Brown Shrimp feature dorsal grooves on their carapace and last abdomen segment. In contrast to the Brown Shrimp the White Shrimp lacks dorsal grooves on any segment of its body and features much longer antenna. The Brown Shrimp has 2 lower teeth on the rostrum while the Seabob/Brown Mule Shrimp lacks teeth on the underside of its rostrum and its last two pairs of walking legs are noticeably more elongated. Like the Brown Shrimp, Pink Shrimp have dorsal grooves present on head and last carapace segment but are more narrow in width and have a dark spot at third or fourth abdominal segment.
