Researchers at the Massachusetts Institute of Technology, USA, have developed innovative water filters by taking inspiration from the feeding methods of mobula rays. Researchers conducted a detailed analysis of how mobula rays feed on plankton in seawater and found that their feeding technique enables them to retain the tiny plankton while allowing the water in their mouth to escape. This specialised technique also allows them to breathe while feeding. The study revealed that these aquatic creatures have structures in their mouth, which resemble combs. These structures, called plates, lead to the formation of vortices when the creatures swim, enabling them to capture plankton. Scientists have replicated this technique to develop water filters that can filter impurities generated from industrial processes
