Naoki was floating near a group of small rocks on the bottom. He grinned up at Lee when he returned, and reached out to tickle one of the rocks. It immediately revealed itself to be an octopus then did a very good job disguising itself as a venomous lionfish as it swam away. But he didn't chase it, instead turning his attention to where a dark shape swam at the edge of the light he gave off.

He pointed out the shark just in case Lee missed it.
