HERE’S A RULE I FOLLOW ON DIVES: ALWAYS LOOK INSIDE THINGS. You can’t tell what’s you’ll find: Octopuses in holes or old tires, eels in crevices, brittlestars in vase sponges, cleaning gobies in barrel sponges, banded coral shrimps under ledges. Here’s a sharpnose puffer inside a tube sponge in Bonaire. Just hanging out, apparently. There appears to be another little fish, which I didn’t notice at the time, inside the tube at the right.

ON THE REEF, OYSTERS, SCALLOPS, CLAMS AND MUSSELS ARE PRETTY MUCH THE INACTION FIGURES. Mostly, they just sit there. If you come close, they clam up, so to speak, until you go away. Yet, environmentally, economically and, yes, culinarily, they’re big players in the oceans and in our kitchens. Spoiler alert: The bivalve mollusks you’ll see on the reef are unlikely to be the ones seafood lovers salivate over. But, they’re likely to be more

GOOGLE THIS FISH, THE SPOTTED PRAWN GOBY, and most of the posts you’ll find are for the aquarium trade. Amblyeleotris guttata appears to be a popular fish for home saltwater aquariums. Www.fishbase.org carries a listing for it, but it’s largely related to it colors, size and distribution (which is the Western Pacific from the Philippines down to the Great Barrier Reef at Australia. This photo was taken on the GBR). IT’S A SHRIMPGOBY All

SEA ANEMONES ARE PROBABLY BETTER KNOWN FOR THE COMPANY THEY KEEP than for their unassuming, hard-working selves. On Caribbean dives, I rarely pass by one without checking it out for exotic little cleaner shrimps that might be in residence. If there aren’t any, I’m disappointed and move on. In the Pacific, of course, you hardly have to check them out to be aware of their frenetic, constantly on-the-move, high-visibility companions – clowns and other anemonefishes.

IF IT LOOKS LIKE A PIG AND IT WALKS LIKE A PIG AND IT’S UNDERWATER, THEN IT MIGHT BE A…SEA CUCUMBER. Specifically, a member of the genus Scotoplanes. Or, to its multitudinous fans worldwide, a sea pig. Whereas most of us are used to seeing sea cucumbers that actually more or less resemble cucumbers in body shape, Scotoplanes species like S. globosa really do remind people of pigs. Plump, pink and sporting rather porky “legs,”

TO BE SURE, CELEBRATING OCTOPUSES, SQUIDS AND THEIR COUSINS DOESN’T NEED A SPECIAL DATE. But it’s Cephalopod Week, so here are some awesome cephalopod facts, by the numbers: 1. Cephalopods, best known by octopuses and squids, are remarkable for their braininess, and also their brains. Physically, their heads are often larger than their bodies, which perhaps explains why they’re very smart, as well. The term cephalopod is taken from the Greek for, literally, “head-feet.”

SOMETIMES, DURING DIVES, YOU ENCOUNTER THESE THINGS attached to the bottom. They’re squid eggs. Here’s a hint: Don’t Mess With Them! Remember Kirk Douglas battling the giant squid in 20,000 Leagues Under the Sea? It’s could be like that. Maybe. MAKING MORE SQUIDS Squid reproduction is a complex process that involves fertilization following the transfer of a male squid’s sperm – in the form of a single bundle called a spermataphore – into a female’s central

WHETHER WE CATCH THEM OR BUY THEM, the process of having a lobster for dinner begins with lobster eggs – the tasty crustaceans begetting more of the same in the ocean. How lobsters reproduce is an arduous journey that takes as long as 20 months from mating to hatching. During much of that time a female lobster carries her eggs around on her underside, protecting and nourishing them. FIRST STEP TO LOBSTER EGGS: MOLT YOUR SHELL

BANDED CORAL SHRIMPS MAY BE THE FRIENDLIEST CREATURES ON THE REEF. Well, they’re always waving at us. Waving, that is, their super-long white antennae trying to attract passing divers – okay, passing fishes, actually – to come over for a little close-up cleaning. With their prominent tentacles, red-and-white banded bodies and outsized claw limbs, they’re high-profile members of the fish-cleaning profession that’s also inhabited by anemone shrimps, cleaning gobies and other little (often-juvenile) fishes. Found in

IF IT LOOKS LIKE A CRAB AND IT WALKS LIKE A CRAB, THEN IT MIGHT BE A PORCELAIN CRAB, which is a different thing entirely. Which leaves the question: What’s the difference between true crabs and porcelain crabs? They’re both decapods – crustaceans that resemble each other with hard outer shells and 10 appendages, including walking legs extending on their sides and large claws out in front. They both walk sideways, or “crab-like.” But the
