With the poor vis, everything seems brown. You can't imagine that the right lighting allows to discover otherwise invisible details. Like in this close-up of a hermit crab photographed a few mt deep in the sea of Goa_2023
(Canon100, 1/200,f14,i.100)

Marine flatworms are often very little creatures, easy to spot when diving and, if you have a good macro lens, you can well focus on them as I tried in this photo taken in Goa, India_2023

Eye detail of a flathead fish found hidden under the sand during a diving in Goa. Once identified, it can be photographed without problems thanks to its peaceful nature & the belief that it will not be discovered!_2023

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.

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
(Canon100, 1/200,f20,iso200)

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!
(Canon100,1/250,f20, iso200)

A blenny looks out of its burrow suspiciously. Note the fleshy branching appendages (named cirri) found above their eyes and nostrils. The biological role of cirri remains unclear but make them very nice!

This is small Hermit crab having very pretty colors on its body. It lives between the surface up to 70 meters deep. Its shell is a matter of survival, to protect its soft abdomen. I took this photo in the sea of Goa_2023
(Canon100,1/200,f20,iso200)

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.
(Canon100,1/250,f25,i.250)

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!

Chromodoris naiki with characteristic pale light-blue band at the edge of the notum and scattered large spots of dark purple in the dorsum. Very photogenic nudi! Shot taken at the wreck of Goa, in poor visibility_2023
