Some have the remains of hind legs and a pelvis still inside their bodies.
On top of that, land was where mammals evolved.

What evidence supports the hypothesis that whales were land dwelling mammals?
they had hip bones
What evidence supports the hypothesis that whales evolved from land-dwlling mammals?
Theory of evolution
What mammals do not live on land and do not lay eggs?
Marine mammals do not live on land, and no marine mammals lay eggs. Marine mammals include whales, dolphins and porpoises.
Did whales ever walk the earth?
Not as whales, no. Marine (sea) mammals (whales, dolphins, etc.) are descended from terrestrial (land) mammals, but they're not identical with those land mammals... among the more obvious changes, they've lost their legs. The related links section has a link to a Wikipedia page showing what some of the distant ancestors of whales might have looked like.
Do all mammal live on land?
Whales and dolphins are mammals and they live in the water so no, not all mammals live on land.
What evidence supports the hypothesis that whales evolved from land-dwelling mammals?
The evidence that supports the hypothesis that whales evolved from land-dwelling mammals includes the sinonyx. This is a wolf sized mammal that is believed to be a transition between the land animal and the ocean whale.
What is a mammals environment?
Land, sea (whales) and air (bats). Deserts, forests, tundra, mountain tops - you name it - mammals are there.
Were whales always sea mammals?
No. Bset science can tell mammals were first land living. And the creatures that eventually became whales for some reason opted for a more aquatic Lifestyle.
What land mammal group is the beluga whale?
Beluga whales (Delphinapterus leucas) are aquatic mammals, not land mammals. They are cetaceans found in Arctic and Sub-Arctic waters.
Where are mammals?
The habitats of mammals are quite diverse depending on the particular species. Most of them are land mammals but there are some which are marine mammals like whales and others which are amphibious like hippos.
Do killer whales live in the ocean because they get oxygen from water?
killer whales are mammals but they can not live on land beacause they are to big and can not walk with flippers.
Why are vestigial structures considered critical evidence of evolution?
Vestigial structures are considered evidence, but no more critical than any other line of evidence in Biology and palaeontology. They're considered evidence, not because of their function, but because of the way their morphologies follow the nested hierarchies of biology: the vestigial legs of whales, for instance, have exactly the kind of shape we would have expected them to have if whales had descended from land mammals. The same goes for human tailbones and embryonic branchial ridges, the wings of emus, and so on.
