Morphological and ecological studies have been earned out on three populations of the crab Potamon potamios palestinensis inhabiting freshwater springs in the Dead Sea area of Israel. To a certain extent, relative growth patterns followed those already described for other Brachyura. In the males, the chelipeds showed a positive allometry with respect to carapace length, which was probably related to their function in intraâand/or intersexual competition. Righthandedness has been associated with the distribution of scars and mutilations over the body. The wider abdomen is a female sexual character, the allometric growth of which decreases after the puberty moult. Males were on the average bigger than females; it is advantageous for them to grow faster to the size at which they are more likely to copulate successfully. On the contrary, the optimal size of females seems to be conditioned by energetic expenditure for reproduction.
