Additional information: The first pair of walking legs are elongated and very thin, ending in delicate claws which are used as feeding appendages. The second pair of walking legs are much larger and powerful, especially in males. The movable claws of the second pair of walking legs are distinctively covered in dense bristles that give it a velvety appearance. The color of the claws in males varies according to their social dominance.

Note: The larval stage of the animal depends on brackish water. Once the individual shrimp has grown beyond the planktonic stage and becomes a juvenile, it will live entirely in freshwater, hence they are considered as freshwater species.
