Commonly known as the "talking cats" due to the
noise they make when removed from the water. Confused sometimes
with the Auchenipteridae family ( Wood cats ) but they possess
a row of scutes along their sides which is characteristic
of this group.
Mostly nocturnal and very secretive and range
from the diminutive Physopyxis lyra to the large
and friendly Oxydodorus niger.
