Common name: Horseshoe Crabs

Scientific name: Xiphosurida

Xiphosurida, commonly known as horseshoe crabs, are not true crabs but are more closely related to arachnids. These ancient mariners are known for their distinctive, helmet-like carapace and long, pointed tail spine. In the hobby, they are appreciated for their unique appearance and for their role in consuming detritus, but they require spacious tanks with sandy bottoms to mimic their natural habitat. They are also known for their blue blood, which contains a substance used in medical testing.
