1. Hawaiian Green Sea Turtles (Honu)
Use your snorkeling resources to discover these gentle creatures. They are often seen near rocky reef locations where they feed on algae and seagrass. Even though sea turtles are docile, exercise caution to maintain a safe distance and not touch them. It is against the law both federally and at the state level to touch or disturb sea turtles.
The waters are often cooler and calmer in Hanalei in the afternoon, where snorkelers can continue without disturbing these animals.
2. Humuhumunukunukuāpua‘a (Reef Triggerfish)
This is Hawaii’s state fish! Humuhumunukunukuāpua‘a is a fun word to say, and it is a fun fish to see! They are easy to recognize because of their bright colors, bold stripes, and unique shapes. You’ll see them often at Kauai’s reefs. Watch as your captain and guide identify humuhumunukunukuāpua‘a as they dart between coral heads and on the bottom, leaving a trail of algae.
3. Parrotfish (Uhu)
Named for their strong, beak-like mouths, parrotfish play a vital role in maintaining the reef ecosystem. They feed on algae growing on coral, helping to keep reefs healthy. These fish are easily spotted thanks to their bright blues, greens, and pinks—and their habit of swimming in small groups.
If you’re lucky, you might even hear them munching away on the coral underwater!
4. Yellow Tang
Though tiny, these eye-catching yellow fish are difficult to overlook. Often found swimming in schools near coral reefs, yellow tang add vibrant color to the underwater landscape. They’re known for their oval shape and are usually seen feeding on algae-covered rocks.
Afternoon light often enhances their color, creating a beautiful contrast against the coral.
5. Moorish Idol
With long trailing dorsal fins and a pattern of black, white, and yellow, the Moorish idol is one of the most visually stunning fish you’ll see while snorkeling. While they may resemble the popular aquarium fish from animated movies, spotting one in the wild is much more memorable.
They’re usually found swimming in pairs or small groups and are common in the waters off Hanalei.
