Mullus (Spondylus)

"Mullu" is the name under which the inhabitants of ancient Peru knew the products of a shell that live in warm seas in the north. The pickup of mullu (Spondylus princeps) were fishermen, who knew he had to dive to several meters deep to find it; only exceptionally was near the surface. There mullu in warm seas of Ecuador, rather than those of Peru.

Observing the behavior of animals and plants is a good method of prediction. You can measure fluctuations in temperature marine recording the conduct of marine fauna. They are animals very sensitive to changes thermal and some, like Spondylus, particularly sensitive. When there is "mullu" (Spondylus princeps) near the coasts is that the water is warm. In a few months of that change, effects on air temperature and evaporation of water will be sensitive and climate change. If you have news about the behaviour of mullu and other animals, and combines this information with the observations available on other indicators of climate and the date fixed recurring cosmic phenomena, it will have a timetable to reduce the risks versus agricultural events unexpected. Chavin leaders (priests) knew all about this.
