These fish are just plain wierd! The following sites have some great
photos as well as various tidbits of information about these large,
strange fish. As for your questions, they are widely distributed; they
get up to 3000 lbs. (or more?); they eat mainly jellyfish; and they are
eaten at times by sea lions (and other large predators?). 

As with a rudder, if they get stuck on your boat (even a very large
ship) they can slow it down substantially. See the story in the last
link about the large cement carrier whose speed was slowed from 14 knots
to 11 knots when a sunfish got stuck on its bulbous bow. This obviously
could not be explained by its effect on wetted surface area. :-) 

Great photos:

What a cool fish!
