Abstract
Blood volume in the hemoglobinless Antarctic icefish Chionodraco hamatus (Channichthyidae) has been determined by the Evans blue dye dilution technique. A mean blood volume of 127.0 ± 5.0 ml kg^−1^ body weight was found, a value even higher than that previously found in another icefish, Chaenocephalus aceratus (mean blood volume, 89.7 ml kg^−1^ body weight; Hemmingsen and Douglas [1970] Comp. Biochem. Physiol., 33:733–744; Twelves [1972] Br. Antarct. Surv. Bull. 37:85–92). This extraordinary hypervolemia appears unique among teleosts and may compensate for the absence of hemoglobin in the icefish. © 1995 Wiley‐Liss, Inc.
