FISHERY BULLETIN: VOL. 71, NO. 1 



Anomura studied but not necessarily reduced 

 time spent in the plankton. This suggests that 

 intermolt growth might permit larvae of these 

 species to develop to metamorphosis under a va- 

 riety of conditions without passing through a 

 large number of molts. This mechanism might 

 thus be of survival value in reducing larval loss 

 at molt by effectively decreasing the number of 

 molts required under various conditions to reach 

 the juvenile form. 



As more larval histories are studied, it may 

 be found that intermolt growth occurs in Ano- 

 mura other than the Porcellanidae. If the func- 

 tion and value of intermolt growth has been cor- 

 rectly interpreted here, this form of variability 

 might be expected among species with low num- 

 bers of larval molts required to attain the sub- 

 adult. Only careful studies of more life histories 

 can reveal the possible relationship of intermolt 

 growth and variable stage numbers.
