Mantis Shrimp are some extremely interesting animals. They look like small, rainbow colored lobsters. Despite being small, however, they are very destructive. For one thing, they have two appendages on them, that can strike at blazing fast speed, at about 50-83 kilometers (31-52 miles) per hour. They actually strike so fast that the water around them boils. This produces bubbles, which collapse and release energy in a process called cavitation. These bubbles may seem harmless, but they are capable of destroying ship propellers, pumps, and turbines made of stainless steel. If you kept one in a tank and ended up ticking it off, well I hope you wanted to clean up some water and broken glass. They also have more than ten different color receptors, enabling them to process colors that we cannot, such as those in the infrared or ultraviolet range. Compare that to us humans, where we only have three color receptors (those receptors process red, green, and blue light, which also enables us to process colors like orange or yellow). I wonder what a rainbow would look like to a mantis shrimp. Anyways, what are some cool animals that you know about?
