Snorkeling on the Nā Pali Coast is an adventure-packed activity that’ll open you up to the beautiful undersea world. There’s nothing quite like the rush of being up close and personal with unique, colorful fish in their natural habitat. To help prepare you for this exciting experience, here are four varieties of fish to look out for.

4 Fish to Spot When Snorkeling

1. Humuhumunukunukuapua'a

Also known as the rectangular triggerfish, the Humuhumunukunukuapua'a is the official state fish of Hawaii. Native to the saltwater coasts of the central and south Pacific Ocean islands, these small fish live in reefs and will typically hide in the crevices of rocks and coral. They can lock their spines as protection from predators, keeping them securely fastened to their resting hiding spots. The Humuhumunukunukuapua'a tends to be territorial, so be sure to give them space if you encounter them while snorkeling along the Nā Pali Coast.

2. Parrotfish

With its beak-like mouth, the aptly-named parrotfish is known to change shape, color, and gender throughout its lifetime. At night, this unique fish will cocoon itself in a veil of mucus to protect it from predators.

3. Yellow Butterflyfish

This butterflyfish has a bright yellow body and dorsal and pelvic fins. They’re found in Hawaii and the Indo-Pacific region either by themselves or in schools on reef flats. They’re a carnivorous breed and are typically a peaceful fish to come across while snorkeling.

4. Unicorn Fish 

Primarily active during daytime hours, unicorn fish are herbivores and typically swim in large groups. They’re often seen in outer reef areas in open water, particularly near drop-offs. You can easily spot them while snorkeling by their horned appearance, which they will sometimes use as protection against predator fish.
