This species is a member of the 'broken-back shrimp' because the tail is sharply flexed and is bent upwards (McClory and Gotthardt 2005). These authors provide the following description for this species: "A small, slender-bodied marine shrimp. Color usually bright green, but may also be brown or reddish. Shell is thin and smooth-surfaced, walking legs (pereopods) are typically transparent. Third segment of the abdomen protrudes dorsally at its posterior margin into a distinct hump. The well-developed rostrum (head carapace) slopes upward to a three-pointed tip and carries 2-5 spines along its upper edge and 1-5 spines below (O’Clair and O’Clair 1998)."
