| Abstract | Dynamic Camouflage in Benthic and Pelagic Cephalopods: An interdisciplinary approach to crypsis based on color, reflection, and bioluminescence. We will be collecting Humboldt and various species of midwater squids using traditional jigging and trawling methods. Various physiology experiments investigating counter-illumination and squid chromatophore response will then be performed in the ship laboratories. We will also take samples for later microscopical and genetic analyses of the squid tissues responsible for camouflage. Concurrently, we will conduct detailed measurements of radiance and irradiance using custom-built, deployable light meters, using data-conducting cable from the ship J-frame. A deployable, custom-built omni-directional camera system, deployed either from a small boat or from the J-frame, will allow us to synthesize our data on camouflage response and light fields with the in-situ behavior of the animals. Performing these experiments in tandem will allow us to develop a model of open water camouflage synthesized from several hierarchical levels of physical organization and oceanographic knowledge. |
