Males of a newly discovered species of jumping spiders have been filmed playing peek-a-boo with potential mates. Not all females are receptive to this playful courtship -- females who have mated before will chase off suitors while virgin females hook-up almost immediately.
After delving into the brain of the zebra finch, researchers revealed how the birds are able to learn the courtship songs sung by their fathers. It turns out they have specialized nerve cells that allow them to memorize one note at a time.
Fish chatter with each other in order to stay close to one another and better their chances of safety. While contact calls are generally used for mating purposes or to defend one's territory, this is the first time researchers have observed fish communicating to maintain group cohesion.
A new experiment revealed that capuchin monkeys will punish other monkeys who have been given more food. Yale researchers say this is the first evidence suggesting that the psychology of spite extends deeper into our evolutionary history than previously thought.
Male Brazilian torrent frogs perform interesting dance routines using their toes, feet, hands, legs, arms, vocal sacs, head, and body to attract a mate. Researchers say these diverse visual and audio displays are unlike any others they have observed in frogs.
The noisy claw sounds of snapping shrimp may be a good indication of reef health, researchers say.
Using a special SharkCam, researchers have filmed the underwater predatory behaviors of great white sharks for the first time. It appears they lurk in the darkness before ambushing their prey from below. While this new study offers groundbreaking insight, researchers say there is still much to learn about these mysterious fish.
A mother's diet is largely responsible for keeping animal populations in check, according to a new study from the University of Edinburgh
Among the insects known as burying beetles, females are more attracted to smaller males because they are, you know, chill. That is, they're less likely to get into fights when competing for mates. Despite their increased sex appeal, however, smaller males are not necessarily better parents, researchers reveal in a new study.
Along with visual camouflage, Puff adders have evolved a scent camouflage that makes them virtually undetectable to predators. Researchers say these African vipers are the first terrestrial vertebrates known to possess the ability to camouflage their scent.
In a 2014 survey of Morocco's island of Mogador, raptors called Eleonora's falcons were observed engaging in a what researchers called a new behaviour that ensures their offspring receive the freshest of meats: imprisoning smaller live birds before killing and feeding them to their young several days later.
Crows are frequently observed gathering around dead comrades. When researchers from the University of Washington investigated this behavior they found the crafty birds understand much about death and the threat of death by predators, not only reacting to their fallen brethren but also avoiding areas or things they deem dangerous.
In an act of choosing to lose the part but not the whole, a certain type of sea slug severs its back appendage to leave a predator holding the bag--or body part, as it were, according to a new study. Knowledge of how they do this could potentially lead to medical breakthroughs in helping wounds to heal.
Paleontologists suggest recently discoverd foot scrapes across several Colorado outcrops were made by large dinosaurs that competed in dance-offs to woo their mates.
Carpenter bees engage in dogfighting-like behaviors to defend their hives and prevent other bees from laying eggs in their carefully-constructed homes. Using a GoPro, researcher Dr. Brandon Jackson of Longwood University recently filmed the bee's rather unique aerial combat style.
