Anemones are simple solitary animals lacking a hard skeleton, but supported by internal water pressure. The body is hollow, cylindrical, and attached at the base by a flat adhesive disc. Tentacles ring the mouth and are armed with stinging cells but are generally harmless to humans. Prey captured with the tentacles is stuffed through the mouth into the digestive cavity. Reproduction can be sexual or by simple division of the body.

The striped anemone can be a delicate green, pink or yellowish- brown, sometimes very pale. The column is very smooth, and vertically striped. The striped anemone shoots sticky white defensive threads through the body wall when disturbed. Size is up to 20mm diameter. Fed upon by the Indian nudibranch (Aeolidiella indica).
