This species seems to be relatively common in shallow waters among rocks, in crevices and occasionally cruising across the algae. As a snorkeler, I see them often in less than 3 metres (10 ft) of water, especially if there are sea anemones in the area. They vary greatly in colouring from a light brownish tint with blueish and/or orange iridescent rings, to a deeper brown to a gorgeous coral/pink/orange colour. Also notible are the visible digestive glands and in a couple of these photos it is possible to see them extending into the head, along the notum, into the cerata and rhinophores. Before seeing a Baeolidia moebii, I had the fortune of finding a young Baeolidia salaamica and I thought they were one and the same, but the salaamica has no visible ramifications of the digestive glands and it has much more obvious whitish-tipped cnidosacs at the tip of its cerata.
