The Odontodactylus scyllarus or peacock mantis shrimp is also called PMS – by me – because it can go quite crazy for no reason and then strikes with great force. 0 to 100 real quick. It’s a member of the smashing mantis shrimps. They use their smashers to break shells and can shatter glass without any problem. They have really good eyes too, seeing much more color shades than humans. Also UV.
