Why this rock is probably not a meteorite:

This is a great one! A fisherman from Sweden sent this photo saying that he had pulled the rock up in his net from the ocean.

A stony meteorite would never have a protrusion like this. The protrusion would have been the first thing to break off or ablate away during atmosphere entry.
  
What is it?

A pillow basalt - a rock formed when lava erupts under water.
