September 18, 2025 — Researchers at Norwalk, Connecticut, U.S.A.-based The Maritime Aquarium claim new studies show a “troubling decline” in the horseshoe crab population within Long Island Sound.
“Horseshoe crabs are a cornerstone of estuarine ecosystems, and their decline is alarming in its own right but also has cascading consequences for other animals and ecological processes,” Maritime Aquarium Vice President of Conservation Sarah Crosby said in a release.
