Some creatures use electricity and vibrations in sex (and this can be dangerous)

Most animals use touch, smell, hearing, taste and sight to identify and attract a mate (that goes for humans too).


This study confirms that other species suffer from one of the same sexual problems we’ve seen in our own species; male efforts to hook up can be harmful, even lethal.

GR:  Hmm, so sex came long after sentience.  After 385 million years we still haven’t advanced to sapience.  Is that sad, or what?
