Marine creatures and bioluminescence

Going in a manned submersible is definitely on my bucket list. My mother has made me promise not to tell her about it until I'm on dry land again. I've been obsessed with the idea, and with bioluminesce since I first witnessed many of these creatures over a decade ago. It is true what she says, that it's addictive. You have to order the scientists out of the lab and remind them they need to sleep in order to be awake for their next shift.

The communication aspect is something I'd like to capture.
