Hi Rachel

OK, a quick answer for this one - fish like electric eels and electric 
rays use specialised muscles to generate electric shocks. These stun or 
kill their prey, but as the shock is only a quick burst it is switched off 
as soon as the prey is immobilised. However, even if still alive, the prey 
would take time to recover, by which time the eel can eat it safely - the 
electricity does not remain in the prey's body as it has already 
discharged.

I hope that helps to answer your question,

Dr David Hubble, UK
