Marty’s photo of the day #4911: Moorish idols are plentiful in the Raja Ampat of Indonesian New Guinea. Photographing them, however, was difficult, because they’d turn away at the last moment, and their mouths were often out of focus or lost in the shadows. It wasn’t until my last snorkel (roughly #30), that I captured […]

Sleeping Sea Krait
While in the Raja Ampat of Indonesian New Guinea, I often explored crevices in the volcanic rock formations along the ocean shore. My usual finds were colorful crabs and lizards, but I also found this sea krait (a venomous snake with a paddle-shaped tail). Sea kraits must leave the water to digest their meals, so […]
Do Redfin Butterflyfish Glow?
Marty’s photo of the day #4910: For yesterday’s photo of the day, I featured a bluespotted grouper that produced the illusion of bioluminescence. Today’s photo is even more extreme. These redfin butterflyfish appeared to be bioluminescent near their pectoral fins. But again, it’s an illusion. Instead, they have fluorescent pigments in their skin that absorb […]
Bluespotted Groupers Change Colors
Marty’s photo of the day #4909: Many of the fish I observed in the Raja Ampat of Indonesian New Guinea appeared to produce their own light. For most of those fish, including this bluespotted grouper, the bioluminescence was an illusion. Bluespotted groupers, however, can change colors for camouflage.
Silky Owl Butterfly
Marty’s photo of the day #4908: This is a silky owl butterfly. Photographed last month in the Raja Ampat of Indonesian New Guinea.
Artsy Parrotfish
I was standing on a dock in the Raja Ampat of Indonesian New Guinea when this beautiful blue parrotfish swam close. With only my Canon land camera in hand, I decided to see what would happen if I shot from above. I think it turned out kind of cool. Artsy even.
Fish Photobomb!
Marty’s photo of the day #4907: It’s a fish photobomb! While snorkeling the Raja Ampat of Indonesian New Guinea last month, I tried hard to get a good horned bannerfish (lower) photo, but they would always turn at the last moment and never seemed to be in crisp focus. Late in the trip, I thought […]
Crab Photography
Marty’s photo of the day #4906: The key to making a dramatic crab photo is to get low and shoot from an interesting angle. Photographed last month in the Raja Ampat of Indonesian New Guinea.
Spinecheek Anemonefish
Marty’s photo of the day #4905: This is a spinecheek anemonefish. Because the Raja Ampat of Indonesian New Guinea supports the greatest number of fish species in the world, Deb and I ended up seeing more species of anemonefish than we knew existed. One of my goals during our snorkels was to shoot a frameable […]
The Bugs of Indonesian New Guinea, Pt 4
I’m concluding my “Bugs of Indonesian New Guinea” day with a weird sight from Deb’s and my rainforest night hike. Is it a spider molting? Is it two spiders fighting? Or two spiders mating? I’m still not sure. But it/they were big. Photographed last month in the Raja Ampat of Indonesian New Guinea.
The Bugs of Indonesian New Guinea, Pt 3
More from my “Bugs of Indonesian New Guinea” day: I’ve seen orb weaver spiders in rainforests across the world. This one is near the top for its eye-catching markings. Photographed last month in the Raja Ampat of Indonesian New Guinea.
The Bugs of Indonesian New Guinea, Pt 2
When Deb and I traveled to all seven continents for my first book, Cool Creatures, Hot Planet: Exploring the Seven Continents, I spent time with a professional photographer/scientist in the Amazon Rainforest. His default name for any bug he didn’t immediately recognize was to call it a “katydid.” With him in mind, I’m continuing my […]
The Bugs of Indonesian New Guinea, Pt 1
Marty’s photo of the day #4904: Today’s theme is “The Bugs of Indonesian New Guinea.” We’ll start with this beautiful dragonfly and move on to the strange and the creepy later in the day. Photographed last month in the Raja Ampat of Indonesian New Guinea.
A Tiny, Tiny Crab
No matter what kind of device you are viewing this crab on, you are seeing it at much larger than real life. Found in a hole of a large volcanic rock at the edge of the ocean, this crab is no larger than the tip of your index finger. Photographed last month in the Raja […]
Checkerboard Wrasse
Marty’s photo of the day #4903: The bright colors of checkerboard wrasses made them stand out—even among all the other colorful fish on the reef. Photographed last month in the Raja Ampat of Indonesian New Guinea.
Overcoming a Fear of Water
If you’ve read my book, Hits, Heathens, and Hippos: Stories from an Agent, Activist, and Adventurer, you know my history of not getting along with water. It goes back to a cigar-smoking childhood swimming teacher I had when I was about ten. His methods included holding the heads of his students under the water. To […]
Invasion of the Crabs
Marty’s photo of the day #4902: Our accommodations at the tiny two-bungalow Raja Ampat Eco Lodge were quite wonderful. However, squeamish people might object to the open design that allowed rainforest visitors inside. During our five-day stay, Deb and I rescued nine land crabs that sneaked into the bathroom through a drainage pipe. Some, like […]
A Snake Story
What would a tropical adventure be without a snake story and photo? One of the reasons Deb and I chose to spend our final five days in Indonesian New Guinea at the tiny Raja Ampat Eco Lodge was because the website promised good herping (searching for reptiles and amphibians). When we spoke with the owner, […]
Raja Ampat Cleaning Station
Marty’s photo of the day #4901: This yellowmargin triggerfish is being cleaned by a variety of wrasses. I watched for several minutes, as the triggerfish turned upside-down and flared its gills to make sure the wrasses cleaned the desired spots. Note the sandperch off to the right side. Photographed in the Raja Ampat region of […]
Swimming With Bottlenose Dolphins
Deb and I got to swim with bottlenose dolphins last month. Getting up early, we took the dinghy from The Katharina to an area where the dolphins were known to hang out. For most of the time, the dolphins were shy. They sank into the murky water and only surfaced when necessary to breathe (photo […]
