Floral electric fields signal to bees
Flowers have varying electrical fields that can be sensed by bees and attract them to come pollinate the flower.
Chemical and Electrical Signals
High salt levels recruit aversive taste pathways
High salt levels hijack bitter and sour neural pathways to make your food taste gross (and keep your electrolytes balanced!)
Corals cue fish to remove seaweeds
Corals use chemical signals to attract mutualistic fish that remove competing seaweeds that would otherwise hinder coral growth.
