Researchers found that moths search for a spot to rest and adjust their body orientation to become nearly invisible to birds. The insects' behavior suggests they have an active choice of a resting spot that makes them visually camouflaged.
Researchers used image analysis software to determine that octopuses reproduce specific features of objects in their surroundings for effective camouflage. This strategy may make the approach more flexible and increase success in different environments.
Scientists develop transforming mechanisms inspired by nature to create camouflage effects in soft, stretchy materials. The technology can be used in smart clothing, scaling up to an adaptable skin that stretches and deforms.
Smalleye pigmy sharks use light-emitting photophores on their undersides for camouflage, unlike lantern sharks that use bursts of glowing light for communication. The discovery suggests the smalleye pigmy shark is more closely related to an ancient predecessor with similar bioluminescence mechanisms.
Researchers have developed a simple technique to teach civilians to break camouflage, with 60% of volunteers achieving proficiency in just two weeks. The Army is using this method to improve its sniping skills, and researchers are studying the brain activity involved.
Two species of deep-sea cephalopods have the ability to rapidly switch between transparency and a dull red color as optical conditions change, providing an adaptive camouflage strategy. This 'switchable' camouflage is highly advantageous for survival in the unique environment of the deep sea.
Dazzle camouflage, a World War I technique, can affect perception of speed when objects move quickly, potentially reducing losses from attacks on fast-moving vehicles. This effect is due to high contrast geometric patterns, which were found to cause a significant reduction in perceived speed by around 7 percent.
A team from MBL and West Point used hyperspectral imaging to model cuttlefish camouflage in the eyes of fish predators, revealing that brightness is more important than color. This study provides strong evidence that cuttlefish can produce effective camouflage despite lacking color vision.
A team of scientists, led by Roger Hanlon and Naomi Halas, aims to emulate the camouflage ability of squid, octopus, and cuttlefish in high-tech materials. They will explore new avenues of vision research, including distributed light sensing throughout the skin.
Researchers found that caterpillars position themselves in areas with abundant twigs during the day to avoid detection, but switch to richer feeding grounds at night. This complex behavior shows that masquerading prey use habitat-selection strategies to exploit predators' hunting behavior.
Researchers discovered that barred patterns on birds' feathers play a crucial role in sexual signaling, particularly on the front of males during face-to-face interactions. The study, published in Journal of Evolutionary Biology, provides insight into bird communication and evolution.
Researchers have discovered a key ingredient in animal color patterns: a diffusible protein called Wingless. This morphogen prompts cells to make pigment, creating intricate designs like stripes and spots. The study's findings have implications for understanding how animals evolve their color patterns.
Atlantic longarm octopuses have evolved expert camouflage capabilities, including mimicking the appearance and swimming speed of peacock flounders. Researchers observed uncanny similarities in coloration, form, and movement between the two species, demonstrating an unusual form of disruptive camouflage.
A rare woodland plant, Monotropsis odorata, has evolved 'cryptic coloration' as a defense mechanism to avoid herbivores. The plant's bracts function as camouflage, making it blend in with its surroundings, which increases its fitness and survival rate.
Researchers will build an underwater virtual reality 'holodeck' to study cephalopod camouflage, measuring light fields and behavior in different environments. The goal is to understand the nature of their vision, color perception, and skin optical properties.
Researchers have identified three broad classes of camouflage body patterns in animals, including uniform, mottled, and disruptive coloration. These patterns are used by cephalopods to dynamically produce a wide range of visual disguises, making them one of the most changeable animal groups on earth.
Chameleons use dramatic color changes to display to conspecific competitors and seduce potential mates. The study found that the degree of color change is associated with social signaling, not camouflage, challenging the long-held camouflage hypothesis.
Researchers at Harvard University identified the genetic changes responsible for lighter fur coloration in beach mice, which helps camouflage them from predators. The discovery sheds light on how specific gene interactions can influence an organism's appearance and survival.
Researchers have confirmed that cuttlefish employ night camouflage to adapt quickly to microhabitats on temperate rock reefs. The ability is key to their nighttime predator/prey interactions and fine-tuned visual system, allowing them to dominate the dark environment.
Researchers from MBL found anatomical evidence of a 'hidden communication channel' in squid skin, which remains masked during camouflage. The study suggests that squid may use polarized signals to convey information about their surroundings, including the presence of predators or other squid.
Researchers found cuttlefish can detect contrast differences of at least 15%, suggesting they use intensity matching for camouflage. The study's findings shed light on the complex visual processing of these cephalopods, an ideal model for studying camouflage.
This study reveals that consumers store and camouflage brand products in their households, creating a new understanding of American consumerism. The findings challenge traditional assumptions about the significance of brands, highlighting the importance of household processes over individual identity.
Scientists have observed glowing coral reefs when illuminated with blue light, which could be used to map specific coral groups within a reef. This phenomenon is related to species and coral health, providing a potential tool for managing sensitive military areas and detecting man-made objects.
