Recorded distribution in Britain and IrelandRecorded from St. Abbs Harbour, east Scotland; Poole harbour and Plymouth Sound, England; Lough Hyne, Mulroy Bay and the Garvan Isles, Ireland, and Loch Sunart, west Scotland.
HabitatThis is an intertidal species which feeds on sea anemones.
- Two oral tentacles, longer than rhinophores.
- Numerous cerata.
- Tips of the cerata are white or pale in colour, particularly at the anterior end of the body, forming a white ruff around the body. The body is pale cream/fawn in colour.
- Up to 37 mm in length.
Additional informationSpawn forms a convoluted spiral thread containing 200-1200 large eggs. Development is direct, i.e. there is no larval stage. Aeolidiella alderi feeds on a variety of sea anemonies mainly Cereus pedunculatus, Diadumene cincta and Sagartia species (Picton & Morrow, 1994). The body of Aeolidiella alderi is more slender than Aeolidia papillosa (Thompson & Brown, 1984).
