines whether Amazon turtle hatchlings develop as males or females. INPA researchers are tracking nests, migrations and the climate pressures affecting the species.
Quantum physics already powers everyday devices and could reshape environmental monitoring, biotechnology, solar energy and biodiversity protection in the Amazon.
Genetic analysis is uncovering Amazon snake lineages hidden beneath the appearance of familiar species. These cryptic species could reshape conservation, antivenom production and biodiversity research.
