Dolphins, at least some, can detect electricity

Interesting, BBC story here.

I knew sharks could, I will have to do some research on this and do a more detailed blog about it, in the near future.

I'm not sure if they are detecting the electrical  activity of the muscles or the change in the electrical flows in the water.  I suspect it is the latter for two reason.  First I am unaware of any land animals that have this ability.  Secondly, the electrical impulse that muscles generate is very very small.  We need electrodes attached to skin to detect that, that is what they are doing at the hospital when they check your heart.
