Crypsis in Nearshore Marine Habitats: Acquisition of Light Data and Images with Emphasis on Pattern and Edge Designs

Abstract

This proposal focused on the acquisition of digital images and video of cryptic marine animals in a variety of natural habitats, and under a wide range of lighting conditions. The research addressed a central question: what are the optical principles upon which crypsis is achieved by opaque organisms in shallow, nearshore marine habitats? Particular emphasis was placed on the designs of lines and edges in different types of cryptic patterning in cephalopods and fishes. Data were acquired by diving in shallow nearshore habitats such as coral reefs, kelp beds, rock reefs, seagrass meadows and sand plains. An eventual anticipated outcome is that certain bio-inspired designs of patterns in these images can find utility in refining concealment for naval materiel and personnel.
