It’s All in the Name

In 1995, when we first explored wunderpus territory, which overlies much of the Coral Triangle, the then-undescribed octopus’ fame had spread far and wide. The newly sensational creatures attained much of their acclaim for dancing like dandies across sandy seafloors on eight unimaginably limber arms — an eye-popping feat of acrobatic dexterity well worth traveling halfway around the world to see.

The Argonaut Octopus and the Jellyfish

I DON’T EXPECT TO SEE ANIMALS much larger than my thumbnail while I’m drifting on a night dive in the ocean. So I’m surprised when a translucent skirt of tentacles […]

Cuba’s Golden Fish

IT HAD BEEN A BUSY WEEK for the fish surveyors aboard the Avalon ll, and things were just beginning to wind down. The Reef Environmental Education Foundation (REEF) team of 16 volunteer research divers had recorded population estimates for 246 fish species on 26 reef, seagrass, mangrove, and ironshore sites within the benevolent boundaries of […]

The Peculiar Life of Pearlfish

TO FIND THE FIRST DESCRIPTION OF A LARVAL PEARLFISH in the wild, I had to search back to the early 1980s annals of blackwater diving and Christopher Newbert’s account of drifting 40 feet down a lighted downline tethered to a dinghy bobbing on a night sea somewhere off the Kona, Hawaiʻi, coast. The story appeared […]

Spawning Seas Forever

To the delight of the divers staying at Tawali Resort on the shores of Milne Bay in Papua New Guinea, Anna’s hunch turns out to be right on track.

It Takes Only One Good Fish

OUR RECENT UNDERWATER ADVENTURE began with a fanciful quest to track down an inconspicuous little fish no larger than a nickel. In many ways our mini mission to find the seldom-seen dwarf seahorse (Hippocampus zosterae) seemed more like a weekend lark of carefree youngsters than the stalwart band of seven men and women tugging on wetsuits along the hardpan shoreline of the seldom-explored shallows of Florida Bay in Key Largo, Florida.

The Hamlet Dilemma

SINCE THE LATE 1800S, debate among marine taxonomists has swirled around the species status of the stately little Caribbean sea basses in genus Hypoplectrus, commonly known as hamlets. At the heart of the controversy is the essence of taxonomy: What defines a species?

Japan’s Little Fish with a Big Heart

MANY JAPANESE DIVERS LOVE UNDERSEA CREATURES, particularly the home-grown varieties living in abundance along the country’s craggy volcanic coastlines and offshore islands. They also have an infatuation for the eccentric — the stranger the better.

Hachijō-jima’s Sea of Exquisite Fishes

On our first trip to Hachijō-jima in 2015, we were in the company of friends on a mission to photograph a scientifically undocumented pygmy seahorse the size of a pumpkin seed. Even after a concerted four-day search, the tiny target eluded our efforts until a single seahorse miraculously materialized in the last minutes of the last dive on the last day.
