The 32 species that make up the dolphin family are closely related to whales and in fact include the animal known as the killer whale,which can grow to be 30 feet long and is famous for its aggressive hunting pods.
我想问的是family之后跟着的are closely related to whales是什么成分?有点晕,OG上的解释是说主句是the 32 species that make uo the dolphin family。谢谢啦~!
