Went snorkling in Key West. While over a sandy/grassy area I met eye to eye with some mantis. The first looked like a washed out peacock colored mantis whose coloration was a great form of camouflage on the sun dappled sandy bottom. You could sense the intelligence looking back at you. POWERFUL! The other mantis was spotted also in shallow water next to a deep drop off. This mantis was electic chartreuse in color and perfectly matched the local macro algae. Very interesting to see them out hunting in the daylight. They appeared very comfortable and relaxed. Both were sighted in less than 18 inches of water.
