Child of Poseidon - All Underwater Locations

Assassin’s Creed Odyssey has 42 Underwater Locations for the Child of Poseidon Trophy and Achievement. You must complete all of the underwater locations by finding the sunken treasures in them. Use your eagle to mark the underwater treasures. Be sure to clear out the location so it shows a checkmark on the map or else it won’t count.

Below is a map with all underwater locations on it as well as zoomed-in images for greater detail. It doesn’t matter in what order you do them, they are accessible as soon as you unlock the ship in Sequence 2 of the story. You can click on the images to view the full resolution version.

Thanks a lot, found a few places I had missed,

If I may make a request, please if possible, add the names of the areas/Islands next to the location names, the maps are quite low resolution.

Thanks. No 28 and 29 hadn't shown up for me. It took a bit of time for the achievement to pop up though.
