The biological and behavioral data, while gathered extralimitally, were of major interesl in our projecl work. METHODS Employing scuba diving techniques, we collected spiny lobster sam- ples off San Clemente Island, California (intertidal to 100-fl depths) ;it monthly intervals from Augusl 1964 in January 1967. The animals were kepi alive until their return to the California State Fisheries Laboratory, where they were frozen for later detailed examination. After thawing and segregation by sex. the carapace length was re- corded for each individual (Figure 1). Shell and reproductive con- ditions were designated as follows: 1) old hard shell, (a) ready to he plastered (portion of ventral thorax soft, ready to receive sperm â¢â packet'*^, (b) plastered (sperm "packet" in place), (c) berried eggs attached to pleopodsi; 21 old soft shell (ready to be shed); 'â '< new sofl shell 'just shed i ; 4 i new hard shell. Shell condition was determined by inspecting it for encrusting organisms and testing its rigidity. At this point, an identifying number tag was attached to each tail. The tails were then separated from the thorax with the same quick wringing-pulling motion used in fresh fish markets. After tail length and weight had been recorded, the entire sample was cooked in boiling water for approximately * to 15 min. The tails were then cooled and their respective weights were recorded. Data concerning the physical habitat were limited to water tem- perature, type substrate, and depths of FIGURE 1âDorsal view of a California spiny lobster, with tail separated,
