A zebrafish view of the world has been forensically analysed by researchers at the University of Sussex to reveal that how they see their surroundings changes hugely depending on what direction they are looking.
Certain types of tapeworm make sticklebacks behave carelessly and thus become easier prey for birds. A team of biologists have now demonstrated for the first time that the tapeworm not only influences the behavior of the infected fish -- indirectly, it can also induce risky behaviour in other fish in the group.
Researchers at the University of Montana recently discovered that hybridization played an important role in snowshoe hares' ability to match their environment.
African weakly electric fish, commonly called baby whales, use incredibly brief electrical pulses to sense the world around them and communicate with other members of their species. Part of that electrical mechanism exists in humans -- and by studying these fish, scientists may unlock clues about conditions like epilepsy.
A remarkably high diversity of goblin spiders is reported from the Sri Lankan forests by two researchers from the National Institute of Fundamental Studies, Kandy, Sri Lanka. Nine new species are described in a recent paper in the open-access journal Evolutionary Systematics, where six are named after goblins and brownies from Enid Blyton's children's books. There are now 45 goblin spider species belonging to 13 genera known to inhabit the island country.
Humans and other primates are outliers among mammals for having nails instead of claws. But how, when and why we transitioned from claws to nails has been an evolutionary head-scratcher.
Dinosaurs are often depicted as fierce creatures, baring their teeth, with tongues wildly stretching from their mouths like giant, deranged lizards. But new research reveals a major problem with this classic image: Dinosaurs couldn't stick out their tongues like lizards. Instead, their tongues were probably rooted to the bottoms of their mouths in a manner akin to alligators.
By faithfully copying the most popular songs, swamp sparrows create time-honored song traditions that can be just as long-lasting as human traditions, finds a new study. The results show that creating traditions that pass the test of time doesn't necessarily require exceptional smarts.
American swamp sparrows may have sung the same songs for more than 1,000 years and passed them on through generations by learning, according to researchers at Queen Mary University of London, Imperial College London and Duke University.
A new computational tool will potentially help geneticists to better understand what makes a human a human, or how to differentiate species in general, by providing more detailed comparative information about genome function.
