Additional file 1: of Morphology of powerful suction organs from blepharicerid larvae living in raging torrents

Figure S1. Freeze-fracture SEM image of a Liponeura cinerascens suction disc showing spine-like microtrichia. The spine-like microtrichia are similar in shape to those found in L. cordata (see Fig. 5b). Arrow points towards the centre. Scale bar 5 μm. Figure S2. Thread-like attachments between piston muscles and the piston cone. From Liponeura cordata micro-CT data. (a) Lateral view of piston cone shows a void volume where the thread-like attachments connect the ends of the muscles to the top of the piston cone. Arrows indicate thread-like attachments. A: anterior, P: posterior, L: left, R: right. Scale bar 50 μm. (b) 3D rendering highlighting the thin fibrous nature of the thread-like attachments.
