Each species of slime mold has its own specific chemical messenger, collectively referred to as acrasins.[1] These chemicals signal that lots of individual cells should move towards each other to form a single large cell or plasmodium. One of the earliest acrasins to be identified was cAMP, found in the species Dictyostelium discoideum by Brian Shaffer[2], which exhibits a complex swirling-pulsating spiral pattern when forming a pseudoplasmodium.[3]
