Species Account:

        Phestilla sp. 2 was photographed and collected by Atsushi Ono from between fragments of dead coral in the waters off Gahi Island, one of a series of islands in the Kerama Islands Group, which are located 30 ~ 40 kilometers west of the Okinawa capitol, Naha. The above image is used with Atsushi's kind permission. Atsushi reports (pers. comm.) seeing only the above single specimen from the Keramas. This animal is very similar to Phestilla sp. 1, collected by Kazuko Matsuda from the waters of Okinawa's main island and it may well be the same species, but until the anatomy is examined the relationship is difficult to determine. Also, the above featured animal would appear to be the same as one depicted in Gosliner, et al (1996, as Phestilla sp., # 625 on p.176).

        Previously, three described Phestilla species have been featured on these pages, all from the waters of Okinawa's main island. These three species are:

  • P. lugubris
  • P. melanobrachia
  • P. minor
