所有动物的身上都有生物电,只是有些动物带电量小,有些带电量大。而人的电流相对来说很微弱,一般情况下感觉不到。有些动物能在体外产生电流。电鳐(yao)、电鲶(nian)等会放出电流将猎物——小鱼、蟹(xie)、虾以及一些进入水里的小型哺乳动物击昏。这些鱼的体内有类似电池的器官(通常在尾部)。这 All animals have bioelectricity, but some animals with a small amount of electricity, some large amount of electricity. The human current is relatively weak, under normal circumstances do not feel. Some animals produce electricity in vitro. Electric yao, nian, etc. will release current to stun their prey - fish, crabs, shrimp and some small mammals entering the water. The body of these fish has battery-like organs (usually in the tail).
