Abstract

We studied the haematology of the little penguin, Eudyptula minor, and measured red cell enzymes, and the rate of O2 and glucose consumption and CO2 and lactate production of whole penguin blood. 2. Little penguins have a very low RBC count (1.66 x 10(12) l-1) and very large red cells (MCV = 229 microns 3), resulting in a normal haemoglobin and haematocrit. 3. Despite the lower body temperature of penguins, the rate of O2 consumption by whole blood is close to that predicted from studies on other birds.

摘要

我们研究了小企鹅（小蓝企鹅，Eudyptula minor）的血液学，测量了红细胞酶，以及全企鹅血液的氧气和葡萄糖消耗率、二氧化碳和乳酸生成率。2. 小企鹅的红细胞计数非常低（1.66×10¹² 升⁻¹），红细胞非常大（平均红细胞体积 = 229 立方微米），但其血红蛋白和血细胞比容正常。3. 尽管企鹅的体温较低，但全血的氧气消耗率接近根据对其他鸟类的研究预测的数值。
