The idea of swimming with whale sharks made me nervous. I wanted to so badly but the memory of my bizarre reaction to a spinner dolphin in Costa Rica a few years ago haunted me, and I was afraid I’d humiliate myself, yet again.
My reaction had been utterly irrational. I was in the water near Peurto Jiménez when I saw a dolphin swim toward me, its dorsal fin slicing through the water like a……. SHARK!
Instinctively, my body seized control. Adrenaline coursed through me
I felt like an ass. Intellectually I knew it wasn’t a shark but I hadn’t been able to stop myself. (This is what I get for watching reruns of Jaws.) Would I respond the same way with a whale shark? Let’s face it, it looks more like a great white than a dolphin. The logical me said of course not but the insecure me said… maybe.
My swim was scheduled for the last full day of my week-long adventure with UnCruise in Mexico, sailing up and down the coast of the Sea of Cortez, also known as the Gulf of California.
The trip had been filled with beautiful sun-drenched days, spectacular sunsets, hikes, snorkeling, kayaking, a lot of good food, and new friends. Our last excursion was the crescendo to an already unforgettable trip: A morning in the Bay of La Paz communing with the world’s largest fish.
First: Some Whale Shark Facts
Are whale sharks dangerous?
what their name and size might imply, whale sharks are docile and barely seem
to notice humans swimming beside them. It’s weird really, it was as if we
Is a whale shark a whale or a shark?
Whale sharks are huge, hence the whale reference, but they are sharks. Unlike whales, they’re fish
What do they look like?
They have distinctive white dots and checkerboard markings which make them easy to find beneath the waves. Like the fluke of a whale’s tail or the stripes on a zebra, each pattern is unique. Researchers use advanced star-mapping technology to find members of the population and track their migration patterns. Some whale sharks have been known to travel thousands of miles to different feeding grounds.
How big is a whale shark?
According to Ocean.org the largest whale shark ever recorded was a 65-foot-long female—twenty feet longer than the average school bus. Average size is 16 to 32 feet.
How much do whale sharks weigh?
It’s hard to imagine, but whale sharks can weigh 10 tons. That’s more than a full grown elephant.
What do whale sharks eat?
Whale sharks are filter feeders, surviving on the smallest creatures: plankton, squid, tiny plants, and other nibbles floating in the water. They swim slowly, mouths agape while 20 distinct filtering pods (mesh-like organs) strain the nutrients.
Sometimes they float perpendicular to the surface—a position described as “going vertical”—sucking in vast amounts of water and creating what looks like from above a small whirlpool. Their gills flush out the excess (nearly 1,600 gallons an hour).
Where do you find whale sharks?
Though endangered, you’ll find whale sharks all over the world in warm, tropical waters except the Mediterranean. They’ve been seen off Australia, Africa, Philippines, Maldives, Mexico, and Thailand, among other locations. They’ve been known to migrate thousands of miles in search of food.
What is a whale shark’s lifespan?
Researchers estimate that whale sharks may live 100 years or more. It’s not surprising really,

La Paz, Mexico
Paz is the capital of the Mexican state of Big Sur California, a bustling,
quaint coastal town 90 miles north of Cabo San Lucas on the eastern side of the
peninsula. (I didn’t have time to explore the city, but I can vouch for the
deliciousness of the ice-cream at La Fuente on Paseo Alvaro Obregon across the
street from where our ship, the Safari Endeavor, docked.)
The season for whale sharks in La Paz is between October and March when juveniles migrate to the bay for its temperate waters and abundance of food.
Because the whale sharks are endangered, large sections of the area are protected and monitored. The number of boats
Whale sharks skim the surface of the water to feed, making them prime targets for boats and captains must constantly be on the lookout. In addition, the approved region is designated by GPS coordinates. At one time, buoys delineated the protected areas, but they quickly became hazards, tangling the easy-going giants in their anchor lines and thus removed.
Swimming with Whale Sharks: What it
was like in La Paz
Passengers aboard the UnCruise interested in seeing the whale sharks were split into small groups and scheduled throughout the day. I and five other guests were the first to go in the morning
Fun Baha, a local UnCruise partner, picked us up in the Carolina, a small passenger boat and our home base for the excursion. Sarah, our ship’s very energetic, husky-voiced naturalist, was our lead.
The journey to the protected area took about 15 minutes, giving us an opportunity to sort out our gear. (Uncruise provided us with wetsuits (which I wore on the boat), snorkels, and flippers for the duration of our seven-day journey.)
Once inside the protected area, Alex, Fun Baha’s guide, gave a short talk on whale shark 101 then went over the rules of engagement:
- Follow her directions at all times.
- Don’t touch a whale shark or let yourself be touched. We’re at fault if a whale shark gets too close.
nine feet from the shark. at least Snorkel closerto the head. The tail can do some damage if you accidentally get in theway.
briefed, we were on the lookout for our target megafauna. It wasn’t five
minutes before we spied the tell-tale white spots of a whale shark glistening
under the waves in the distance.
breath caught with excitement and a dollop of dread. Please don’t let me
freak out again.
The plan was to bring the boat alongside the fish as it swam, jump in the water and swim like one might run next to a slow-moving train. We’d stay in the water as long as we could keep up.
Per Maria’s instruction, the three of us who wanted to snorkel (the rest preferred to watch from the boat) sat at the edge of the swim platform at the stern of the Carolina. Snorkel, mask, and flippers on and ready to go. She pointed to the shark up ahead to our left. Seconds later, she waved us forward like a SEAL commander directing her team and then disappeared into the froth.
I pushed off from the boat and landed in a cocoon of bubbles and the shocking embrace of cold water. When my vision cleared, he was there: Large. Spotted. Glowing from the sun filtering through the murky blue. The other two guests and Sarah were close behind and for a moment we were a jumble of hands and flippers as we each tried to get a good look and not kick each other in the face.
The whale shark was big. Really big. Maybe 20 feet long and moving languidly through the water. A fraction of its size, however, I had kick hard to keep up. Thankfully, I was too captivated to be scared and the worry of reliving the shame of my Costa Rica encounter vanished.
For a moment, I lifted my head to locate Maria and was struck by the difference in views. Above the rolling waves, I could see our boat, my companions’ snorkels reaching toward the sky, and puffy white clouds crossing a bright horizon. In contrast, below, I could only see the solitude of a single graceful behemoth gliding through its milky domain. Perhaps that’s what intrigues and frightens me about the ocean. It’s so alluring, yet there is so much going on I can’t see beneath.
Our gentle giant banked slightly to the right and then put on the breaks, his lower half swinging like a slow-motion pendulum until he was upright. He’s going vertical!
mouth opened wide and I could see a little tornado of spinning water form as he
sucked in. When his mouth closed his gills rippled as if in a stiff breeze from
his exhalation. Again, his mouth opened and closed, and as he did so he rotated
until I could see his broad back and the stunning pattern of dots and lines
that made up his unique signature.
Swimming again, he came toward us. We backed away furiously and to the side to get out of his way but moments later it seemed as if he were coming at us again. I wasn’t frightened, it wasn’t aggressive. But between the power with which he propelled himself and the waves sweeping me in his direction, I thought for sure we were going to crash.
Again, and again we moved and he seemed to follow, swimming in a large circle, drawing in water in slow rhythmic gulps. He spent nearly 20 minutes allowing us to gawk at him.
And then tired of us I suspect, he swam away. Disappearing into the murky blue deep from whence he came.
I was UnCruise’s invited guest in the Sea of Cortez. Words and sentiment are my own.
