Flabellina affinis (pink flabellina) keeping an eye on me. (f/29, 1/160, ISO-100, 27mm, UCL-165). - Erik
During my dives in Goa,sometimes I came across a Flabellina & thought to myself — what an enormous one! And it turned out… it wasn't just 1. It's at times difficult to tell a singular from a mating pair as this photo.

Mediterranean Cratena. With its colorful shades, it looks like the creation of a talented painter_2023

A close up of a bright red Flabellina (with one of the two orange horns which is shorter, surely bitten by some predator), commonly found in the waters surrounding Goa_2023

Chromodoris quadricolor (pyjama slug). (f/25, 1/160, ISO-100, 23mm, UCL-165 and UCL-67 stacked, the vignetting is caused by the use of a bayonet system putting the wet lenses further from the dome - can be avoided by zooming in). - Erik
Favorinus mirabilis

Swaying nudi
Chromodoris elisabethina

Phidiana militaris. These nudis are covered in appendages named cerata which increase surface area for gas exchange and also to display ingested chemicals or for defence. Sophisticated and surprising nature as always!

Bubble nudi (Doto sp.)
I took this photo one second before this Cratena nudibranch disappeared into the sea grass. I often enjoy waiting for them to emerge from some bush to photograph their big orange eyes!
(Canon100,1/200,f20,iso400)
The u/w world becomes ever more fascinating when you dive slowly, look closely & appreciate the little things. Like this red Flabellina on the wreck off Goa. Here there are many tangled on the wreckage lying a few mt deep.

Go into the light!
It has to be said there is something rather satisfying about a well framed picture of a nudibranch with the rhinophores in sharp focus! This is Chromodoris trimarginata nudibranch_ photographed in Goa_2023
(Canon100,1/250,f20,iso200)
There might be more than one purple nudibranchs in your area, as we see in this picture. When I photograph them, I use two strobes and macro lens 60 or 100 mm. Otherwise everything will just be blue or green!
