It’s alway good to feel that you might be ahead of the pack – we often hear about Bali and Lombok on one hand, and Komodo and Flores on the other, but what lies in between? JOHN LIDDIARD finds out.

AFTER POINTING OUT

A sizeable nudibranch with six clumps of bubblegum-pink broccoli growing from its back, dive-guide Semuel surfaces from the dive and tells us he has never seen that species before.

Let’s put this into context. Semuel was one of the first Indonesians to train as a dive-guide in Lembeh. He has subsequently worked in all the locations on any diver’s Indonesian bucket-list. He is an expert at finding weird and wonderful macro critters.

You could put him in the middle of the underwater equivalent of an empty concrete car-park, and he would find a loose chip with something small and  interesting underneath it to look at through a macro lens.

And he has just seen a slug that is new to him. Just slugging along on the shallow sand. It was definitely new to the rest of us.

Back ashore, I ask our Canadian host Eric McAskill, a self-confessed obsessive nudi-nut and not diving today. Eric has even published books about nudibranchs. I show him on my camera screen. “Allen’s Ceratosoma!” exclaims Eric. “It’s rare and number 3 on my want-to-see list.”

I ask Eric about numbers 1 and 2, but don’t take notes. Those Latin names go in one ear and out the other.

I look up Allen’s Ceratosoma in Paul Humann’s book and it is “known from Indonesia and Philippines”.

A bit of Googling and I discover that it is camouflaged to hide among soft coral, so sand is not its usual habitat. It is the only species of nudibranch with such long broccoli extensions.
