They are still armored cables wrapped in galvanized steel wires though. Also the spans in shallower waters generally have two layers of steel wire. See: https:

No cable is going to be a match for a ship's anchor dropping on it or a fishing trawler dragging it but saying cutting through them is "not difficult" is not correct. You couldn't cut through them with a pair of wire cutters. They are also powered spans with 10 kV DC at both ends. So it could also potentially kill you. Anchors and trawling nets are by far the most common reasons for cable faults. Sharks chewing through them however is not common. Although it's certainly a more entertaining image.
