Figure 5
Elastic recoil of a flagellum in the crab Carcinus after an imposed abduction movement. (A) Maxilliped 1. (B) Maxilliped 3. Each flagellum was abducted by imposed movement and then released. Selected frames captured at the times indicated after release are shown from sequences captured at 250 images s-1. (C) Graph of the average angular velocity of the recoil movement against the angular extent of abduction. The graph is based on 28 imposed movements of maxilliped 3, 16 of maxilliped 2 and 11 of maxilliped 1 from one male and two female crabs. The average velocity for all maxillipeds is plotted for 10° bins of angles moved. Scale bar in A and B 1 mm.
