Actinoporus elegans, commonly known as the elegant anemone or the brown-striped anemone, is a species of sea anemone in the family Aurelianidae. This species may exhibit a high degree of colour variability, from blue to white to nearly transparent. The column is smooth and textured near the top and bottom, growing to a maximum of 15 centimetres (5.9 in) in height and with a diameter of about 5 centimetres (2.0 in). The base, about the same diameter as the column, is deeply buried in the substratum. The disc is flat and also about the same diameter as the column. Although the surface of the disc is hidden by tentacles at the fringes, there is a small exposed area at the centre where the distance between them is greater. Both the base and column are mostly white with some clear areas. Near the disc, the ridges may be a translucent brown colour. This translucency is due to the thinness of the base and column walls. The tentacles are short and wart-like, appearing almost non-existent, giving the surface of the disc a "finely beaded" appearance.
