Fuzzy Nautilus, Allonautilus scrobiculatus

Though closely resembling its better-known cousin the Pearly Nautilus, this species differs by having visible early coils and a thick, velvet-like protective coating (the periostracum) on the living shell. When the coating is removed, as here, a pattern is revealed that is similar to that of other Nautilus species. It is native to the deep seas surrounding New Guinea, and is comparatively rare.
