Our gallery of nudibranchs (well more accurately known as opisthobranchs) from scuba diving expeditions around Indonesia and beyond. Many of these species were found diving in Bali, which is probably one of the richest places on the planet for nudibranch species.
Nudibranchs are probably one of the most photogenic of sea creatures. They come in all shapes, sizes, forms, colours and have the most interesting feeding, behavioural and sexual habits. What makes them even more exciting is that you, me, Joe Bloggs and anyone else out there can go for a dive and find a new species too – now that really is cool hey!
Here you can a variety of unknown, rare, unusual and just very pretty opisthobranchs found on Diving 4 Images trips.
For those really interested in nudibranchs we run a few trips each year just in search of these cool animals and often have some great experts joining.

We often this species on our critter and nudi trips…
Unknown Doto sp. red purple
A very cool critter
A very interesting nudi indeed!
Unknown polycera
We couldn’t even decide what genus this is! Maybe Stiliger or Polybranchia that has been found a few times on filamentous green algae – happy hunting sluggers!
Yes, this species does actually swim. I managed to get two shots at it before it landed and went about it’s day…
Melibe colemani
Thecacera sp. hopefully this will be named in the new book that is coming out soon?
This species of sea slug glows bright red at depth
This always reminds of Salvador Dali for some reason!

Another tiny species that only grows to 6-8mm length
A very rare species, that can be found on a few sites on our critter and nudi trip.
Not so sure on this one
