Assume you're in the same class as the other person who just asked mne
this question! here's what I said to her...
I'm not surprised you haven't been able to find this - this sort of
information is very obscure and you have to dig back into some very old
and not readily available sources that only us weird whale biologists
Anyway, the vertebral formula for the gray whale, based on a skeleton in
the British Museum is: C 7, D 14, L 14, Ca 21. Typically, these vary
somewhat from one individual to another.
According to an old source, "the... cervical vertebrae are quite
independent of each other as in the Rorquals, and they have the wide
lateral foramina formed by the transverse processes, which is so
conspicuous a feature of those vertebrae in Balaenoptera and Megaptera."
(Beddard 1900, cited in True 1904).
Am checking with a friend at Smithsonian to see if there is any more on
this. Hope this helps!
