We saw numerous lionfish, silvertip, whitetip, black tip and nurse reef sharks. One hammerhead, one ray shark, and one lepoard shark One giant queensland grouper - got him on video (divemaster said he must weigh about 400 Kilos) he was wider than I am tall, and much longer, and was lazily swimming around in about 40 feet of water on top of Tijou reef. We saw him several times on each of the 2 dives we did there. We also saw giant schools of large sweetlips, large schools of chevron barracuda, including a long line of them waiting their turn at a cleaning station. Many large turtles, many different kinds of large groupers, including a brilliant black and yellow one (don't know the name). Many lage schools of batfish. Lots of untouched pristine hard and soft corals of all kinds. Enourmous angles, (much, much bigger than in Hawaii or the carribean) parrotfish and endless varieties of damsels in schools so large you couldn't see through them, they filled the water around you. Some bumphead parrots over 3 feet long (boy are they weird looking). Giant clams on most dives - they really are giant. One of the things that made the reef so beautiful was the density and variety of filter feeders, I have been studying my pics, and even now I am seeing new things in them, there was just too much to see to take it all in (dozens of different things every square foot of reef).
