Can be confused only with Uniophora granifera, but differs from that species in having distinctly pointed arms and one row of spines (as opposed to two) along the ambulacral groove on the underside. Juvenile animals generally have blotches of purple on a yellowish background, but these tend to disappear as the animal matures
