The video explores the fascinating electric eel, a knife fish found in South America, known for its ability to generate electricity. It explains the eel's bioelectric organs, composed of Electro plaques, which allow it to produce electric shocks over 500 volts to stun prey. The eel relies on water's impurities for ionic conduction to complete the circuit. Despite its powerful shocks, the eel's larger size and higher skin resistance prevent self-electrocution.
