Fig. 1. The influence of feeding on the relative mass of the tissue (expressed as g
kg1 body mass) of various segments of the gastrointestinal
tract in the dogfish shark (A) stomach-1 (cardiac stomach), (B)
stomach-2 (pyloric stomach) and (C) intestine. The inset bars indicate the
mass contributed by the tissue water content, and the differences represent
the mass contributed by the tissue dry-matter content. Means ± 1 s.e.m.
(N=68 at each time point). Means not sharing the same letter
are significantly different (P<0.05); the same symbols apply to
the mass contributed by tissue water content and so have not been
repeated.
