OOCYTES BEGIN IN EARLY SPRING \& REACH MAX SIZE BY JULY. SPAWNING FROM JULY-JAN BUT PEAKS IN AUGUST/SEPT. T.L. UNIQUE IN SIPS IN THAT FEMALES PRODUCE EGGS THAT SPONTANEOUSLY ACTIVATE \& DEVELOP INTO NORMAL LARVAE. MULTIPLE HYPOTHESES ARE CONSIDERED AS EXPLANATIONS OF THIS PHENOM. BUT ONLY FACULTATIVE PARTHENOGENESIS IS SUPPORTED. T.L. IS ONLY SIP REPORTED TO USE THIS REPRO MODE. **TEXT CITES REF TO OTHER STUDIES OF SPAWNING PERIODICITY - MAY WANT TO LIFT.},
