Lifting the cloak of invisibility: the effects of changing optical conditions on pelagic crypsis.
While transparency, cryptic coloration, and counterillumination are all highly successful cryptic strategies for pelagic species, they become less effective when confronted with varying optical conditions. Transparent species are susceptible to detection by reflections from their body surface, particularly at shallow depths. Colored and mirrored species are vulnerable to detection when viewed f...
متن کاملCryptic and conspicuous coloration in the pelagic environment.
Despite the importance of cryptic and conspicuous coloration in pelagic ecosystems, few researchers have investigated the optimal reflectance spectra for either trait. In this study, the underwater radiance distribution in tropical oceanic water was modelled using measured inherent optical properties and radiative transfer calculations. The modelled light field was then used to predict the refl...
متن کامل14: Dynamic Camouflage in Benthic and Pelagic Cephalopods:An Interdisciplinary Approach to Crypsis Based on Color, Reflection, and Bioluminescence
Our overall goal is to understand the perceptual and mechanistic principles that underlay camouflage framed in the context of the animals' environment. In particular, we hope to characterize and understand the perceptual abilities of several species of benthic and pelagic cephalopods, the aspects of their optical environment that affect their camouflage behavior, the characterization of that be...

متن کاملThe selective advantage of crypsis in mice.
The light color of mice that inhabit the sandy dunes of Florida's coast have served as a textbook example of adaptation for nearly a century, despite the fact that the selective advantage of crypsis has never been directly tested or quantified in nature. Using plasticine mouse models of light and dark color, we demonstrate a strong selective advantage for mice that match their local background ...
