Remark |
: |
As in the other families belonging to the infraorder Caridea, the pleura of the second abdominal segment overlap those of the first and third segments, and the third pair of pereiopods lacks pincers. The body is usually glabrous. Rostrum well developed with dorsal and ventral teeth in the commercially interesting species. Legs without exopods. First pair of pereiopods ending in small pincers; those of second pair more developed, ending in strong, robust pincers, their carpus simple (undivided) (Ref. 104052). To about 34 cm (Ref. 94508). This family includes marine as well as brackish-water and freshwater species. Of the 2 subfamilies Pontoniinae and Palaemoninae, only the latter includes species of commercial interest. Up to now, only few West African marine species are of some interest to fisheries. Several fresh and brackish water species are of local interest (Ref. 104052). |
