Doto pinnatifida
(Montagu, 1804)
Kirstie Harris Found this chap on a site in Pembrokeshire over the weekend. Can anyone tell me what it is? Thanks.
João Pedro Silva Really need some more detail, but I think there are only 3 possibilities * in your area: Doto fragilis, Doto pinnatifida and Lomanotus marmoratus.
My guess is D. pinnatifida.
* feeding on Nemertesia antennina
Kirstie Harris Thanks! My husband took some photos too, so he might have a better one. If he has, I'll ask him to post it.
Terry Griffiths I would go for D. pinnatifida
Klas Malmberg Aquatilis D. pinnatifida - black tipped tubercles both on cerata and on the sides of the body
João Pedro Silva After downloading and enhancing the image, no doubt on my first guess.
João Pedro Silva Doto are really hard to spot and sometimes even harder to identify. It's very important to also document the hydroid they're on. This Doto pinnatifida feeds exclusively on Nemertesia antennina. It cand be mistaken for Doto tuberculata but the later feeds on Sertularella gayi.
Bjørnar Nygård João Pedro Silva, the nudibranch in question might have been on the hydroid Kirchenpaueria pinnata, but I'm not sure.
João Pedro SilvaDoto dunnei, I think.
Bjørnar Nygård Ok, thanks. I've collected the specimen and will send it to Jussi Evertsen.
Carissa Shipman So kool! Completely new!
Bernard Picton The shape of the tubercles is different to D. dunnei in my opinion. Trouble is the hydroid taxonomy isn't robust either plus some hydroids certainly support more than one species of Doto. Nemertesia species are particularly interesting, with Doto fragilis eating two species of Nemertesia, Doto pinnatifida one of these and Doto cuspidata the other.
