O2 delivery in Notothenioidei. Retinal micrographs of (a) C. aceratus (b) N. co riiceps demonstrate the difference in capillary density and intervessel distance (IVD) between the two fish. Reprinted with permission from Wujcik et al.52. (c) These decreased intervessel distances help compensate for blood O2 levels in C. aceratus. A similar effect should act on other solute (e. growth factors or drugs) diluted by larger blood volumes as well. Equation (1) solved numerically using MatLab and data from Refs. 17, 40, 52 and 53; full list of parameter values can be found in Supplementary Information S1.4.
