Hawaiian monk seals are protected under the Endangered Species Act and Marine Mammal Protection Act, and Hawaii state law.

NOAA Fisheries has launched our "Species in the Spotlight: Survive to Thrive" initiative — a concerted, agency-wide, partnership-driven effort to highlight and save eight species identified as highly at-risk for extinction, including the Hawaiian monk seal. To support this initiative, we've developed 5-year Priority Action Plans for these species that focus our recovery actions on immediate, targeted efforts to reverse declining population trends.

Watch Good Neighbors Video - How to Share Hawaii's Beaches with Endangered Monk Seals


  • Maintain a distance of 150 feet and/or stay behind any protective ropes or signs. It is natural for monk seals to rest on the beach.
  • Never feed seals. It is unsafe and illegal.
  • Do not encourage or get close to monk seals on the beach or in the water. Monk seals are wild animals and will bite.
  • If a seal approaches you, ignore it, move away, and exit the water if necessary. Playful seals become problem seals when encouraged.
  • Keep dogs leashed at all times near monk seals. This prevents injury and disease transmission for both animals.
  • Fish with barbless hooks. Barbless hooks reduce seal injuries.

24-hour (toll-free) Marine Mammal Stranding and Entanglement Hotline: 1-888-256-9840
Help us by reporting all seal sightings and interactions. Your reports help NOAA Fisheries respond to hooked, or injured seals, track potential harmful seal behavior, and monitor the seal population. Learn about the Pacific Islands Marine Mammal Response Network.


  • Food Limitation
    Limited prey availability is the primary factor attributed to emaciation and poor survival of juvenile monk seals.
  • Human Interactions
    Human actions and activities are diverse and can adversely impact the survival of monk seals.
  • Infectious Diseases, Parasites
    and Toxins

    With a total population of only 1,100 individuals, any disease outbreak or immune system suppression at any of the seals' breeding and pupping locations can have devastating population-level impacts.


  • Enhance survival of female seals, especially juvenile pups born in the Northwestern Hawaiian Islands.
  • Ensure natural population growth and reduce human-seal interactions in the main Hawaiian Islands.
  • Prevent and mitigate disease and build seal health care capacity.
  • Administer a recovery program for maximum effectiveness integration and partnerships.
