Felimare tricolor close up. Here I've cropped the shot a bit. Let's say about 30%-40% of the image while still making sure I kept the head with rhinophores quite in focus_August 2023

I usually find this type of Flabellina where there is a hidden current, however it prefers to shelter in creeks. Once found it is pleasant to shot when it opens its cerata upwards as in this photo taken ~15 mt deep_2023

This Flabellina a. with its lively colors seems to say "be careful"!.After feeding on hydroids, they keep intact the stinging nematocysts contained therein & transfer to cerata for defense against predators_July2023

Lately I've enjoyed finding two or more Cratenas close to each other, I wait and, as if they knew I want to photograph them, they approach each other to give me some shots while they are tangled together_August 2023

Photographing from below can be difficult, but it pays off especially if you can find a nudibranch that's on top of a twig like in this photo of a beautiful Flabellina_Scilla_July 2021

Flabellina affinis_July 2023
(Canon 100,1/200,f20,iso200)

Flabellina affinis. Although I photographed hundreds of them, it is always one of my favourites. She was struggling to hold on to her twig without being swept away by current. A pleasant underwater encounter!_July 2023
(Canon100,1/200,f18,i.200).

I almost always use 100 mm focal. Challenging especially at the beginning but surprising for the sharpness, the mass of colors & the gradualness with which it fades into blur, as for this Cratena of Mediterranean sea.

Felimare tricolor are quite common in the Mediterranean Sea but difficult to photograph due to their small size. I like the contrast between strong yellow & electric blue that distinguishes this species of nudis_2023
