Yes, in their own unique way, shrimp play a role in cleaning the ocean. They're often referred to as the "vacuum cleaners" of the sea. This nickname comes from their scavenging habits. Shrimp feed on dead plants and animals, along with other detritus, effectively recycling nutrients back into the ecosystem. While they don't clean the ocean in the way a filter might, their feeding habits help maintain the health and balance of their habitats.
