In a recent study from Nagoya University in Japan, researchers found scale-eating cichlid fish from Africa’s Lake Tanganyika become either right-handed or left-handed as the mature. It is believed that such specialization gives the fish an evolutionary advantage.
Sharks have a reputation for having large appetites, but it appears that reef sharks are remarkably light eaters. After pumping the stomachs of black-tip, white-tip and grey reef sharks, researchers found the animals eat small meals infrequently and opportunistically.
We've all heard about how noise pollution negatively impacts marine environments. But a recent study suggests that motor boats, rather than large cargo ships, easily stresses young damselfish which ultimately gives their predators the upper hand.
Audubon's recent "BirdNote" podcast explains the peculiar head movements of owls. No, it's not just to creep out humans. There's a good reason for all that staring, twisting and bobbing.
Reed warblers have set up a "neighborhood watch" to protect their nests from invasive cuckoos, who lay their eggs in local nests for others to raise. When reed warblers spot a cuckoo, they mob it and emit alarm calls that alert neighbors a cuckoo is at large and they should monitor their eggs closely. This has greatly benefited warblers, but cuckoo populations appear to be suffering.
It seems obvious that camouflage helps animals survive in the wild, but it is a relatively hard thing to test in the wild. A recent study, however, confirms this long-held assumption, proving that disguising one’s body or eggs to match the environment deters predators.
Pederson's cleaner shrimp bodies are almost completely transparent. However, when these tiny shrimp exercise, or give a few tail flips, their bodies turn opaque, revealing them to predators.
Secretary birds are able to kill their prey with one swift kick, exerting a force five times their own body weight. This is particularly advantageous for these lanky-legged birds that hunt venomous snakes -- because a missed kill could have deadly consequences.
Not all lizards are able to change the color of their skin to blend in with their surroundings. Therefore Aegean wall lizards, for example, camouflage by choosing rocks that best match the color of their backs, thus ensuring they are able to remain hidden from avian predators.
Hagfish secrete a slime that researchers hope to harness and make into super hydrogels, or new super-absorbent materials that can be used in plasters and baby diapers.
Sea slugs have colorful patterns to ward off predators -- but when that doesn't work they defend themselves using toxic chemicals they gather from their environment.
Researchers discovered that carnivorous plants such as the Venus flytrap can count. This is likely their way of avoiding false alarms and making sure they have captured a juicy bug before releasing their digestive enzymes.
Apparently lions and hyenas on African savannahs are not at all fazed by zebra stripes, according to a new study from UC Davis and the University of Calgary, in Canada.
Snowshoe hares typically shed their brown summer coats to blend in with the snowy scenery of the winter. However, when there is no snow, these mismatched animals have no place to hide and increase their chances of being spotted by a predator.
An extinct marine crustacean-like creature known as Dollocaris ingen was equipped with two large eyes, each about a quarter of its body size. Researchers say this likely gave the pipsqueak an advantage when ambushing its prey.
