Tadpole plasticity triggered by dragonfly nymph predation (video)

Professor Rick Relyea from the University of Pittsburgh gave a fascinating seminar today: "Phenotypic Plasticity: Stress-Induced Changes in Behavior, Morphology, and Life History of Aquatic Organisms".

He showed this amazing and somewhat scary video of dragonfly nymphs and tadpoles.

  1. That is indeed a slightly scary video. I knew that dragonfly nymphs were predators, and seeing them in action is amazing.

    1. The way it looks over at the tadpole is frightening.
