Abstract
The brain and eye of swordfish are warmer than the water. Associated with one of the eye muscles is a tissue that heats the brain. This brain heater is rich in mitochondria and cytochrome c and is supplied with blood through a vascular heat exchanger. It protects the central nervous system from rapid cooling during daily vertical excursions which may take the swordfish through a wide temperature range.
摘要
剑鱼的大脑和眼睛比水温更高。与眼肌之一相连的是一种能加热大脑的组织。这种大脑加热器富含线粒体和细胞色素c，并通过一个血管热交换器供血。它可保护中枢神经系统在剑鱼每日垂直游动期间免受快速降温影响，这种垂直游动可能使剑鱼经历很大的温度范围。
