Shrimp are omnivorous creatures that feed on a variety of foods, including algae, plankton, and detritus. Some species may also consume small fish, mollusks, and even decaying organic matter. Their diet can vary based on their habitat and availability of food sources.
As for their lifespan, it generally ranges from 1 to 7 years, depending on the species. For example, common species like the Pacific white shrimp can live about 2 to 3 years, while some larger species might have longer lifespans. Environmental factors, such as water quality and predation, also play a significant role in their longevity.
