Today's diving is what we call "muck diving," which means searching for creatures (usually small ones), often amongst rubble, sand, or detritus. In fact, some of the best substrate for muck diving is human flotsam, such as bottles, discarded clothing, and such.
We have already seen, after only two dives, some very cool stuff. One highlight is that we've found several pairs of small cuttlefish, and have observed them both eating and mating. Wow! I'd only seem that on video before. We've also encountered more stonefish than I've probably ever observed before. Stonefish are very hard to see, as they blend in with their surroundings. But they pack a punch: very toxic spines that can kill humans. So it's good to know there are a lot of them around, if only to make us really, really careful.
