A baby hummingbird hatches. But it has fluffy feathers on its back, looking just like a dangerous caterpillar. Could this be something unusual among hummingbirds?
Blue whales, the largest animals on Earth, travel hidden ocean highways.
Data collected on juvenile and adult fringe-lipped bats reveal the first clues into the development of eavesdropping behavior in predators
Did you know that there are more than 20,500 species of bees, each with its own natural history?
Observations of Coiba’s tool-using immature capuchin monkeys show them carrying abducted infant howler monkeys. What is the reason for this behavior?
Have you ever wondered how city life affects animals like frogs? A new study reveals that urban Túngara frog tadpoles develop faster —but end up being smaller — than tadpoles from forests, probably resulting in smaller adults. This might be an adaptation to warmer urban puddles with fewer predators or to constantly changing environmental conditions in the city.
A groundbreaking study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished —doubling in numbers and growing larger. This unprecedented look into prehistoric reef communities shows how the loss of top predators cascaded through the entire food web, shifting the balance amongst coral reefs.
