Go on youtube.com and type in mantis shrimp. They have them doing battle with crabs. Cruel i think but i found a new respect for them. I had no idea they are so fast and powerful. Guess that's why they are called thumb splitters
Never had a mantis, but I know my bird wrasse makes a short meal of any invert. - he takes them and smashes them against a rock, pretty cool IMO- makes me feel good after a long hard frustrating day at work. lol
