Dear Dr.Rudman,
Hydatina zonata is common in Hachijo, but it is a seasonal animal, usually found between June and October. I temporarily dug them from the sand and moved them to the rock so I could photograph them.
Date: 1 July, 2001
Place: Sokodo, Hachijo Island, Japan
Depth: 8m
Size: 50mm & 30mm
Best Regards,

Thanks for these beautiful photographs. Do you ever find Hydatina physis or Hydatina cinctoria (= Hydatina albocincta) with H. zonata? Hydatina cinctoria is the one with broad brown spiral bands on the shell. I sometimes wonder whether these three species are just colour forms of one species
Best wishes,
Bill Rudman.
