james_b thought with your background in sonar, you'd probably find this segment on electric fish, from this week's Quirks and Quarks fascinating.

Check it out, the segment only runs about 15 mins, and is available on mp3 (also available as a downloadable podcast)

That's pretty cool

There are several fish which do that. There's a line that runs along the sides of fish which carries a weak electrical field (not enough to be detectable by human hands) that detects changes in their environment. It's how they swim so closely in synchronized patterns in schools.

Have the best

The fascinating part is how they use it for navigation, and then when in conflict with a rival fish use their own signal to jam their opponents signal.
