These photos were all taken in the Lembeh Straight (North Sulawesi) and Raja Ampat (off the NW tip of Papua) areas of Indonesia.  Lembeh, with its black sandy bottom, has the largest concentration of strange little critters anywhere.  Raja Ampat is believed to contain the most prolific marine biodiversity (both fish and coral species) on the entire planet.  All photos were taken with a Canon 1Ds Mark II camera (16.7 megapixels) in a Seacam housing with dual Inon Z220 strobes.

Soft coral & jungle above

Masked angelfish (12 inches long)

Red soft coral with one black crinoid

Pink anemonefish (2-3 inches long) above purple anemone

Blue-ringed octopus (2 inches): only the size of a plum, this is one of the most poisonous creatures in the ocean (if he bites you, you're dead within 15 minutes). In other words, look but don't touch!

Tiny banded pipefish (2 inches long) on brown coral

Six-banded angelfish (14 inches long) among soft corals

Coral trout (12 inches long) beneath sea fan with glass-fish

Nadia photographing giant clam (2ft wide by 5 ft)

Mandarinfish (2 inches long) mating at dusk at Lembeh. These "twighlight quickies" involve pairs rising 6-12 inches above the rubble and--about 3 seconds later (even faster than most humans!)--completing the "act" by releasing their respective fluids in a puff and bolting back into the reef.

Mandarinfish mating (again!): The larger female (rear)found a healthy young maile, so they mated several times. Catching them "in the act" (and in focus!) is an exercise in frustration, so getting two shots of this pair was one of the highlights of the trip for me.

Tiny crab (1/4 in. across) on sea cucumber

Fire urchin - well named for the intense pain caused if/when its spines inject fiery toxins upon contact (my knee "contacted" about 80 spines)...

Mantis shrimp (4 in. long)

Crinoid with trees and sky above: this was one of several photos taken at "The Passage" in shallow water looking up through the surface at the trees above.

Coconut octopus (2 inches) hiding in shell: too small to use a coconut, this little guy is practicing using two shells as his hiding place.

Mimic octopus (8 inches long)

Solar-powered nudibranch (6 inches long): If you look closely, you can see the "branches" inside, upon which this little guy grows algae to live on.

Pipefish (3 inches long) are related to seahorses, and have wonderfully "intelligent" looking eyes.

Sweetlip snappers (10-12 in.)

Emperor angelfish (12 in.)

Bobbitt worm (and yes, it is named after the fellow whose wife chopped off his you-know-what!)

Archer fish (4 inches) with his reflection in surface: these fish swim along the surface beneath overhanging trees. They spot insects on the tree branches above and "spit" water to knock the insects into the water so they can eat them.

Bumphead parrotfish (2-4 ft long): This is the closest I've ever gotten to one of these schools ("gangs" seems more appropriate). Parrotfish eat hard corals, digest the organic material, and the "outcome" is sand. In fact, much of the world's sand is believed to be parrotfish poop!

Bumphead parrotfish feeding: we counted over thirty of these 100+lb monsters, which raised quite a cloud (reminded me of buffalo) when they stopped to feed like this. Note that the coral already looks dead; this appeared to be one of the places where lazy fisherman had used dynamite, a practice that devastates the reef.

False clownfish (1-2 in.) in fully closed anemone

Decorator crab (4 in.) with anemones "planted" on his shell

Orangutan crab (1 in. across) in hammer coral

Crinoid (5 in. across) swimming up: Crinoids are usually seen perched atop corals so they can feed (with their feathery arms) on passing plankton. Occasionally, however, one can be seen swimming to reach higher ground.

Hairy frogfish (5 in.) "fishing" by wiggling his lure -- if a little fish comes to investigate, he will be eaten in one quick gulp!

Shrimp goby with his shrimp buddy: this is a symbiotic relationship, in which the goby stands watch, while the shrimp excavates and maintains the hole they both live in.
