Marty’s photo of the day #4920: Look closely. Freckled goatfish hunt using their chin barbels to probe the sand for worms, crustaceans, and mollusks, and other prey. Photographed last month in the Raja Ampat region of Indonesian New Guinea.

Christmas Tree Worms on Christmas
Marty’s photo of the day #4919: See the orange fuzzy-looking things? They are Christmas tree worms! There are some blue and green ones too. Also in this photo are sea squirts and coral. Photographed last month in the Raja Ampat region of Indonesian New Guinea.
Distracted By Fish
I didn’t get a bluegirdled angelfish photo that was good enough to print or make my photo of the day, but I’m sharing it anyway, because I’m doing the final-final-final-final read-through of my latest novel, The Silver Squad Rides Again, and am easily distracted. Photographed last month in the Raja Ampat region of Indonesian New […]
Crab Migration
Marty’s photo of the day #4918: While Deb and I were returning from a night hike on the island of Waisai, we noticed dozens of crabs on the wall of a shed and on the path in front of us. As we learned later, they were part of an annual nighttime migration to the ocean […]
Unbelievable Colors
Marty’s photo of the day #4917: I remember the first time I tried snorkeling. It was early in Deb’s and my marriage, and it didn’t go well. One thing I remember from my brief time in the water was all the incredible colors, brighter than I’d ever seen before. Now that I’m comfortable snorkeling, I […]
Here Come the Bottlenose Dolphins!
Here come the bottlenose dolphins! Deb and I swam 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 […]
The Foxface Rabbitfish Challenge
Marty’s photo of the day #4916: I love the challenge of wildlife photography, whether it is on land or in the water. Even among all the colorful and unusual fish on the reefs of the Raja Ampat, foxface rabbitfish stand out. They weren’t a common sight, and when I saw them, they were frustrating to […]
Heading to the Dolphins
Heading out at sunrise to swim with bottlenose dolphins. Photographed last month in the Raja Ampat of Indonesian New Guinea.
Pacific Bluetail Skink
Marty’s photo of the day #4915: This is a Pacific bluetail skink. Photographed last month in the Raja Ampat of Indonesian New Guinea.
An Apology to My International Shipmates
Last month, when Deb and I sailed on the Katharina in Indonesian New Guinea, the first thing I did was apologize to my international shipmates for Donald Trump and his bigoted, vindictive, hateful behavior. One other American was on the boat with us. She (a professor from Columbia University) arrived a little later than we […]
Just Like in the Book
Marty’s photo of the day #4914: This is an orange anemonefish (sometimes called an orange skunk anemonefish) with a Merten’s anemone. If you have access to “Reef Fish Identification: Tropical Pacific” look it up. The photo in that book is virtually identical to my photo taken last month in the Raja Ampat of Indonesian New […]
Bat Island
Many of the smaller islands in the Raja Ampat of Indonesian New Guinea are “bat islands.” I shot this series of photos as we approached one of those islands. It was teaming with flying foxes. Since we were returning from a stop at a waterfall, I only had my underwater camera with me. I would […]
Blackpatch Triggerfish
Marty’s photo of the day #4913: This is a blackpatch triggerfish. Photographed last month in the Raja Ampat of Indonesian New Guinea.
The Badass Chickens of Indonesian New Guinea
Photographing the Moorish Idol
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.
