Biggest Marine Animals Around Where to Dive With Them: North America Edition

There is something magical about diving in a massive body of water. Our perspective shifts and we feel small, but not insignificant. As humans, we tend to think we run the show on this planet. But when diving next to an animal at least ten times our size, we’re humbled and awe-struck in a way that has the capacity to change us forever. The good news is that these massive animals in these massive oceans are found all over the world. Therefore, this incredible experience could be just a short trip from where you are and a dip into the sea. Let’s look at some of the biggest animals that swim around North American water and where to go diving with them. 

Blue Whales

First off we have the largest animal ever recorded on earth, the Blue Whale. Weighing in at around 441,000 lbs, the blue whale can grow to a length of 80-100 feet long. Just their tongues weigh as much as an entire elephant. In addition to being the largest animal on the planet, they’re also the loudest animal on the planet, with their pulses and moans being heard by other whales up to an impressive 1,000 miles away! They are considered endangered since they were once heavily hunted years and years ago. They’re found in all the world's oceans (except for the Arctic) but we have the greatest odds of running into them on a dive around the California coastline, specifically near either San Diego or Monterey Bay.

Lion's Mane Jellyfish

The Lion's Mane Jellyfish is a true marvel of the ocean, gracefully drifting through the colder waters from the Pacific Northwest all the way up to Alaska. Imagine spotting one of these mesmerizing creatures with its tentacles extending an astonishing 120 feet long—yes, you heard that right! That’s longer than a blue whale! When you catch a glimpse of its bell-shaped body adorned with up to 1,200 delicate tentacles divided into eight clusters, it really does resemble a lion’s mane flowing in the currents. These ethereal beings are mostly found in the first 20 meters below the surface, where they float serenely amid schools of fish and swaying kelp forests. If you're lucky enough to encounter one while kayaking or diving off Washington’s coast, you'll witness nature at its most majestic; it's as if you've stepped into an underwater fairy tale where giants roam and every ripple tells a story.

Sperm Whales

In the crystal-clear waters surrounding Dominica, the Caribbean's hidden gem, you can find the majestic Sperm Whales gracefully navigating their underwater realm. These giants of the ocean are truly remarkable; as the largest of toothed whales, males can reach impressive lengths of up to 52 feet while females typically grow to around 40 feet. Once hunted for their prized spermaceti oil—used back in the day for lamps and candles—their numbers took a significant hit, leading them to be labeled as endangered. Dominica stands out as one of the best spots globally for diving with these incredible creatures, home to over 200 resident sperm whales. Imagine yourself plunging into depths where they often roam, capable of diving down an astonishing 10,000 feet—not that you’ll be going down that far, but hey, they have to come up for air every now and then!

Whale Sharks

Whale Sharks, the gentle giants of our oceans, are not just your average fish—they're the largest fish in the sea! Technically classified as sharks (not whales, despite their name), these magnificent creatures can reach lengths of around 12 meters, with some individuals stretching an impressive 20 meters long and tipping the scales at a whopping 20 tons. Imagine swimming alongside one of these beauties while exploring South Florida or Southern California waters! However, it's important to note that life isn't easy for whale sharks; only a small fraction make it into adulthood due to various threats they face. Those lucky enough to survive can live up to an astonishing 150 years old—talk about longevity! Gliding through warm ocean currents at a leisurely pace of about 3 mph, they embark on epic migrations covering thousands of miles. If you're thinking about spotting them in action, head to places like The Bahamas from December to early March or dive into Mexico's vibrant seas around Cancun and Baja California Sur. But don't forget: they're currently on the endangered list and need our protection just like other shark species out there facing similar challenges.

Great White Sharks

Great White Sharks, those magnificent apex predators of the sea, can grow up to an impressive 16-20 feet and are arguably one of the most popular—and feared—shark species out there. With their 300 razor-sharp teeth designed for slicing rather than chewing, they take a big chunk out of their prey and swallow it whole, showcasing nature's efficiency at its finest. If you’re dreaming of an adrenaline-filled adventure diving with these giants, think again; this experience isn't exactly common and is typically done from underwater cages for that extra layer of safety. Your best chances to catch a glimpse of a Great White in North America? Head over to the stunning Southern California coastline or even venture around the islands of Hawaii—you might just be lucky enough to spot one! You may happen across one around northern Florida too.

Tiger Sharks

Tiger Sharks are some of the most stunning creatures you’ll ever encounter in the ocean. With their striking striped patterns that almost look like nature's art, these magnificent predators can grow up to 18 feet long—just a tad shorter than the great white—and they weigh in at an impressive 2,000 lbs! They thrive in shallow, warm coastal waters where they often make appearances. If you’re lucky enough to dive at Tiger Beach in the Bahamas, you'll find yourself surrounded by these beautiful creatures; it’s a hotspot frequented by multitudes of tiger sharks that draw divers from all over who are eager for an unforgettable experience. They can also be spotted pretty regularly around South Florida and the waters around Hawaii. Whether you're swimming alongside them or just observing from your boat, there's something magical about watching them glide gracefully through their vibrant underwater world.

Humpback Whales

Humpback Whales, often seen gracefully gliding through the warm waters of Hawaii, are truly a sight to behold! These magnificent creatures can grow up to 60 feet in length and weigh as much as 80,000 pounds—imagine that! With lifespans reaching an impressive 80-90 years, humpbacks have plenty of time to chow down on their favorite meals; they feast on about 3,000 pounds of krill and small fish each day. Named for the distinctive hump that adorns their backs, these gentle giants migrate thousands of miles every year during winter months just to bask in the sunny Hawaiian seas where they mate and give birth. The sheer joy of watching them breach or hear their haunting songs echoing underwater is an experience like no other.

Giant Oceanic Manta Ray

When diving in the waters off South Florida, California, and Hawaii, you might just encounter the Giant Oceanic Manta Ray—truly a marvel of marine life! These gentle giants can stretch an astonishing 29 feet across their wingspan and weigh up to a whopping 5,300 lbs. Imagine gliding through the ocean alongside such an impressive creature! They have a lifespan that can reach up to 40 years, and these rays also showcase some serious brainpower; they have the largest brains of any fish studied so far. That's right—their smarts allow them to exhibit excellent memory skills and even recognize themselves in mirrors! When you're lucky enough to spot one of these massive rays cruising gracefully through the sea beneath sunlit waves, you'll understand why they inspire awe among all who share their oceans.

Now go get wowed by some of nature’s largest animals now that you know where to dive with them. Always remember, these are wild animals and you’re in their homes, so keep your distance and stay respectful and dive responsibly.
