Definition
River prawns are freshwater crustaceans belonging to various genera, including *Macrobrachium*. They are typically larger than marine prawns and inhabit rivers, lakes, and streams. These prawns are an important food source in many regions. Some species are commercially farmed. They are like the cowboys of the crustacean world, preferring the wild and untamed freshwater environments. They play a key role in their ecosystem, feeding on detritus and small invertebrates. ποΈ
