Fig. 7. The phase shift between the mantle and the anterior vena cava (AVC) plotted
against the ventilation rate: heart rate ratio.
Fig. 6 shows the variation in
the phase shift between mantle and AVC contractions between animals. This
variation is largely explained by how many times the mantle contracts per
heart contraction (linear regression: r2=0.98,
P=0.0082, N=4). Each symbol represents averaged data from
one cuttlefish.
