Southern New England Horseshoe Crabs Threatened
July 17, 2015
Older than dinosaurs, horseshoe crabs have survived plenty. But human impact may be the threat that could wash them out of the Atlantic, according to an article on EcoRI.org.
Horseshoe crabs used to be heavily hunted. In recent years, harvest quotas have been put in place to help the crabs. But they are still threatened. Today, these crabs have two big threats looming over their oddly shaped heads. Horseshoe crabs are a popular bait for conch and eel fishermen, and they are wanted for their blood. Horseshoe crab blood is used for biomedical research and product manufacturing involving the detection of gram-negative bacteria, which can be harmful to humans.
