body of water in cave

I’ve seen them pictured online, but experiencing the glow worms in person was phenomenal. The way they scattered the walls, very much alive and wiggling. I learned they’re not actually worms, but larvae that feed for 9 months, then live as adults for 2-3 days. That’s just enough time to mate, lay eggs, and die. An unfortunate life in my opinion, but man are they beautiful.
