There are many unsung heroes on our reefs, one of my favourites is the long nose hawkfish in Bunaken, and its not often you manage to get two of them in a frame. Of course everyone likes to see the big stuff, turtles, sharks, rays and other big pelagics; and you have the other end of the spectrum where divers love the hunt looking for smaller and smaller shrimps and other critters.

However one of the things that makes Sulawesi is the sheer number of species; the biodiversity of fish and coral is immense: one of the highest in the world. Often whilst diving I come across fish species that I do not remember seeing before, but you would be hard put to remember everything you can see here. Gobies, blennies, basslets, lion fish, butterfly fish, angel fish, trevally, triggerfish they all have so many representative species.

The coral cover too, is so dense and overlaid it is often very hard to see what is living amongst it. This week we have a couple of marine scientists, who typically study coral in the barrier reef, over for a weeks holiday. They are blown away by what we tend to take for granted here. Which is great makes for very easy guiding.

We are also joined this week by Scott who has learned to dive in Lembeh and will now continue his Divemaster course with us, good luck Scott. I hope you can appreciate the diving just now as you are being spoiled; its not everywhere this good.
