Parameters That Effect Brine Shrimp Pattern Selection

Self-propelled particles are physically rich systems that are also relevant in biology such as microorganisms, schools of fish, flocks of birds, and even human crowds. This poster will cover the preliminary experimental work of the collective motion of Artemia franscicana otherwise known as brine shrimp. Large collections of these shrimp will aggregate in such a way that they will form spatial patterns, which depend on environmental properties that play into the driving and dissipation of the system. Also, the natural phototaxis of shrimp, especially 1^st instar stage shrimp, effect pattern selection. We look a bit at the individual properties such as shrimp speed and how that is affected by age i.e. size. These differences can cause a phase separation to occur where shrimp separate into slower and faster swarms and causes spatial patterns in three dimensions.
