It contains one species, Ambulocetus natans (Latin natans "swimming"), known solely from a near-complete skeleton.
Retaining large hindlimbs, it was once thought that they could walk on land—indeed, their name means "walking whales"—, but recent research suggests they may have been fully aquatic like modern cetaceans, though the research has some limits that cast doubt on this conclusion.

Baleen (the long keratin strips that hang from the top of whales' mouths) was used by manufacturers in the United States and Europe to make varied consumer goods.
