Cuttlefish Camouflage Nanoscale Photonic Device
2014-01-29 11:58:08

[ Watch the Video: What Mechanisms Are Behind Cuttlefish Camouflage? ] Brett Smith for redOrbit.com - Your Universe Online Capable of producing zebra-like camouflage or ‘hypnotic’ color oscillations, the skin of the cuttlefish has long fascinated scientists looking to unlock its secrets. Now, a new study from Harvard University has revealed a natural nanoscale photonic device that allows the so-called 'chameleon of the sea' to dynamically change its colors. "Nature solved the...

Layers Of Color Cells Form Guppy's Spots
2014-01-24 10:11:10

Public Library of Science Multiple pigment cell types create black, blue, orange spots of the guppy At least three pigment cell types from multiple layers of skin contribute to the color patterns of male guppies, according to a study published in PLOS ONE on January 22, 2014 by Verena Kottler from the Max Planck Institute for Developmental Biology and colleagues. Female guppies select their mate based on the size and number of colorful spots on a male's body and fins. Orange, blue,...

Female Squid Have Two Ways To Switch Color According To Study
2013-09-19 11:30:34

University of California - Santa Barbara The female common market squid –– AKA Doryteuthis opalescens –– may not be so common after all. Researchers at UC Santa Barbara have discovered that this glamorous cephalopod possesses a pair of stripes that can sparkle with rainbow iridescence. These flank a single stripe, which can go from complete transparency to bright white. This marks the first time that switchable white cells based on reflectins –– the proteins responsible for...

Color Change Mechanism Squid And Octopi

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of California, Santa Barbara (UCSB) have discovered the mechanisms responsible for the dramatic color changes in underwater creatures such as the squid and the octopus. According to UCSB scientists, color in living organisms can be formed in one of two ways - pigmentation or anatomical structure. Structural colors are the result of the physical interaction between light and biological...

Squid Use 'Electric Skin' For Camouflage
2012-08-28 07:43:03

Watch the Video: Squid´s Remarkable Electric Skin Lee Rannals for redOrbit.com - Your Universe Online Squid and their relatives are notorious for being some of nature's best masters of disguise, but their trickery has, for the most part, remained a mystery until now. Scientists report that squid control their skin's iridescence through their nerves, manipulating the animal's spectrum of hues, as well as their speed of change. This research is the first time neutral control of...

Squid And Zebrafish Spark Camouflage Inspiration

University of Bristol researchers have created artificial muscles that can be transformed to mimic the camouflaging abilities of squid and zebrafish. The team demonstrated two individual transforming mechanisms that they believe could be used in "smart clothing" to trigger camouflaging tricks similar to animals observed in the wild. "We have taken inspiration from nature's designs and exploited the same methods to turn our artificial muscles into striking visual effects,"  Jonathan...

Researchers from the University of Bristol have created artificial muscles that can be transformed at the flick of a switch to mimic the remarkable camouflaging abilities of organisms such as squid and zebrafish. They demonstrate two individual transforming mechanisms that they believe could be used in 'smart clothing' to trigger camouflaging tricks similar to those seen in nature. The study is published today, 2 May, in IOP Publishing's journal Bioinspiration and Biomimetics, and is...

The major difference between plant and animal cells is the photosynthetic process, which converts light energy into chemical energy. When light isn't available, energy is generated by breaking down carbohydrates and sugars, just as it is in animal and some bacterial cells. Two cellular organelles are responsible for these two processes: the chloroplasts for photosynthesis and the mitochondria for sugar breakdown. New research from Carnegie's Eva Nowack and Arthur Grossman has opened a window...

Instant Camouflage Discovered In Two Cephalopods
2011-11-11 11:17:36

[ Watch the Video ] Scientists have discovered two deep ocean species of cephalopods, the octopus Japetella heathi and the squid Onychoteuthis banksii, that can go from transparent to opaque in the blink of an eye, a new study finds. This impressive camouflage swap, from both an octopus and a squid, is an adaptation that help keeps the species safe from different types of predators, Stephanie Pappas of LiveScience reports. The first predators that the cephalopods must be wary of are...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - A little striped fish has helped scientists begin to solve one of the biggest mysteries in biology -- which genes are responsible for differences in human skin, eye and hair color. The large, international team of scientists reported on Thursday that they had found a gene that makes African zebrafish of a lighter-than-normal color -- and say the same gene helps explain the light-colored hair, skin and eyes of...

Chameleons are small to mid-size reptiles that belong to one of the best known lizard families (Chamaeleonidae). They are famous for their ability to change their color also because of their elongated tongue and their eyes which can be moved independently of each other. The name "Chameleon" means "earth lion" and is derived from the Greek words chamai (on the ground, on the earth) and leon (lion). Distribution and habitat The main distribution of Chameleons is Africa and Madagascar,...
