A slimy layer of grey or green sludge formed when algae are overloaded with nutrients is called sea snot. It is a marine mucilage and is harmful to the water bodies. When algae are overloaded with nutrients as a result of water pollution and climate change, it begins to create a thick slimy layer on the surface of the water. This layer is colloquially known as sea snot. These algae feast and grow in warm and nutrient-rich water. With the increased water pollution, global warming and deteriorating climatic condition, the overall situation of water bodies across the globe are being affected. Considering sea snot, it also leaves a severe impact on marine life.
