I need help identifying this Rock/Mineral? ?
so my brother reeled this thing in while out at sea. this is what i've observed;
1. its's shinny when you shine light at it.
2. don't have a scale, but compared to a 10 LB dumbbell... i want to say about 3~4 LB? i've picked up a chunk of metal the same size and it's wayyy heavier.
3. magnet won't attach to it.
4. to me it looks like someone just got a torch and did a bad job at cutting a piece of metal. if you've ever used or seen someone used a torch to cut metals, you'll see those tiny little balls of metal roll around. and i can see those tiny balls stuck to some areas of the "thing".
5. i can see some spots with color change, like when you heat a metal up and it turns that weird rainbow color.
6. one of the picture is zoomed in and got me puzzled. it shows what appears to be strands/ fibers? looks kind of like fiberglass.
.... i guess i can't upload anymore pictures :/....

Possibly botryoidal hematite, from your description.
Although an iron ore, it is only very feebly magnetic and a normal magnet wouldn't be attracted to it strongly enough for you to notice.
BWMC is probably correct about the off-white "fibers"; tubeworms??.

It looks like a chunk of iron or steel, or maybe lead, that has had tube organisms use it as a platform to attach to. It might be natural, and there is some sort of fibrous or acicular (needle-like) crystal structure on the surface, but from here, at this level of detail, I would favor a chunk of metal.
