They can be seen on vertical rock walls in shallow water and on shores and rocky reefs. This stunning creature can be spotted in the Mediterranean Sea and in the northeastern Atlantic Ocean.

This species is a squat and short anemone that has a smooth column. Each beautiful anemone has about 100 tentacles, with each possessing a tiny round blob at the tip. These blobs resemble jewels and can be white-colored or of a shade contrasting with their body. Its tentacles, tentacle tips, and disc are of contrasting colors typically.
