respectively (mean±SD; number of observations in parentheses). In
addition to differences in capillary size (Fig. 3), those of the icefish show
an unusual architecture.
Fig. 3. Electronmicrograph of skeletal muscle capillaries from Chaenocephalus aceratus
(top, scale bar = 10 Ilm) and Oncorhynchus mykiss (bottom, scale bar = 5 Ilm) illustrating
the similar fine structure, but contrasting endothelial cell thickness and cross sectional area.
