Target Mantis Performs 7-Minute Defensive Dance

This is a video of a spiny flower mantis (Pseudocreobotra wahlbergi, aka the target mantis due to the large eyespots on its forewings) performing a 7-minute defensive dance to let a presumed threat (in this case the cameraman) know that it will fight you, and it will tear you limb-from-limb if it has to. Not a bad technique, but if I had to perform a 7-minute dance every time I felt personally threatened my life would be the world’s saddest 24-hour dance party.
