In this ventral view of the anterior half of the body, the gnathopods present at the anterior end of pereonite 1 and at the posterior end of pereonite 2 are visible. It has no gills on either of these pereonites.

In this ventral view of the posterior half of the body (head is to right), the flat leaflike gills can be seen on midsections of pereonites 3 and 4 (part of the second gnathopods can be seen at the right on pereonite 2). Ahead of each gill is a small bump which is the vestigial pereopod for that pereonite. Pereonites 5-7 on the left have well-developed pereopods which act as claws to attach the animal to the eelgrass.

skeleton shrimp and young

This view shows pereonites 3 and 4 closer up (the end of pereonite 2 with ghathopod 2 is visible to the right). On each of pereonites 3 and 4 a small, 1-article vestigial pereopod can be seen projecting from near the front of the article and a leaflike gill projects from farther back. Note the large dorsal, forward-directed spine on both pereonite 3 and 4.
