All hippos are utterly dependent on water,but in Botswana, hippos face an unparalleled challenge as deep floodwaters dry to dust in a matter of months. This documentary goes beneath the surface to show how hippos protect their families and face their enemies, revealing an animal that is highly sensitive and surprisingly intelligent.This is the life of the hippo as never seen before.
VIDEO USAGE RIGHTS
Why the AV version? Because it provides additional usage options for PBS videos. AV versions come with limited performance rights so they can be shown in classrooms, at PTA meetings, during after school programs, and transmitted on a closed-circuit system within a building or on a single campus. They also can be enjoyed in admission-free public screenings, which also makes them ideal for use by library patrons and businesses involved in community clubs and organizations.
