I wish my ichthyology class had covered sharks more (freshwater pleb here), but I'm having a hell of a time looking this up. Anyone have any idea what the function of this anatomical feature is?
It doesn't appear to be a synapomorphy of any one shark clade, and so many sharks have it that I'd be hesitant to assume it's just a vestigial artifact of development.
