I'm new to the forum but I had a mantis show up 10 years ago after 10 fish disappeared one by one over a month. I had to remove all the live rock to get him out of the tank. Got interested in them after that and read a lot. I believe I have read that the mantis shrimp has 21, and later in another read 23 types of sensors in their eyes. Like we have rods to see black and white and cones to see color the mantis have at least 21 types in their eyes. They see way into the infrared and ultraviolet and who knows what else. I also believe they use these to identify their mates in the deep darkness. Am I remembering that all right?
