The above pictures were posted on 31 July 2011 and later on these websites as Cratena sp. 04 Genus: Bergh, 1864.
On 30 September 2015 identified Dr. Richard C. Willan this specimen as a variant of Phidiana anulifera (Baba, 1949), thanks! He wrote concerning the rhinophores:"It seems at the number of rings (annuli) on the rhinophores is very variable (from 2-7) in this species and the number can even vary considerably from left to right rhinophore in the same individual."
On 7 October 2015 identified Dr. Richard C. Willan this specimen which was posted on 1 August 2011 on these websites as
Cratena sp. 05 Genus: Bergh, 1864 also as a variant of Phidiana anulifera (Baba, 1949), thanks again! He wrote:"It seems very variable in colour and rhinophoral shape, but all these varieties seem to merge into each other. Overall, there are more similarities in all these photos than differences."
Pretty similar are:
Cratena sp. 02 which differs
- by the backgound colour: translucent with opaque white spots and diffuse orange-tan patches,
- by the cerata, which are mottled translucent whitish and irregularly inflated, and
- by the rhinophores, which are translucent with white spots and have two annulae.
Cratena sp. 03 which differs
- by the backgound colour: translucent with a whitish dorsal region,
- by the cerata, which are translucent orange with purple spots near the base, and have white apices and
- by the rhinophores, which are translucent orange, with bright orange apices, and one annula subapical.
