JEB01575 Supplementary Material

Files in this Data Supplement:

• Movie 1 -

  Movie 1.  Sonogram of a midsagittal section through the cuttlefish, showing the anterior vena cava, branch point, ventricle and mantle. 

  For organ identification, see the legend in Fig. 3B.  NB Videos are rotated 180� from their still counterpart.  The peristaltic contractions of the anterior vena cava (AVC) had the same rate as the contractions of the mantle (m), but were out of phase with them.  The anterior vena cava had a different contraction rate than the branch point (BP) and the ventricle (V).  The branch point and the ventricle, however, shared the same contraction rate.

• Movie 2 -

  Movie 2.  Sonogram of a transverse section through the branch point, the efferent branchial vessels, the gills, and the mantle. 

  For organ identification see the legend in Fig. 3C.  NB Videos are rotated 180� from their still counterpart.  Notice how the gills move back and forth, but do not appear to contract.  The branch point (BP) and the left efferent branchial vessel (EBV), however, contract noticeably at about the same rate, but out of phase with each other.
