Animals were grown on a lawn of E. coli constitutively expressing GFP, in which the fluorescent intensity in the outer 40% of the lawn (border) is 35% brighter than in the inner 60% (center), suggesting differences in bacterial density.
Animals moved more quickly on food than solitary foragers even though in the absence of food, both social and solitary foragers moved at similar rapid speeds. When moving on food, social animals made long forays at speeds of ~190um/s until they joined a clump, at which point they reduced their speed and reversed frequently.
Animals exhibited a decrease in the fluorescence ratio of GFP expressing bacteria between the border and center of the lawn. Animals primarily consumed bacteria at the border of the lawn.

Between 20 and 48 hr, the fluorescence levels of GFP expressing bacteria decreased ~1.2% per hour, which was the same rate observed for N2 animals on a similar lawn of bacteria.

Animals were not significantly more susceptible to infection by P. aeruginosa than N2 animals, unlike npr-1(g320) mutants in an N2 background, which was hypersusceptible to P. aeruginosa infection.
