length of the 6th segment; the claw is thin, relatively shorter, and slightly 

 curved. Pereopods VI are much shorter and usually much stronger than 

 pereopods V; the 4th segment is markedly longer than the 5th, which 

 in turn is longer than the 6th segment; however, the length ratios of 

 the segments even in sexually mature individuals are fairly variable and 

 in various studies of specimens the length ratios of the 2nd, 4th, 5th, 

 and 6th segments have varied from 10:8:5.5:2.5 to 10:5.5:5:4; the claw 

 is long, strong, and curved. Pereopods VII are shorter and thin as in 

 pereopods VI, and the length ratios of the segments is highly variable: 

 the 4th segment may be equal to the 6th and each of them 1 .5 times
