We actually have found hind legs of walking whales.

And these earliest whales, which are walking whales, have that kind of hind leg.

Perhaps they would look a bit like their other ancestor, Ambulocetus natans, whose name actually translates to " walking whale that swims."

也许它们会看起来像是它们的另一个祖先，陆行鲸，这个名字的翻译就是“会游泳的行走鲸鱼”。
