First In Situ Observation of Sperm Release in <i>Corynactis carnea</i> (Anthozoa: Corallimorpharia) from Patagonia, Argentina
Jewel sea anemones constitute a relatively small group of solitary cnidarians, a sister group of scleractinian corals. In the southwest Atlantic Ocean off Argentina, two species of jewel sea anemones have been found: <i>Corynactis carnea</i> and <i>Corallimorphus rigidus</i>....

| description | Jewel sea anemones constitute a relatively small group of solitary cnidarians, a sister group of scleractinian corals. In the southwest Atlantic Ocean off Argentina, two species of jewel sea anemones have been found: <i>Corynactis carnea</i> and <i>Corallimorphus rigidus</i>. <i>Corynactis carnea</i> is a common and abundant species in shallow water of northern Atlantic Patagonia, but reproductive data on this species is scarce; the species is known to reproduce asexually. During a SCUBA diving survey in an Atlantic rocky reefs (20 m depth) in Patagonia, we observed for the first time specimens of <i>C. carnea</i> releasing sperm, eight days after the full moon and during the summer season while spawning has been previously observed in at least three species of <i>Corynactis</i>, but all were recorded as occurring in winter. |
