Let me use the proper format this time around.
Playing on PS4, version 2033, issue mentioned in topic title.
When on an island, the music that plays when a shark has it’s eyes on you can continue the play. Then when going in very shallow water, not even knee deep, the shark can grab you from under the land and drag you down. This has happened to me twice.
On the first occasion, I got dragged around in the shallows and upon being released I got placed on land. (Sand bank)
The second time is the current topic, this is when the shark dragged me into the ocean. I’d say about as far as the area where sharks normally swim around islands
Specifically the island SW of the starting island.
No custom island were added into the world, and the world was randomly generated at the start of my playthrough.
Hope this helps!
