N2 - Spurilla neapolitana from the Eastern Mediterranean was cultured in a self-sustained, temperature-controlled laboratory culture system, and its life cycle is described. Adults were collected from three field sites situated 120 km apart, along the Israeli Mediterranean coastline, between March 2006 and August 2007. Cultures of the life-cycle stages were raised at 24°C. S. neapolitana deposited white, coiled, spiral egg masses containing zygotes. Veliger larvae hatched 3.0 ± 0.4 days post oviposition. The veliger larvae are obligatory planktotrophs, with a minimal larval phase of 22 days. In the lab, larvae settled and metamorphosed following exposure to metabolites derived from distinct prey sea anemone species. Reproductive maturity was reached 42 ± 5 days post metamorphosis, resulting in a laboratory generation time of 67 days (egg to egg). The average life span of reproductive specimens in this study was 157 ± 13 days post-oviposition and they reached a length of 7-10 cm. During this period, an average adult deposited ca. 40 × 106 zygotes. This species has several characteristics that suggest it will be a useful model for laboratory-oriented research.
