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.
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.
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.
Despite the lack of maternal care, young orphaned earwigs grow big and strong. However, like their mothers, they too are likely to care less for their offspring.
Captured damselfish release a chemical distress call that confuses their attackers by calling other predators to the area. The ensuing competition buys them enough time to flee.
While evolving with specialized defenses has helped animals escape predation, long-term risks need to be considered. The simple act of camouflage or mimicry, which sufficiently confuses prey, doesn't seem to have backfired, but the use of chemical defenses has. In fact, some amphibians that release lethal toxins to kill predators are now at a higher risk of extinction.
A hawksbill sea turtle found off the coast of the Solomon Islands is the first biofluorescent reptile ever discovered. The sea turtle was "glowing" green and red as it swam by researchers observing corals in the Pacific Ocean.
Bacteria have existed on the planet for quite some time, a lot longer than animals. It is because of their sophisticated arsenal that they have been able to live in this harsh world for this long. And recognizing their unique and effective warfare, some animals have chosen to steel bacteria's defense mechanisms, according to a new study.
An angry swarm of bees has always sounded scary, but what about an angry suicidal swarm of biting bees? Now that sounds like pure terror. A new study of Brazilian stingless bees has found that to defend their homes, these little guys will latch onto a threat and won't stop biting until they die.
No, trees and other leaved plants don't really have ears, but researchers have determined that they are sensitive to the vibrations of chewing insects, growing in a defensive manner when exposed to these alarming vibrations.
The world's first entirely 3D printed gun is here and its creator didn't want to keep the plans all to himself, and so instead, he posted it online for everyone and anyone. Within the first two days, 100,000 people have already downloaded the files, prompting the State Department to step in and order the removal of the blueprints.
