Abstract

The complete larval sequence, megalopa, and early juvenile stages of Pagurus kennerlyi (Stimpson), a member of the capillatus group, are described from laboratory-reared specimens. Development consisted of four zoeal and one megalopal stage. No prezoeal stage was observed. Of the broods obtained from three females, approximately one-third of zoeal stages III and IV from one female exhibited developmental abnormalities, particularly in the second maxilliped. These abnormalities were presumed to be caused by genetic misfortune. Comparisons are made among species of pagurid and diogenid crabs for which juvenile descriptions exist.
