The main threats you will encounter here are Bonesharks which you will encounter in very small numbers, so they won’t be much of a threat. At this location, it is possible to find both bridge and hull fragments.
The next place is going to be the northwestern mushroom forest which you can get to by again starting from the coral tube starting point and heading just in between west and northwest on the compass until you reach the forest. You also might need to Mk1 depth module for your sea moth depending on how deep/far you explore the crag fields so keep that in mids as well. But if you aren’t, then make sure you have a stasis rifle and your sea moth is in a high enough place so they won’t attack it. So if you’re going to be searching using your sea moth, then make sure to have perimeter defense to ward them off.
The main threat you will encounter while searching through the crag fields is bone sharks, which aren’t all that difficult to deal with, but they are annoying as they will constantly attack your sea moth even while you aren’t in it.
