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

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!

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!

That day the visibility was terrible, a meter or less .. at the end of the dive our guide pointed out these two Chromodoris trimarginata ,two white flames that emerge from fog ! Beautiful, colored with their red spots.
