Horseshoe Crab ... Thai Asian Street Food Key Ring

Horseshoe crabs are arthropods that live primarily in and around shallow ocean waters on soft sandy or muddy bottoms. Horseshoe crabs are considered living fossils. Unlike mammals, horseshoe crabs do not have haemoglobin in their blood, but instead use hemocyanin to carry oxygen. Because of the copper present in hemocyanin, their blood is blue. WARNING DO NOT EAT THEM when in Thailand, Tetrodotoxin may be present in the roe. Go Isaan Photography specialises in idiosyncratic imagery from Thailand, Cambodia and Laos.
