Whalebone is formed from "whale" (from Old English *hwæl*, meaning a large marine mammal) and "bone" (from Old English *ban*, meaning the hard structure that makes up the skeleton of vertebrates). The word "whalebone" refers to the hard, flexible material derived from the baleen plates of certain whales, used historically in various products.
Think of a large marine mammal ('whale') and its hard structure ('bone') — that's why whalebone refers to the material from whales.
