Which four parts of the body of the fish clan are likened to different places or to objects in nature

From the text:

They say that our cheekbones are cut from those granite ridges that rise above our homeland. They say that the deep brown of our eyes seeped out of the fecund earth that surrounds the lakes and marshes. The Old Ones say that our long straight hair comes from the waving grasses that thatch the edges of bays. Our feet and hands are broad and flat and strong, like the paws of a bear.
