The importance of prawns in organismal research is an issue of concern due to their multifaceted and unique biological characteristics. This majorly includes their tolerance to critical environmental situations, sensitivity, exceptional body morphometrics, ecogeographic occurrence and diversity. All of these make prawns a highly adaptable and evolutionary successful organism. While studying the biology of a freshwater prawn species, Macrobrachium lamarrei, we have encountered the fact that prawns being evolutionarily successful, manifest tolerance and adaptability in changing environmental conditions. Where global climate change is an issue of concern for researchers, phenotypic expositions in animals for combating the evolution of the planet is also a brainstorming matter for evolutionary biologists. Our model organism manifested tolerance to critical eco-contamination and on the other hand, exhibited sensitivity, behavioural plasticity and profound ecogeographic occurrence. Ecogeographical aspects of this species in terms of ecotoxicological issue are correlated in respect to the adaptational success. We have used Macrobrachium lamarrei as a model prawn species to highlight the prawn group to get more attention in organismal and environmental research. Through this article, we want to raise this question of why we are not re-scrutinizing the biological complexities of prawns in terms of behavioural manifestations.
