Favorinus blianus

Lemche & Thompson, 1974

Tim Nicholson I have this as favorinus blianus, the only one I've ever seen on the Isle of Man. Can anyone confirm?

Bernard Picton Yes Tim, it's the only one in the area with those three rings on the rhinophores.

Terry Griffiths Hi all Sorry not a great photograph as taken with a wide angle lens and cropped heavily ,i would say it's Favorinus blianus but a colour morph but then again as i live in the S West i could get anything here.

Erling Svensen This nudi at Gulen with eggs under a rock. I have problems.... Please give me some help...

Kjetil Breivik Johnson Nice little fellow :-)

Jim Anderson From the shape of the rhinophores and the white on the cerata and oral tentacles I'd say this is Favorinus blianus - the colour in the cerata comes from the eggs it has been eating I think.

Sarah Bowen Yes, I see what you mean - the colour had me confused too, but if you look carefully there's a kind of 'ribbed' effect to the rhinophores which is characteristic of this species. Great shot!

Bernard Picton Those eggs look like Berghia norvegica, could be a new food for F. blianus.

Erling Svensen This was down the track and just below all the F. browni nudies to the right, Bernard.

Bernard Picton I think it is quite unusual for nudibranchs to lay their eggs beneath rocks and shells, and the spiral looks right for Berghia. We should measure the egg size to see if it matches the size range for species with direct development; that is where the eggs hatch directly into small slugs with no swimming stage. It is the most uncommon type of development in northern waters.

Christian Skauge Favorinus blianus on Berghia eggs in my opinion too :-)
