Animal camouflage techniques emphasise the effective ability to merge with the environment. This work efficiently demonstrates the reflection-refraction of light to show the biophysical method of camouflage in the underwater medium by a semi-transparent freshwater prawn, Macrobrachium lamarrei. The transparent tissue appearance of the body surface efficiently uses light intensity, regulates the degree of transparency. The goal of this research is to examine how body transparency and light interaction, efficiently manifests camouflagic adaptation in animals.
