Horseshoe Crab

About

How horseshoe crab lives

Horseshoe crabs are ancient marine arthropods that gather on beaches to spawn during high tides. Horseshoe crabs are more closely related to spiders than to true crabs. Coastal species are often adapted to tides, wind exposure, and rapidly changing shorelines.

Conservation

Status and habitat pressure

Vulnerable species face mounting risks and can decline quickly if habitats continue to shrink. Protecting horseshoe crab also depends on keeping coast, ocean habitats healthy and connected.

Vulnerable species can decline quickly when habitat loss, climate pressure, or human conflict intensifies.
