Nodipecten nodosus (Linnaeus, 1758)

A very interesting specimen from a Florida population which became known to collectors as late as mid 80's, remarkable for its red and white colour and scaly surface and its complete absence of those telltale nodules that originally gave name to the species. By many considered to be a true species of its own and found in the trade under spurious names, especially since the original diver mixed it up with arthricticus which wasn't helpful at all.
