Thanks so much Allison, elbuzo and Nick! This will enable me to properly describe this critter to the camera club.
Thanks for the link to the video. It was positively incredible watching that mantis shrimp spear (or club) its prey. I hope you don't mind if I give the link to the folks in the camera club. Kudos to those photographers who made a video of the action!
Good to be able to describe the mantis shrimp in my image as the spearing kind.
Thanks for wishing me good luck with my presentation!
