Seed-Spitting Mice

These two video clips show two species of spiny mouse — first the golden spiny mouse, and then the common or Cairo spiny mouse — eating fruit from the shrub Ochradenus baccatus and spitting out the seeds. If the seeds are chewed with the fruit, a chemical reaction creates a “mustard oil bomb,” so the mice have learned to spit out the seeds while eating the fruit.  Credit: Samuni-Blank et. al., Current Biology
