This view shows the same individual from the dorsal aspect.
-
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.
-
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.
-
In this lateral view of the head and antennae 2, the long setae on antennae 2 can be seen. The next to last article of antenna 2 is about 6x as long as wide and has setae at least 2x as long as the article is wide. Notice also the large, single dorsal spine on the head and the small first gnathopods at the anterior end of pereonite 1. The large first antennae are extending upward out of the picture.
-
This dorsal view of the head shows more clearly the first and second antennae.

This closeup shows pereonites 5-7 with their appendages, pereopods 5-7. Pereopods 5-7 arise from the posterior end of their segment (pereonite) and are used for gripping the substrate such as this eelgrass blade. The left pereopod 7 is missing.
-
The propodus of gnathopod 2 is less than 2/3 as wide as it is long. Note also the gill on the segment behind.
-
This ventral view shows there is no spine between the large gnathopods 2 and shows the location of the gills.
-
This view of the head (animal is looking to the left) shows the very large second antennae to the left, then the head with sessile eyes and prominent, forward-directed head spine. Below the head can be seen the first gnathopods which are on the anterior end of the first thoracic segment (pereonite), which extends out of view to the right.

Caprella angusta from eelgrass in Padilla Bay. Total length about 4 cm. One of the ventral flaplike gills is visible posterior to the large grasping gnathopods 2, right at the end of the eelgrass. (Photo by: Dave Cowles, July 2008)
