In this video, we explore the mechanotransduction of dinoflagellates: tiny organisms that react to water movement. We examine how these cells behave like viscoelastic materials and how their bioluminescent response is governed by specific force thresholds, speeds, and depends on their surface area. The explanation is based primarily on the research of Tesson (2015), Jalaal (2020), and Letendre (2025), whose work allows us to bridge the gap between fluid mechanics and biological signaling. Understanding these physical principles is now essential for predicting the development of harmful algal blooms (HABs), providing a vital tool for protecting marine ecosystems and public health.
