    Distribution:
    Butterflyfish and elephant noses are exclusively native to Africa; knifefish live in Africa and Asia.
    The true bonytongues occur on all continents.

    Biology:
    Some bonytongue species provide parental care; butterflyfish and many elephant noses pay no attention at all to their offspring.
    In the latter cases, juveniles must fend for themselves if they are to survive into adulthood.

    Elephant Noses-"Bats" Underwater

    They are assigned to the order Osteoglossiformes. By generating a weak electrical field, elephant noses can "communicate" with each other and also explore their surroundings at night in cloudy or turbulent water-just as bats can locate objects with ultrasound.
    By the way, the world's largest freshwater fish, Arapaima gigas, is also one of the Osteoglossiformes.
