Hawaii Marine Life Guide
Turtles
Sea turtles are among Hawaii's most beloved marine animals, often seen swimming near reefs, resting along rocky shorelines or basking on beaches. The Hawaiian green sea turtle, called honu, is the most common turtle species in Hawaiian waters.
Sea Turtles Overview
Sea turtles are graceful marine reptiles that surface for short breaths before returning below to swim, rest or feed. In Hawaii, they are among the most memorable animals visitors may see near reefs, rocky shorelines, calm bays and sandy beaches. Visitors can browse the broader Hawaii fish guide for more marine animal profiles.
Four sea turtle species inhabit Hawaiian waters: the Hawaiian green sea turtle, hawksbill turtle, leatherback turtle and olive ridley turtle. The green sea turtle, known in Hawaiian as honu, is the most common and the one most often seen by snorkelers and beachgoers.

Honu: Hawaii's Green Sea Turtle
The honu is the sea turtle most closely associated with Hawaii. These turtles often feed around reefs and rocky areas, where algae grows. They may also rest near shore or haul out onto beaches to bask in the sun.
Seeing a honu can feel special because the animal moves slowly and calmly through the water. However, sea turtles are wild animals and need space to rest, feed and travel without disturbance. Visitors can learn more about honu and their place in Hawaii's marine environment.
Other Turtle Species in Hawaiian Waters
The hawksbill turtle also occurs in Hawaii, though it is much rarer than the green sea turtle. Hawksbills have a narrower, pointed beak-like mouth and a patterned shell. Leatherbacks and olive ridleys are also present in Hawaiian waters, but most visitors are far less likely to encounter them close to shore.
Together, these species show the importance of Hawaii's waters for marine turtles, even though each species uses the ocean in different ways. Related marine animals include dolphins, whales, Hawaiian monk seals and Hawaii sharks.
Where Sea Turtles May Be Seen
Sea turtles may appear near coral reefs, rocky coastlines, protected bays and sandy beaches. Some popular viewing areas in Hawaii are known for turtle sightings, but sightings always depend on ocean conditions, time of day and natural turtle behavior.
When watching turtles, use patience. A turtle may surface briefly to breathe, rest quietly on the bottom or move slowly through reef areas while feeding. Visitors planning shoreline or reef time can also review Hawaii snorkeling, Hawaii beach safety tips and beach guides such as Hawaii beaches, Oahu beaches, Maui beaches, Kauai beaches and Big Island beaches.
Respectful Viewing
Sea turtles are protected wildlife, so visitors should never touch, chase, feed or block them. If a turtle rests on the beach, give it plenty of room and follow any posted signs or guidance from lifeguards and wildlife volunteers.
- Watch quietly from a respectful distance.
- Do not touch or ride a turtle.
- Do not block a turtle's path to or from the ocean.
- Keep fins, hands and cameras away from the animal.
- Let the turtle choose where to swim or rest.
Visitors who want guided ocean experiences can compare Oahu snorkeling tours, Maui snorkeling tours, Kauai snorkeling tours and Big Island snorkeling tours.
Why Sea Turtles Matter
Sea turtles play an important role in ocean ecosystems. Green sea turtles graze on algae, which helps maintain healthy reef and coastal habitats. Their long lives also connect them to many generations of Hawaiian shoreline and ocean history.
With their calm presence, long lifespan and Hawaiian name honu, sea turtles remain one of the most cherished animals in Hawaii's marine world.
