I took this photo two years ago at Hitotsuishi point , Owase, Japan. Although, I checked the name of them on a lot of books or websites, I couldn’t have got it. And I gave up at that time. Last weekend, When I was selecting my photos, I find out photos of this anemones. this time, I asked FB page “ID Please?”. Then, only in one day, the answer was coming Thank you Joe Fish, and “ID please?”. I could to know the name of this beautiful anemone, and the fact they are living in the deep sea also.
According to Graellsia, 60(2): 143-154 (2004), Ring sea anemones seem to be more common at depths between 85 and 1500 m. Five different species of ring sea anemones are recognized, one described by Hiles (1899) as Peronanthus verrucellae, and the others named by us provisionally as Peronanthus sp1, sp2, sp3 & sp4. Ring anemones on this photo is Peronanthus sp3. It is said although sp3 lives in shallow water than the other, still, sp3 is found at 30-50 m. I took this photo only -18m. Wow, Owase is lucky place for taking underwater photography.
