Echinometra insularis is a little known and only secondarily studied species of boring sea urchin, which may be due to the remoteness of the habitat islands.
The urchin drills holes in reefs into which it nestles, and reef holes no longer used by urchins are often occupied by other reef species.
The spines of the sea urchin are slender and of a uniform purple color.
As a general rule, bathers should always use bathing shoes in areas with spiny sea urchins and should not touch the hedgehogs without gloves (sting injuries). In addition, the hedgehog is regularly parasitized by small ectoparasitic sea snails (Robillardia cernica E. A. Smith, 1889, synonym: Luetzenia goodingi Rehder, 1980).
