February 20, 2026 — NOAA Fisheries has denied Endangered Species Act protections for the Atlantic horseshoe crab, a lumbering species whose unique blood is highly valued by the biomedical industry.
Faced with two petitions that urged designating the species as either threatened or endangered, the federal agency instead concluded no ESA listing was warranted.
“There has been improvement in the population status and trends of regional populations from New Hampshire to Florida-Atlantic, with the exception of New York,” NOAA Fisheries announced this week, adding that “the petitions rely on obsolete and incorrect information to infer the current status and trends of the species.”
