An IUCN Red List assessment found that the American horseshoe crab (Limulus polyphemus) is at risk of extirpation in some regions of its range where small and vulnerable populations occur.
Notes on verification
Directly confirmed by the IUCN Red List assessment itself, with corroboration from USFWS species status documentation citing the same source. Multiple independent secondary sources echo the finding, though ultimate origin traces to one primary assessment.
