Grouped by each record’s archive date. Approximate dates keep their original labels in the records below.

  1. Cape Cod National Seashore Massachusetts
    Unidentified https://www.inaturalist.org/observations/545992

    Direct original iNaturalist page and photograph reviewed. Three live seals are swimming with three visible heads. Identification discussion singles out the left animal as Grey Seal, but the mixed group species assignment remains uncertain. Species not recorded · 3 seals

  2. Coastal waters off Portland Maine
    Unidentified https://www.inaturalist.org/observations/197743794

    Direct original iNaturalist page and photograph reviewed. One live Harbor Seal is on a coastal rock. The observer says the geotag is not exact, so the broad coastal-waters location is used. Harbour seal · 1 seal

  3. Provincetown Massachusetts
    Unidentified https://www.inaturalist.org/observations/150541141

    Direct original iNaturalist page and photograph reviewed. One live Grey Seal is swimming; public map is obscured and no subspecies claim is made. Grey seal · 1 seal

  4. York coast, Gulf of Maine Maine
    Unidentified https://www.inaturalist.org/observations/53402174; https://www.inaturalist.org/observations/53402610

    Direct original iNaturalist pages and photographs reviewed. The same observer recorded two public points about 80 metres and 32 minutes apart: one live seal on wet rocks and about three seals swimming. These are grouped as one outing/group encounter. Harbor and Grey Seal IDs disagree, so species and count remain unset; displayed clock omitted.

  5. Nantucket Massachusetts
    Unidentified https://www.inaturalist.org/observations/52669629

    Direct original iNaturalist page and photograph reviewed. One decomposed seal carcass is on sand at an obscured Nantucket location. Current Harp Seal attribution is retained as probable; no cause of death is inferred and the displayed clock is omitted. Harp seal · 1 seal

  6. Southwest Harbor Maine
    Unidentified https://www.inaturalist.org/observations/140284825

    Direct original iNaturalist page and photograph reviewed. One live Harbor Seal is swimming; no subspecies claim. Harbour seal · 1 seal
