CL: The thing is that if sharks are excluded based on being smaller than whales, then the implication was that he considered whales to be "fish-shaped", which is a vague statement by itself...
True. Maybe he means "shaped like some particular (oddly-shaped) fish". For example (although not a good one), maybe by "fish-shaped" he means "eel-shaped", and then the answer is "anaconda" or something.

I guess you mean the pirarucu. However, although this is an air breather (i.e. it comes to the surface of the river and gulps air), it can also breathe water - this is true of all air breathing fish. So the bit in the riddle about "I cannot breathe water - only air" is incorrect.
