I am seeking anyone who has ever aged any of the 34 species of the
genus {Etmopterus}, or lantern sharks.  I am working on tooth
replacement rates of members of this genus.  I am interested in
determining if the tooth replacement rates of males and females are
different.  Although young members of this genus start with the same
upper jaw dentition in males and females, the male adult sharks
develop at least two more cusps in the upper jaw teeth than the
females.  I want to determine if the tooth replacement rate slows down
faster for males than females.
      If you have ever aged specimens of the deepsea lanternsharks,
{Etmopterus}, or know of any unpublished Master of Science theses or
von Bertanlaffy equations in grey literature for this genus please
contact me.  Thank you for your attention to this matter.
