Yesterday I saw a dead longhorned beetle at the bottom of the pool, but I didn't have time to photograph it then so I left it in there. Today I remembered it was there, and I fished it out with a net and it was pretty much as dead as dead can be - it even had "rigor mortis", making it difficult to pose for photos. As I was taking photos, however, it began to twitch and it eventually came back to life. How do insects "die" for over 24 hours and then come back to life? If cellular activity ceases and the the cells die, I think the chlorine in the pool prevents them from being broken down by microorganisms. Weird...
