Species Account:

        Nembrotha sp. 1 is considered to be very rare on Okinawa as the above feature animal is the only one I've seen here. It was collected during an mid-morning SCUBA excursion from an area of mixed rock and coral rubble at the reef forefront. The animal was found with the posterior end of the notum damaged and I couldn't get an accurate crawling length; it had a total length of at least 38mm. I've added a second image of the same animal which shows a different view with a bit more detail.

        Nembrotha sp. 1 is one of several Nembrotha species known from Okinawa. Previously I've featured several members of the genus on these pages and as of the current date, there are several described and undescribed species reported from Okinawan waters. These featured animals are as follows:

  • N. guttata
  • N. kubaryana
  • N. lineolata
  • N. livingstonei
  • N. milleri
  • N. species 1 (the above featured animal)
