ABOUT

Though the colorful shells of giant mantis shrimp are beautiful to behold, the sight of one often means death. These apex predators resemble brightly colored lobsters with oversized pincers. They prowl tide pools and coastal shallows, competing for territory with sharks, eels, and giant. Their pincer strike is so fast it creates light, heat, and a stunning shockwave, and its multifaceted eyes can see into impossible spectrums that allow them to easily spot creatures trying to hide with camouflage. A typical giant mantis shrimp grows to 4 feet high and 6 feet long and weighs around 200 pounds.

Reefhammer. Incredibly rare, these gigantic mantis shrimp prowl the seafloor and vast reefs, devouring everything in their path and sometimes shattering entire reefs just to pick through the ruins for prey hiding within.
