Did you know about the deadly mantis shrimp, strong enough to break the shell of a crab. Another thing about these beautifully dangerous creatures. Is that they go by nicknames such as “prawn killers” (Australia) and “thumb splitters” (pretty much worldwide). Also, these magnificent creatures, are a violent killing predator. Killing their prey with a menacing slash. In the same way a mantis fish, could easily cut your finger in a millisecond. Lastly these quick and deadly predators, usually eat prey like, crustaceans such as clams, fish, or other small things.
