Abstract
    Antedon bifida is an annual species. Individuals reproduce in the Spring following their year of birth, and most of them (85%) die in the course of the 6 months after reproduction. A. bifida grows continuously with a growth rate of 3, 3 mm per month (arm length) and a pinnule production rate of 0. 2 pinnule per day. The mean arm length of one-year old individuals is 40 mm (male) and 34 mm (female), and the mean number of pinnules per arm is 70 (male ) and 60 (female) (with the 30 most proximal pinnules being genital). One-year old pre mature males have longer and lighter arms than one-year old premature females. Such differences presumably correspond to a difference in reproductive effort in individuals of both sexes.
