I don't think the octopus in that video had a chance to ink, or even see more than a flash of the Mantis before it was too late. It was most likely dead/severely damaged on first contact and the Mantis just kept pounding away to make sure.shipposhack;102040 said:The difference between a mantis shrimp and a crab is the Mantis will generally be smarter, stronger, and more aggressive. An octopus has a much greater chance of being successful eating a crab than a Mantis Shrimp.
PS - That video is really sad! I was thinking of a (pretty much) full size octo and a mantis that was at most half the size of the octo. My thoughts were reversed from what it really was though. I didn't see any ink from the blue-ring, which seems weird to me. Is it noticeable when they release TTX or is it only through a bite?
