Horseshoe crab (F. Limulidae)
Chek Jawa, 20th September 2008
Note to self: I need to inspect all horseshoe crab carcasses and moults more carefully in future. I've been automatically assuming that any horseshoe crabs (or remains of horseshoe crabs) encountered outside of a mangrove setting are coastal horseshoe crab (Tachypleus gigas), when there is a high chance that they could have been mangrove horseshoe crab (Carcinoscorpius rotundicauda).
