It looks similar to part of the cooling system on the back of my refrigerator.
Yeah. It's just random (relatively) modern piece of tubing that either fell off a boat or was tossed over board.
Cool memory for OP, and they picked up a piece of trash from the ocean.
Picking up trash under water is not the same as picking up trash on land. The small piece OP collected was probably ok, but the damage you can do to the ecosystem by removing a bottle or other big chunks that have been there for years can be really bad. I hope all divers have that in mind when they explore the underwater world.
Edit: I don't get the downvotes, I'm not making this up. It's one of the first things you learn as a CMAS diver.
I can't confirm if that's true, but that is actually oddly interesting. Maybe the downvotes because... It sounds so weird?: adding trash to water is bad, but removing trash can also be bad?
It is really a headscratcher for me too, would like to read some info about it if you can share some sources?
There's just a different "quality" of trash. Something deeply embedded in the ecosystem will become part of it. If you plug a bottle or large piece of metal from the floor you will destroy some form of habitat. Floating plastic has to go of course, as well as strings or nets.
