缺氧已被证明会引起许多不同后生动物物种的行为体温过低，所有这些后生动物都有神经系统。原生动物，草履虫尾，没有神经系统，预计不会显示行为体温过低。然而，这种物种也被发现在低氧条件下的热梯度中选择较低的温度。这种反应被证明是有益的，因为在较低的温度下，缺氧副神经元的存活率大大增加。这种单细胞物种可能提供了一个有用的模型，研究适应性体温调节行为的细胞和分子基础。
Hypoxia has been shown to elicit behavioral hypothermia in a number of different metazoan species, all with nervous systems. The protozoan,Paramecium caudatum, has no nervous system and was not expected to display behavioral hypothermia. However, this species was also found to select a lower temperature in a thermal gradient under hypoxic conditions. This response proved to be beneficial as survival of hypoxic paramecia was greatly increased at lower temperatures. This unicellular species may provide a useful model to investigate the cellular and molecular basis of adaptive thermoregulatory behavior.
