It’s just a sandbar.
At most beaches the sandbar is below the surface and you must tread water to see them clearly.
At popular tourist locations, a sandbar may be raised by construction workers in order to form a wave-barrier which prevents large waves from disturbing swimmers.
Too blurry to make out. Could be a breakwater or a reef. The difference in sea colour suggest to me a natural feature
It appears that there are motor vehicles parked on top of it, so it is probably a causeway that links with another island.

Looks like a reef to me, or maybe a causeway to an island.
It goes all the way down. In a straight line. I thought it was a barrier to keep the nice water from the sea.
It was me on an island but I was scared to go too deep towards there
probably reef ridge while low tide or some human made structure to break waves
looks like it. it's a way to help slow down erosion of the beach
Its a break wall, but technically, Its a barrier too.
