Summary
DescriptionBlue dragon-glaucus atlanticus (8599051974).jpg |
English: Also known as Sea Swallow, Blue Glaucus, Blue Sea Slug, Blue Ocean Slug and Lizard Nudibranch.
Washed ashore at Bronte Beach, Sydney, NSW. Diet: Bluebottle (physalia physalis) Speciality: Stores stinging nematocysts from the bluebottle within its own tissues, which is additional protection from predation Discovered: 1777, Forster.Français : Le Glaucus atlanticus ( aussi nommé glaucus atlantique ou glauque, ou encore "lézard" nudibranche) est une limace de mer, aux couleurs dans les tons de blanc, gris perle et bleu, qui s'alimente principalement d'hydrozoaires, tels la physalis ( vessie de mer), dont elle stocke les nématocystes, ce qui lui confère un pouvoir urticant la protégeant des prédateurs. On doit à Georg Forster sa première description scientifique en 1777. Photo d'un spécimen échoué sur la plage de Bronte, Sydney, Nouvelle-Galles du Sud, Australie. |
