The V-notch system and its movement in a suction organ from Liponeura cinerascens. (a) Selected frames from in vivo IRM recording showing the V-notch being pulled open from the flanks (see Additional file 6 for the full video). (b) Confocal microscopy image of a Congo Red-stained suction organ reveals the two apodemes attaching to the V-notch flanks (see arrows) that mediate active muscular control of the V-notch.
