TLDR- Very big boats. These cables are around the thickness of a garden hose supposedly, but are massively armored. If you look at the submarine cable map, there are hundreds of links between places, so if something goes wrong it’s easy to go out and fix a section either with underwater divers or by pulling a section up to the surface and repairing it.

They are also *very* expensive, $2-6 million *per kilometer* of cable. Animals don’t think much of them, and usually stuff will start growing on it.
