The mantis shrimp is an amazing animal. I highly recommend you buy some mantis shrimp yarn and then google the animal while you wait for your yarn to arrive. Two facts about the shrimp to intrigue you - they are very strong and can punch their prey with the force of a .22 caliber bullet. They also have 16 types of color receptive cones (we have 3, red, blue, and green) which allows them to see colors we haven't even dreamed of. Think about the yarn colors I could create if I had 16 types of color receptors! Anyway, buy this yarn and google mantis shrimp. You won't be sorry.
