Date:Reported: Unidentified https://www.inaturalist.org/observations/61016200
Observation: Direct original iNaturalist page and photograph reviewed. Two live harbor seals are side by side on a low rock surrounded by water. The page clock is inconsistent with Massachusetts, so no observation time is preserved.
