Grows to about 40mm long, and feeds on a variety of sea anemones. It is hard to differentiate in shape and colour from A. alderi, but it has a quite different reproductive behaviour with A. glauca having planktotrophic larval development while A. alderi has direct development, with no planktonic larval stage. See Bernard Picton's message differentiating A. alderi, A. sanguinea and A. glauca.
