Abstract
A population of Capitella capitata (Fabricius) was sampled from January, 1973 to February, 1974. Size of the worms was measured and sexual maturity determined. There is an extensive breeding season, spawning occurring asynchronously throughout the year. Females containing ripe oocytes were almost always present, but most females at any one time contained immature oocytes. A high percentage of males contained active sperm. Oocytes are not released into the coelomic fluid until almost fully developed, and all are released at a single spawning. A large number of eggs are produced at each spawning and there is some evidence to suggest that larval development may be completely benthonic. Gametes first develop in 7 to 8 month old worms and take about 4 months to complete development. Analyses of the female population structure suggests that there are 3 breeding classes. The growth rate is estimated at 30 mm per year, and few worms are believed to survive longer than 2 years.
