    No modern species of whales are extinct. Some populations of whales
    are no longer in particular areas (gray whales in the North Atlantic
    for example). There are numerous prehistoric whales that are
    extinct. An entire group of ancient whales called 'Archaeocetes' went
    extinct by around 36 million years ago due to the development of the
    Antarctic Convergence when the continent of Antarctica became
    completely separated from South America and Africa. Archaeocetes were
    the transition whales from terrestrial animals to the extant (present
    in modern times) suborders of whales.

    There are several species of whales which are endangered, for
    example: blue whales, humpback whales, right whales, and others. The
    northern right whale in particular is very endangered and nearing
    extinction.

    Cheers,
