Why Don't Electric Eels Shock Themselves?

TL;DR

Electric eels generate high voltage shocks to paralyze prey, using unique cells and insulation to prevent self-harm.

Hi, I’m Leo. I usually spend my time over  on the Brazilian version of MinuteEarth   –MinutoDaTerra– but today I’ve come over  here to tell you about my obsession with   one particular animal from my homeland –the  electric eel– or, as we call it in Portuguese,   “Poraque” meaning the one who puts you to sleep. An electric eel can deliver a shock o... Read More

Questions & Answers

Q: How does an electric eel generate high voltage shocks?

Electric eels possess specialized cells known as electrocytes, whose sole purpose is to generate electricity. These electrocytes make up 80% of an eel's body, creating a battery-like system that produces several hundred volts.

Q: Why don't electric eels get harmed by their own shocks?

The high electrical resistance of an eel's body compared to water ensures that most of the electric current passes through the water, minimizing self-harm. Additionally, vital organs are insulated from the current by fat layers.

Q: How do electric eels use their shocks to capture prey?

The electric current emitted by an eel interferes with an animal's internal electrical circuitry, triggering muscle contractions that can paralyze the prey. This allows the eel to either feed on or escape from the immobilized animal.

Q: How has Leo contributed to science communication?

Leo has played a significant role in translating MinuteEarth videos into Portuguese and other languages, making science communication accessible to a wider audience. His efforts have helped MinutoDaTerra gain a million subscribers.

Summary & Key Takeaways

• Electric eels in Brazil deliver powerful shocks, yet remain unharmed.

• Eels have specialized electrocytes producing high voltage electricity.

• Self-protection mechanisms involve high electrical resistance in their bodies and strategic organ placement.
