Most sharks can't swim backwards. I would also assume many larger, fast moving fish such as tuna and mackerel probably can't either.

I believe most species of catfish can't swim backwards... I know they can kind of 'jump' to get their momentum moving rearward, but I don't know that they can actually 'swim' backwards... Hmm.
