    >what fish can hold their breath longest under water with lungs?

    That is a trick question to be sure. Fish do not have lungs! (And
    they do not 'hold their breath.')

    If the question were changed to "what marine mammal can hold . . ."
    you'd be considering the elephant seal (especially the southern
    elephant seal), and the beaked whales in the genus Berardius. Sperm
    whales are good at it too.

    Cheers,
