...Kimberly A. Borley; Jody M. Beers; Bruce D. Sidell SUMMARY Antarctic icefishes possess several cardiovascular characteristics that enable them to deliver oxygen adequately in the absence of hemoglobin (Hb). To gain insight into mechanisms driving development of these cardiovascular characteristics...

... differences in vessel morphometries among notothenioid species. Hemoglobinless (–Hb) icefishes display mean vessel length densities that are greater ( Chaenocephalus aceratus , 5.51±0.32 mm mm –2 ; Champsocephalus gunnari , 5.15±0.50 mm mm –2 ) than those observed in red-blooded (+Hb) species( Gymnodraco...

... found in the pectoral muscle fibres of the icefish Chaenocephalus aceratus , which lacks the respiratory pigments haemoglobin and myoglobin. Red-blooded notothenioids found in the sub-Antarctic had a similar muscle fine structure to those caught south of the Antarctic Convergence, with an MFD of 20–41...
