Yep, i was in Dr. Roy's seminar this semester, we only got one class on mantis shrimp, but we did get to see a lot of mantis shrimp in his lab. If you're going to put a mantis shrimp in your dorm room, make sure to put it somewhere dark. If it gets light in the morning around 6 your mantis is going to start digging around and punching rocks and thats not good for your sleep(first hand experience). Mine gets active around 5 am if i dont cover up his aquarium.
