Marine Life in Hawaii: What You Might See While Snorkeling or Diving

Hawaii’s crystal-clear waters are home to some of the most colorful and unique marine life in the world. Whether you are snorkeling along Maui’s reefs or diving off the Big Island near Hilo, you are in for an unforgettable underwater adventure. Here’s a peek at what you might encounter when you dip beneath the surface.

Tropical Fish That Steal the Show

Hawaii’s reefs are alive with vibrant fish species you will not find anywhere else. The humuhumunukunukuapuaʻa, Hawaii’s state fish, is a crowd favorite with its bold patterns and fun name. You will also see schools of yellow tangs, parrotfish with their rainbow hues, and Moorish idols gliding gracefully through the water. These fish thrive around coral reefs, so keep your eyes peeled when exploring popular snorkeling spots like Molokini Crater in Maui or Richardson Ocean Park in Hilo.

Graceful Sea Turtles

Honu, or Hawaiian green sea turtles, are gentle giants often spotted grazing on algae in shallow waters. Maui’s Turtle Town and Hilo’s Carlsmith Beach Park are prime places to see them swimming slowly alongside snorkelers. Remember to admire from a distance, as sea turtles are protected by law in Hawaii and need their space to stay safe and healthy.

Playful Dolphins and Curious Monk Seals

Spinner dolphins often appear in pods off the coast of both Maui and the Big Island. If you are lucky, you may catch them leaping and spinning in the air during a morning snorkel or boat trip. Another rare but exciting encounter is the Hawaiian monk seal, one of the most endangered marine mammals in the world. Occasionally, these seals can be seen basking on remote beaches or swimming along the shoreline.

Majestic Manta Rays

If you want an unforgettable diving experience, consider a night dive with manta rays on the Big Island. These massive but gentle creatures glide like underwater birds, feeding on plankton attracted to the dive lights. While this activity is more common near Kona, adventurous travelers staying in Hilo can easily arrange trips to join in.

Seasonal Visitors: Humpback Whales

Between November and April, humpback whales migrate to Hawaiian waters to give birth and nurse their calves. While you will not see them underwater while snorkeling, you can often hear their haunting songs while diving. From the shore or on a boat, it is common to witness them breaching and slapping their tails on the surface. Maui, in particular, is famous for its whale-watching opportunities during this season.
