This species is one of the most common shallow water shrimp found in southern Australia. It is most commonly found on muddy soft sediments especially in the shelter of seagrasses. When alive the shrimp is translucent, marked with fine purple-red lines running along the carapace and more sparsely on the abdomen. This species has been commonly referred to as Macrobrachium intermedium in the ecological literature but has since been placed in the genus Palaemon.
