"Why hello there, my good man!" - The Mantis Shrimp
To emphasize how hardcore these creatures are, the Mantis Shrimp are commonly placed into two different groups depending on which type of claw they have. There are "Spearers" which have spiky appendages with barbed tips, which are used to rapidly stab and break prey. The other group is called "Smashers" which have their appendages in a blunter form which gives them a more developed club that can be used to smash their victims apart like a hammer, while making their stabbing less effective as a result. But you can't win them all, right?
But despite only having a "spear" or a "club", these creatures are capable of taking on and killing much larger victims with these rudimentary weapons. They are commonly known for their unbelievable quickness in both spear and club, capable of firing a single jab/smash at the same acceleration of a .22 caliber bullet. Their lunging punch can be shot at their prey with an acceleration of nearly 335,000 ft/s^2. What does this all mean? It means that by the time you finish your first punch, this little guy would probably be starting dinner.
