Snorkel in Waikiki often enough and you might get lucky with one of Hawaii's rarest sights: a Hawaiian monk seal. These gentle, whiskered animals are found nowhere else on the planet, and seeing one gliding through the water or dozing on the sand is a special moment. It also comes with responsibility. Here is what these seals are, why they matter so much, and exactly what to do if you meet one.
What Is a Hawaiian Monk Seal?
The Hawaiian monk seal, known in Hawaiian as ilio holo i ka uaua, or "dog that runs in rough water," is one of the most endangered seal species on Earth. Only around 1,500 remain, and they live only in the Hawaiian Islands. Most stay in the remote northwestern islands, but a growing number now call the main islands, including Oahu, home. That is why a snorkeler off Waikiki has a real, if slim, chance of crossing paths with one.
🥪 Monk Seal Quick Facts
- Found only in Hawaii, and among the rarest seals in the world.
- Around 1,500 are left in the wild.
- Protected under both federal and Hawaii state law.
- They rest on beaches and hunt on the reef, so keep your distance in both places.
Why They Need Their Space
Monk seals are protected under the Endangered Species Act and the Marine Mammal Protection Act, plus Hawaii state law. That means it is illegal to touch, chase, feed, or disturb them. They come ashore to rest, warm up, and care for their pups, and interrupting that rest can genuinely harm them. Giving them room is not just polite, it is the law and it helps this fragile species survive.
What to Do If You See One
The rule is simple: give the seal plenty of room and let it be. Experts recommend staying at least 50 feet away on land and even farther in the water, and never getting between a seal and the ocean or a mother and her pup. A common tip is the "rule of thumb": hold your thumb up at arm's length, and if it covers the whole seal, you are far enough away.
- Keep at least 50 feet of distance, more if a pup is present.
- Never touch, feed, chase, or try to swim toward a seal.
- Stay quiet and calm, and keep pets well away.
- If a seal seems sick, tangled, or harassed, report it to the NOAA statewide hotline.
