Detailed views of the V-notch valve-like structures from Liponeura cordata, reconstructed from micro-CT data. (a) Sagittal view of a suction disc rendered to reveal internal structures. The V-notch flap juts out dorsally from the suction disc (marked with an asterisk) compared to the opposite (posterior) side of the disc and could function as a backwater valve to prevent influx of water during piston contraction (see Additional file 7). (b) Dorsal view of the V-notch valves showing their flap-like morphology. Note that the V-notch apodemes attach to the flanks of the flaps (arrows). Scale bars 30 μm
