Fig. 7. Contraction pattern and main contraction states of two fused individuals (Tw 1 and Tw 2) of T. wilhelma. (A) Both individuals in expanded phase. (B) Tw 1 in contracted phase, Tw 2 in expanded phase. (C) Both individuals in contracted phase. (C) Tw 1 in expanded phase, Tw 2 in contracted phase. Bars, 5 mm. (E) Contraction patterns of Tw 1 and Tw 2 and both together (Tw 1+2) over 24 h. A^*-D^* are contraction states represented by images A-D. The time-lapse series used for this measurement is shown in movie S5 in supplementary material.
