    There are around 80 species of whales and dolphins, each adapted to a
    particular environments (some shallow, some deep). Their dive times
    also vary. Most of them do not dive particularly deep. The champion
    divers are beaked whales in the genus Berardius and the sperm whales.
    Time down can be longer than 90 minutes. Dolphins are not deep divers.

    Cheers,
