  Not my area, but I think sand, coral, shipwrecks, bottom feeding fish maybe.

  Right at the bottom is rock and sand, but there’s also huge amounts of life in the oceans, a lot of which we still do not understand or maybe haven’t even discovered yet. Every year over 2000 new marine species are registered, so there’s a lot left to explore.

  Lots of different things, sand, jellyfish, coral, … Sadly a lot of manmade products too, like plastic bags and cans. 🙁
