==Behavior==
Most species are very rarely observed, and little is known about their behavior.<ref name="Pitman-intro" /> They are typically found in groups, possibly segregated between sexes. Some species are so uncommon, they have yet to be observed alive.<ref name="Pitman-intro" /> On the surface, they are typically very slow swimmers and do not make obvious blows. They have never been observed raising their flukes above the water. They are all very deep divers, and many feed entirely on squid.
