Horseshoe crab pair 3©JMacCausland.

Add to Lightbox

American Horseshoe crabs (Limulus polyphemus) are mating off Provincetown, Massachusetts, USA. They will travel, hitched together, along the slopes of Cape Cod Bay. If you're wondering how the male in the rear holds on, as I was, see my images in the DELMARVA Gallery on my site, where I show the Pedipalps. Their blue blood is used in detecting bacterial endotoxins. Once widespread in ancient seas, only a few live in the modern world. We use them also for fertilizer and bait. They are harmless to us. The telson or tail is not a weapon, but used to right itself if turned upside down in surf, or other predicament. Slipper limpets are commonly attached to their exoskeleton. Horseshoe crabs have lateral compound eyes and good night vision. They are arthropods.
