Nice find, Jordan,

Also of some interest is the fact that the conspicuous blue pigment 
clearly shown in that report, hemocyanin, is present in the "blood" of 
most mollusks as well as the horseshoe crab.

Caveat 1: This stuff should not be confused with the substance that 
detects bacterial endotoxin (the core topic of the piece).
Caveat 2: Certain mollusks, e.g., Arks (Arcidae) use hemoglobin instead 
of hemocyanin the purpose of oxygen transport.
