Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. [64] Extensive ship surveys have led researchers to conclude that the summer feeding range of fin whales in the western North Atlantic is mainly between 41°20'N and 51°00'N, from shore seaward to the 1,000 fathoms (1,800 m) contour. Acoustic readings from passive-listening hydrophone arrays indicate a southward migration of the North Atlantic fin whale occurs in the autumn from the Labrador-Newfoundland region, south past Bermuda, and into the West Indies.

The skeleton of a whale consists of a skull, a backbone, a rib cage, and a collection of bones that are part of the flipper, but correspond closely to the bones in the human arm and hand. It is listed on Appendix II[187] as it has an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. [69], Although fin whales are certainly migratory, moving seasonally in and out of high-latitude feeding areas, the overall migration pattern is not well understood. The most common whale bone material is bone & horn. It was thought to have evolved because the whale swims on its right side when surface lunging and it sometimes circles to the right while at the surface above a prey patch.
