Reproduction and development of sabella media a sabellid polychaete with extratubular brooding



Reproduction and development of sabella media a sabellid polychaete with extratubular brooding



Marine Biology 76(3): 301-310



Known reproductive patterns in the polychaete family Sabellidae include: broadcasting of gametes, depositing of benthic egg masses, brooding outside the lip of the tube, and brooding within the tube. There is little information for sabellids in the 3rd category; thus the reproductive biology of S. (= Demonax) media (Bush), one of the few species known to brood its early developmental stages outside the tube, was studied. A total of 32 adults of S. media with egg cocoons were collected from the surfaces of compound ascidians (Aplidium sp. and Didemnum sp.) and from holdfasts of a brown alga (Hedophyllum sessile) at Eagle Cove, San Juan Island, Washington, USA, from June 1981-June 1982, between tidal levels of 0.0 and 0.6 m. The donut-shaped cocoons, each containing over 1000 eggs, are deposited just outside the tube aperture from April-Sept. Larval development takes place within the cocoon through the 3-setiger stage, at which time the larvae emerge [about 8 d (days) after egg deposition]. The newly hatched larvae are demersal and swim near the bottom of the culture dish for 1 d before settlement. Metamorphosis takes nearly a week, and initial formation of the tube is also gradual. The reproductive patterns within the family Sabellidae are discussed, and the adaptive significance of extratubular brooding are considered.
