Tiny marine snails known as sea butterflies appear to "fly" underwater much like winged insects do when taking to the sky – representsing a remarkable example of convergent evolution, where two unrelated species develop features that are used in similar ways.
Prehistoric claw marks found inside Australia's Tight Entrance cave reveal a bit more about the continent's extinct predator, the marsupial lion. It turns out the animals were agile hunters that reared their young inside the cave.
Researchers have for the first time modeled how locusts behave in swarms. Their findings may ultimately help disrupt swarms and curb the environmental devastation of a locust invasion.
When leaving their nests in the morning, wasps look back on their nests to take in distinct land markings to ensure they can find their way home after flying about all day searching for food.
Inhibitory control, or the ability to wait for a treat, may be a good indicator of how well your pooch can solve a problem.
Like bees, ants organize their colonies based on social rank. It appears trap-jaw ants engage in antenna-boxing matches to dictate who guards the colony and who goes out into the world to forage.
Advanced tagging technology has captured never-before-seen data on how deep beluga whales will dive for food. Researchers say their foraging patterns are largely based on the abundance of Arctic cod and sea-floor topography.
Chimpanzees are less inclined to groom one another with numerous bystanders lingering about. This challenges the long-held belief that such cooperative behaviors are based on trust, suggesting they revolve more around immediate benefits.
Nature World News has a long list of animals you might want to avoid -- lest they sting, electrocute, or fatally bite you. This is just a sampling.
A total of 98 shark attacks were reported in 2015, six of which were fatal. This total breaks the previous record of 88 attacks in 2000.
Thousands of blacktip sharks in a huge congregation were recently caught on-camera in South Florida.
When shown pictures of an unfamiliar human with a threatening facial expression, horses become stressed and view the image using their left eye. While similar behaviors have been documented in domestic cats and dogs, this is the first time researchers have found horses can interpret the different emotions of their handlers, too.
Amazed by the sneaky and speedy ability of cockroaches, researchers created a bio-inspired robot that could one day be used to search through rubble in disaster zones and free victims.
Using a specialized IQ test, researchers examined the "general intelligence" of border collies. Since dogs and people have a lot in common, researchers suggest their findings could lead to improved diagnosis and treatment of human disorders, such as dementia.
