(kăr′ə-pās′)

Zoology A hard bony or chitinous outer covering, such as the fused dorsal plates of a turtle or the portion of the exoskeleton covering the head and thorax of a crustacean.

the part of the exoskeleton of a CRUSTACEAN that spreads over the head and thorax; in other animals, e.g. the tortoise, the carapace is the dorsal covering of bony plates.

Any possible relationship between smaller (CL < 25 mm) and larger (CL > 25 mm) specimens were determined by comparing the ratios between the means of above measurements and mean carapace length (CL/ABW, CL/POCL, CL/CW, CL/CD, CL/ChL, CL/ChW) of all individuals in each group.
