Okenia rhinorma from Hachijo Is., Japan

February 9, 2008
From: Bill Rudman

While searching throught the unidentified seaslugs on the forum for another 'unidentified' nudibranch I found a message from 2001 concerning an Okenia from Japan by Nishina Masayoshi [message  #4736].

It is clearly the species I have recently described from east Africa and the Red Sea as Okenia rhinorma and so greatly increases the known distribution from the western Indian Ocean to the western Pacific. The enormous rhinophores are very distinctive.
