Glass minnows are shape shifters. It is possible to see through their translucent bodies.
Shroud Cay, Exuma—I expected that scraping barnacles and grass from the underside of my sailboat would involve hours of necessary but nasty work. Once, after a particularly messy hull cleaning, I came to the surface covered in algae, and my scalp was crawling with biting sea lice.
Today, however, my sealife encounter was ethereal.
As I worked underwater, a sphere of translucent glass minnows surrounded me in a sanctuary they found under the boat. Glass minnows are shape shifters. En masse, they form a defensive cocoon; a cloud of life that changes its appearance like smoke. It’s a fish version of starlings moving together in an underwater murmuration.
I posed no threat, they showed no fear.
It reminded me of the writings of naturalist John Burroughs: The best place to observe nature, he said, is where you are.
As always, sailing is not just about the wind and the sea; the places, the flora, fauna, and people encountered along the way are equally important.

Mom inspired us to follow our dreams. She stands at the rail of our sloop, Free Spirit, as we prepare to sail across the Atlantic together in 1976.
Alvina Cardenas, mother, teacher, artist, and adventurer, died in Key West on February 11, 2025, at age 95. She was loved.
Mom was born in Chicago in 1929, as the country entered the Great Depression. She was the child of modest Lithuanian immigrants, immigrants who made this country great. Her father fought with American infantrymen in the trenches on the Western Front during World War 1.
For the first five years of her life, Mom spoke only Lithuanian. Despite initial resistance from her conservative parents, she became the first member of her family to attend college. Her mother believed that women belonged at home.
Alvie, as she would come to be known, often said that her world only really began when she met the love of her life, the rakishly handsome Bob Cardenas Sr., in front of the bronze lions at the Art Institute of Chicago. They married within months and honeymooned in Cuba in 1951.Dad’s family still owned property on the island. According to family lore, Mom and Dad conceived their first child, Bob Jr., on the beach at Varadero.
After experiencing the warmth of Cuba, they could no longer tolerate the ice and snow of Chicago so they moved to South Florida to begin their lives together and continue building a family. I was born in Ft. Lauderdale in 1955, and our sister, Susan, arrived three years later. Cathy was born in 1964. Mom liked to say that Cathy was the caboose of the family train
Mom tolerated a menagerie in her Florida home, including dogs, cats, birds, snakes, and a troupe of monkeys. The critters kept her busy, but her focus was always on her children. She gave each of her wild, barefoot kids a long leash and somehow kept us reasonably healthy. Mom believed we needed to learn from our mistakes. I learned to never again drink insect poison I found in the work shed. My brother learned not to spill molten lead on his skin when he was making fishing sinkers. Mom was always there for us when we seriously screwed up. She could have found her way to the emergency room with her eyes closed.
Mom’s energy overflowed outside of the household. She became a passionate teacher in several South Florida schools, including one that her children attended (possibly so that she could keep a closer eye on her wayward brood). Mom taught English and Drama. She taught us to use our words, although when we used certain words, our mouths were washed out with soap. I can still taste that bar of Dial soap on the back of my tongue. Discipline was different then.
There was never any shortage of drama as our family matured. One day, Mom and Dad made an announcement. They said, “We’re going to take all you kids out of school and sail around the world.” Each of us responded with a resounding YES!
They sold their possessions and bought a 43-foot sloop, a fixer-upper they named Free Spirit. Dad learned to navigate with a sextant, and Mom made sure that none of us fell into the ocean. We sailed 4,000 miles across the Atlantic.
For years, Mom talked about that trip and how it brought us closer together. She would get dreamy-eyed and say, “Do you remember those night watches near the Azores? The whales were so close to us that I could hear their tails slapping the water.” If only Mom’s Lithuanian parents could have seen her then…
Our family in Horta, Azore Islands, at the great harbor wall where voyagers like Sir Frances Chichester (top right) memorialized their passages.
As sometimes happens when dreams are larger than budgets, Mom and Dad ran out of money. Once Free Spirit made landfall in Spain, they returned to the United States to work while their children scattered into their individual lives.
Our sister, Cathy, died unexpectedly at age 34. Mom and Dad were empty nesters and relocated, finding peace in the mountains of North Carolina. Mom immersed herself in the arts. She built a small studio and installed a pottery kiln. She painted landscapes and portraits, interacting with the talented North Carolina arts community exhibiting in shows and galleries. She was also a grandparent now. One of her great joys was introducing this new generation of Florida kids to mountain country life. She raised goats and cultivated a garden. Mom became a master at crafting wildflower crowns for the little girls.
Mom and Dad returned to Florida because they missed the ocean. They lived in a condominium in Ft. Pierce where they could watch the Atlantic Ocean from the front windows and the Indian River from the back.
In his 70s, Dad joined a cadre of like-minded souls and sailed across the Pacific Ocean from Panama to Melanesia. Mom said, “I’m flying across the ocean this time.” She joined the boat in Vanuatu, and while in Tanna, our parents hiked to the fiery rim of the active volcano, Mount Yasur.
In their later travels, Mom and Dad sailed through the Mediterranean and Caribbean. They walked along the Great Wall of China. They rounded Cape Horn in a cruise ship. And, they were robbed of their passports in St.Petersburg, Russia—and then detained by the Russian government for a week because they didn’t have passports.
Time passed quickly. Mom and Dad aged gracefully. They spent the remainder of their lives in Key West with their children. Two years ago, Dad died. Our parents had been married for 71 years.
Mom, a widow in her mid-90s, relished the role of matriarch to an eclectic band of three children, eight grandchildren, and 12 great-grandchildren. She followed our adventures, cheered our successes, and commiserated with our sorrows.
A few days before Mom’s death, our parish priest came to her bedside and performed the sacrament Anointing of the Sick. Mom’s breathing was labored, and her eyes were closed. She was dying.
Later, with her family beside her, someone quietly said, “We are all here, Mom. We’re here to celebrate you.” Mom couldn’t speak, but she mouthed a question—”So where’s the Champagne?”
Of course, we happened to have a bottle of Chandon on ice. My brother poured a teaspoon of it and lifted it to her lips. Mom smiled her beautiful smile one final time.
Mom is saying goodbye to her 14-year-old son as I rig my sailboat to “run away from home” and sail from Ft. Lauderdale to Key West.

Barnacles nearly drove Charles Darwin crazy while he was researching The Origin of the Species
Barnacles have no heart
Barnacles have the largest relative penis size in the natural world
All true.
Sailors throughout history have despised the lowly barnacle. They grow quickly on the bottom of a boat, causing hydrodynamic drag that can bring even racing sailboats to a near standstill. Several singlehanded sailors in the most recent Golden Globe race around the world had to dive overboard in the chilly Southern Ocean to remove masses of gooseneck barnacles. Racer Jeremy Bagshaw’s boat, Olleanna, could barely move because of an infestation of barnacles. He said, “I didn’t have enough food to go around the world at three knots.” He could have eaten the gooseneck barnacles. They are considered a delicacy in many parts of the world and sell for as much as $100 a pound. One reviewer said they taste like “eating the sea.” Jeremy Bagshaw didn’t want to eat the sea. He just wanted to sail home.
Barnacles have existed for at least 325 million years, which has a lot to do with the fact that they are really good at making baby barnacles. Described as, among other things, the “genitalia of the sea,” barnacles have had to evolve creatively to survive. They are sessile, meaning they are permanently attached to one place and cannot leave their shells to mate. Some barnacles evolved as hermaphrodites. Another way they facilitate genetic transfer between isolated individuals is with extraordinarily long penises. “Barnacles probably have the largest penis-to-body size ratio of the animal kingdom,” according to a report in New Scientist Magazine. “On exposed shores,” the report continues, “it’s better for barnacles to grow shorter, thicker penises” so that the sexual organ is not damaged in rough sea conditions. Regardless of diameter, the penis of a barnacle only lasts for one mating season, and it is then discarded. Fortunately, it will grow a new one the following year.
While the science of a barnacle’s sex life is strange, the medieval bestiary folklore about these creatures is downright bizarre. The 12th-century religious historian, Gerald of Wales, proclaimed that geese (yes, birds) hatched from barnacles attached to driftwood. He wrote: “They hang down by their beaks as if they were a seaweed attached to the timber. I have frequently seen, with my own eyes, more than a thousand of these small bodies of birds, hanging down on the sea-shore from one piece of timber, enclosed in their shells, and already formed.” For some reason, there is a statue honoring Gerald of Wales in Britain’s St Davids Cathedral.
In the 1600s, another disreputable English author and illustrator, John Gerard, perpetuated the myth by claiming to have seen geese emerging from the shells of barnacles. The legend persisted through the 1800s, when, even while the Industrial Revolution was occurring in Britain, some people apparently still believed that live birds emerged from the shells of marine invertebrates.
Famed naturalists Carl Linnaeus and Georges Cuvier were more rational in their observations, but they were convinced that barnacles were mollusks. In 1830, a lesser-known naturalist named William Thompson proved them wrong, and, in a radical reinterpretation of taxonomy, barnacles were reclassified as crustaceans.
Still another Englishman of letters—Charles Darwin, no less—became inspired by barnacles. Inspiration turned into obsession, and Darwin spent eight years trying to understand them. Darwin often worked through the night beneath an oil lamp, dissecting barnacles under the microscope in a room thick with the vapors of preserving spirits.He suffered migraines and intestinal distress, even nightmares. Doctors begged him to stop. Darwin refused. He had begun seeing variations in barnacles no one had ever noticed. His work resulted in a 4-volume monograph on barnacles, living and extinct, and it helped him refine his theory of evolution by natural selection.
Afterward, when asked by an old friend about his passion for barnacles, Darwin responded, “I hate a Barnacle as no man ever did before, not even a Sailor in a slow-sailing ship.”

When we dive underwater, we observe a world inhabited by some of the most fascinating creatures on the planet. Imagine what these creatures experience when a terrestrial biped (us) suddenly appears in their environment. Then, it becomes the observer who is being observed. We are, after all, guests in their house.
There is much science regarding what fish and other sea life see underwater. Fish have spherical lenses in their eyes, which provide clarity, whereas human lenses are relatively flat. Our vision is blurred underwater (unless we wear a dive mask), but fish see everything. Fish also see a visible spectrum that is different from humans. Simply put, fish can see things underwater that humans cannot, even when we wear a mask. Marine reptiles are no exception; a sea turtle’s eye allows them to detect the glow of bioluminescent prey. Some fish, like bonefish, have a membrane over their eyes—like a diver’s mask—that allows them to forage in sand and silt to find food. Sharks may rely on scent and sensory input, but their eyesight is also remarkable. Marine biologists suggest that a shark’s vision may be 10 times better than that of humans in clear water.
That’s all fascinating stuff, but I don’t think about science when I put on a mask and snorkel to free dive on a coral reef. Instead, I am grateful for the privilege of sharing this undersea world, so I tread softly. I enter the water quietly, with minimal gear, and move slowly. I know that everything with eyes underwater watches me to perceive what threat I might pose. I de-escalate. When I minimize my presence, fish become as interested in me as I am with them.
The more opportunities I have to interact with the marine environment, the greater my respect is for a world I once took for granted. All it took was a little bit of eye contact.

The crater of St. Vincent’s La Soufrière, which erupted in 2021
This lovely coastline of Wallibou, in northwest St. Vincent, has suffered greatly in recent years from both man and nature.
Three years ago, the still-active volcano La Soufrière erupted with a devastating blast that displaced 16,000 residents. Smoke and ash covered the island and closed airspace as far away as Barbados.
Then, only several months ago, the sailing catamaran Simplicity was discovered abandoned here with “copious amounts of blood” covering the interior. Police said the American-owned sailboat was hijacked in nearby Grenada by three West Indian assailants and brought to Wallibou. The bodies of Kathy Brandel, 71, and Ralph Hendry, 66, were never found.
Life continues despite the tragedies here. When I arrived in the Chateaubeliar village yesterday, a fisherman in a rowboat dropped off three avocados as a welcoming gift. Ashore, boys fished with handlines for jack mackerel from the rebuilt village pier. And at midnight, I was awakened by the local church’s gospel singing.
I could have avoided this small fishing village along Wallibou’s coastline. Guidebooks recommend caution, and not many sailboats anchor here anymore. Instead, my visit to Chateaubeliar gave me a lesson in the power of perseverance and hope.
