There’s a whole other world waiting just beneath the surface in Hawaii. Think sea turtles cruising through the reef, bright tropical fish weaving through coral, and all sorts of interesting creatures crawling along the ocean floor. Whether it’s your first time snorkeling or you’ve done it before, exploring underwater Hawaii is something you won’t forget. In this blog, we’ll walk you through some of the marine life you’re likely to spot out there—and why it’s worth grabbing a mask and diving in.
Why Are Hawaii’s Waters So Unique?
Hawaii’s waters are home to one of the most unique and isolated coral reef ecosystems in the world. Because the Hawaiian Islands are located over 2,000 miles from the nearest continent, many of the marine species found here evolved in total isolation, resulting in a high level of endemism, meaning they exist nowhere else on Earth. The coral reefs surrounding Oahu provide a vibrant, shallow-water habitat that’s perfect for snorkeling, especially in the calm, clear conditions near Waikiki and Kewalo Harbor. These sheltered areas make it easy for beginners and families to safely explore underwater Hawaii and spot colorful fish, sea turtles, and other incredible creatures. If you’re looking to experience it for yourself, check out our Waikiki Snorkeling and Wildlife Cruise—an unforgettable adventure designed for all ages and skill levels.
Hawaiian Sea Turtles (Honu)
One of the most iconic and beloved marine animals in Hawaii is the Hawaiian green sea turtle, or honu. These gentle creatures are a top sighting on many snorkelers’ wish lists and are commonly spotted in areas like Turtle Canyons off Waikiki and along the island’s shallow reef ledges, where they find food and safe places to rest. Locations like Laniakea Beach on the North Shore are also known for frequent turtle activity. At Turtle Canyons in particular, the unique reef formations create natural ledges where turtles can tuck themselves in between feedings. If you’re hoping to swim near these amazing animals, Living Ocean’s Turtle Canyons Snorkel Excursion offers a respectful, family-friendly way to see them in their natural habitat. Just remember to give turtles plenty of space—stay at least 10 feet away, avoid standing directly in front of them since they can’t swim backward, and never block their path to the surface. And of course, never touch or attempt to ride a turtle—it’s harmful to them and against the law.
What Kinds of Tropical Fish Can I See in Hawaii?
Hawaii’s coral reefs are teeming with tropical fish that are as colorful and captivating as the islands themselves. These vibrant fish often swim close to snorkelers, offering unforgettable up-close encounters. Their vivid colors, graceful movements, and curious nature make them a highlight of any snorkeling adventure. On tours like Living Ocean’s Waikiki Snorkeling Tour, guests frequently spot a variety of native reef fish, including:
-
Reef Triggerfish – Humuhumunukunukuapua‘a
-
Butterfly Fish – Lau-Wiliwili Nukunuku‘oi‘oi
-
Black Durgon Triggerfish – Humuhumu ‘Ele‘ele
-
Parrotfish – Uhu
-
Trumpetfish – Nunu
-
Sergeant Major – Mamo
-
Bluestriped Snapper – Puhi
-
Saddle Wrasse – Hinalea Lau-wili
These reef fish play an important role in the marine ecosystem and are a joy to watch as they dart through coral formations and shimmer in the sunlight.
Coral Reefs and the Creatures That Live There
Coral reefs in Hawaii aren’t just beautiful—they’re alive. Made up of tiny animals called polyps, corals form the foundation of the reef ecosystem and provide shelter for countless marine species. While snorkeling, you might spot reef residents like starfish, sea urchins, eels, and crabs nestled among the coral. It’s important to never touch or stand on the reef, as even a gentle step can damage these delicate organisms. On guided experiences like Living Ocean’s Waikiki Snorkel & Waterslide Tour, you’ll learn how to explore responsibly while discovering the wonders of Hawaii’s underwater world.
Rare or Seasonal Wildlife Sightings
Every snorkel trip in Hawaii is a little different, and part of the magic is not knowing exactly what you’ll see. While reef fish and turtles are commonly spotted, lucky snorkelers may catch a glimpse of rarer marine life, such as:
-
Octopuses
-
Rays
-
Hawaiian monk seals
-
Dolphins
These sightings can be occasional and seasonal, but they add an extra layer of excitement to your underwater adventure. No matter what you encounter on Living Ocean’s Waikiki Snorkeling Tour, each experience offers a chance to explore with curiosity and respect for Hawaii’s incredible marine life.
Tips for Spotting Hawaii Marine Life While Snorkeling
