Consigli per l'identificazione

1. 1

   Transparency

   The most striking feature is its almost completely clear body, allowing internal organs to be seen. This distinguishes it from most other freshwater shrimp species.

2. 2

   Rostrum

   Examine the rostrum (the pointed projection between the eyes). Palaemonetes paludosus typically has 5-7 dorsal teeth and 2-3 ventral teeth on its rostrum. The rostrum is relatively long and slender.

3. 3

   Size

   Adults typically reach a total length of 2.5-5 cm (1-2 inches), with females generally being larger than males.

4. 4

   Chelipeds

   Observe the two pairs of chelipeds. The first pair is smaller and more delicate, while the second pair is slightly larger and more robust, though still relatively small compared to other shrimp species.
