You are admiring an outstanding specimen, a Distorsio kurzi (Petuch & Harasewych, 1980) measuring 37.9mm and graded Gem...very unique form & a beautiful coloration is displayed...an amazing specimen. This beauty was collected in tangle nets at 60-80m off Talikud Island Mindanao, Philippines. A member of the obscure Personidae family (formerly w/the Ranellidae family) & an excellent addition for your collection. Thank you for visiting our store this afternoon...great to see you again.
