In the wild, every advantage counts. For sea creatures, it’s between the ones blessed with super sight and those who can seamlessly blend in the surroundings. Who wins? New research reported in Science Daily has the score.
The chameleon's tongue is super sticky that it can lift a prey three times bigger than its size.
The latest bio-inspired robot harnesses a chameleon's ability to quickly change color and blend in with their surroundings. While the robot is currently only able to change from red, to green, to blue, researchers are hopeful that with further study, they can someday create improved camouflage systems for military vehicles and body armor.
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.
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.
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.
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.
The corn snake's genome has been sequenced for the first time, and reveals important information regarding the gene mutation responsible for albinism.
Camouflage is a adaptable trait used not only to hide from predators, but to sneak up on prey. Researchers recently revealed horned praying mantises have re-evolved with disruptive camouflage abilities, similar to those found in ancient lineages of the iconic insects.
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.
Lizards use bright colors to attract mates but this also makes their camouflage less effective, making them visible to predators, report researchers from the University of Cambridge.
Australia, which is already home to a preponderance of the world's venomous snakes, is the home of a new species of Death Adder named the Kimberley death adder that uses it's tail to lure its prey.
Anyone familiar with bats knows that the term "blind as a bad" actually translates to "not blind at all." Not only do these animals have perfectly functioning eyes, but they also have the help of sonar in failing light. Now researchers have found a way to show what bats "see" with that echolocation, and the results have revealed some impressive findings.
