In search of nudibranchs ...

Nudibranchs are the sea cousins of land slugs. Their gills are exposed, naked, hence their name ...

Fresh water and poor visibility

From Tuesday, I start diving in Tioman. First surprise: the water is COLD! ! ! ! I know everything is relative, but here, in this season, we lose almost 4 degrees compared to the very hot waters of the Perhentians.

It's enormous. Spend an hour in water at 30 ° C, okay. But at 25-26 ° C, it's chills and systematic clapping of teeth for the chilly diver that I am. From now on, I will put tank top + T-shirt under my too thin diving suit.

Another surprise, which is not really one, in fact, because I had been warned about it: in July-August, visibility is even worse here, in Tioman, than in the Perhentian Islands and Redang. I realize this from the first explorations, carried out on small wrecks of fishing boats near the coast.

The fascinating sea slugs

So, we are less interested in "big" animals that eventually go off and that anyway we do not see, given the "fog" in the water, to look at the case of small.

Among these very interesting little things that are an inexhaustible subject for those who, like me, do underwater photography (I have my little compact in its waterproof case with me on each of my dives): nudibranchs.

These critters are vague relatives of our land slugs, but much prettier. There are hundreds and hundreds of them, listed in a Bible called 1001 Nudibranchs, whom we hasten to consult when we return to dive shop.

The nudibranchs, there are large and small, long and short, pataux and all purposes, some with a shot "Afro" other covered with pustules. All adorned with new colors and changing. A real festival. 

The above pustular nudibranchs are among the most common species of nudibranchs encountered in Asian waters.
