Starfish in Hawaii: Identification Guide and Where to Start Looking

1. What are the key identification markers for starfish in Hawaii?

To identify a starfish in Hawaii, count the arms first. Most species have five arms, but some like the Crown-of-Thorns have more. Look at color and surface texture. The Blue Linckia is bright blue with smooth skin, while the Chocolate Chip starfish has brown bumps. Check the center disc size and tube feet arrangement.

2. Which starfish species are most commonly seen in Hawaii?

The most common are the Blue Linckia (Linckia laevigata), the Crown-of-Thorns (Acanthaster planci), and the Chocolate Chip starfish (Protoreaster nodosus). The Blue Linckia is vivid blue with slender arms. Crown-of-Thorns has long, venomous spines. Chocolate Chip is tan with dark tubercles. Lookalikes include brittle stars, which have thinner, more flexible arms and move quickly.

3. Where in Hawaii are you most likely to spot starfish?

Best odds are in shallow, protected waters. Hanauma Bay on Oahu offers easy snorkeling and frequent sightings of Blue Linckia. Tide pools along the Kona coast of the Big Island often hold small starfish. On Maui, check the rocky areas near Kapalua Bay. Avoid touching them, as some species like Crown-of-Thorns can sting.

4. How can you tell starfish apart from similar marine animals?

Brittle stars are the main lookalikes. They have long, whip-like arms that move more snake-like. Starfish have thicker, more rigid arms with tube feet underneath. Sea urchins are round and spiny, not star-shaped. Some starfish mimic coral or rocks, so look for the five-ray symmetry.

5. What is the best time of year and day to see starfish?

Year-round, but low tide exposes tide pools, making starfish easier to see. Early morning or late afternoon are best for calm, clear water. Summer months (May to October) have the best visibility. Winter swells can stir up sand and reduce visibility.

6. What should you bring for starfish spotting in Hawaii?

Bring a mask and snorkel for shallow reefs. A waterproof camera or phone case helps document finds. Wear reef-safe sunscreen to protect both you and the animals. A field guide to Hawaiian starfish can help with on-the-spot ID. Check out more tips at ourwildlife in Hawaii page.

7. How to document your starfish sightings responsibly?

Take photos from above without touching. Note the date, location, depth, and water conditions. Use a measuring reference like a coin next to the starfish (but never remove it from water). Share sightings on citizen science platforms like iNaturalist. Learn more aboutstarfish identification.
