Skinks. They burrow. Arms are in the way.
Funny thing about cetaceans, many of them retain their lower limbs in some state through adulthood, and also have parts and pieces of their pelvis.
To explain, cetaceans are whales, dolphins, porpoises. To the best of my knowledge, its still a general consensus that they were former land mammals that evolved for life back into the sea, hence they have their walking land mammal bone structures.
