Fig. 1. The experimental set-up for tethering experiments. (A) We recorded the tail motion of a larva and the deflections of the tether to which a larva was attached. The larva is illustrated with the orientation that allowed for the recording of lateral forces: the longitudinal axis of the body is perpendicular to the direction of deflections. To measure thrust, the longitudinal axis was aligned parallel to the deflections of the tether. (B) The ventral perspective of a larva was recorded with video camera #1 mounted to a dissecting microscope mounted beneath the glass tank. (C) Deflections of the glass tether () were recorded by video camera #2 mounted to a compound microscope.
