Material examined.MBC-A 022263; MBC-A 022657; MBC-A023311; MBC-A077879; MBC-A077878; MBC- A077880; MBC-A077881; MBC-A077876; MBC-A077877; SAMC- 22262, Identification.Test strongly elongated, rarely somewhat circular; spines stout, with white basal flange (milled ring). Distinguished by color, cleaned test white, with faint light purple tint; spines vary in color, from white to brown, sometimes greenish or purplish, often tips and milled ring white.
Global maximum size.Maximum test diameter 90 mm. Globaldistribution. Suezto Eastcoast region of South Africa, from Japanto Australia, and from Hawaiito South Sea Islands; from littoral to 30 m( Schultz 2010).
Remarks.Inhabits holes and tunnels amongst coral blocks, known to be a rock borer ( Mortensen 1943; Asgaard & Bromley 2008)). Feeds on algae and encrusting organisms, especially sponges ( Mortensen 1943; Schultz 2010). Maher (2011)indicates that there is no genetic divergence amongst the color morphs in E. mathaeipopulations and suggests variation may be attributed to environmental parameters. However, the observed intraspecific variation may suggest a slow speciation process ( Rahman & Uehara 2004).
