Description:

In gammarid amphipods the last three abdominal legs are uropods. This view shows a dorsal view of uropods 1 (lowest) to 3 on the left side of the animal. Above the base of uropod 3 the telson can be seen, then uropod 3 on the right side of the animal is visible at the very top. Uropods 1 and 2 have two similar rami composed of flattened blades with setae along the edges. Uropod 3 has a paddlelike inner ramus (seen on edge on the left, close uropod and from the flat side on the right, far uropod). The outer ramus of uropod 3 is less flattened and has two apical teeth, as seen below.
