Plate 22. Third-Stage Lobster. 



Figure 31. Right cheliped from behind, M=27. The exopodite is still 

 strongly functional, but the claw, or chela, has further developed and the whole 

 endopodite is stronger. In this stage is noticed especially the beginning of that 

 torsion of the claw which, by the fourth stage, brings the dactyl to open toward 

 the inside in a nearly horizontal plane.
