Summary


The skeleton of cartilaginous fishes is notoriously difficult to prepare,
and the literature dealing with the subject is extremely rare compared to
other vertebrate groups. As a result, chondrichthyan skeletal specimens held
in museums and other scientific institutions are often limited to isolated
sets of jaws, taxidermised specimens and small individuals preserved whole
in fluid. However, skeletal characters are heavily relied upon in several
taxonomical and phylogenetical analyses, highlighting the importance of
properly prepared skeletal specimens in research collections. The relevant
literature is briefly reviewed herein, with a proposal for a new and simple
protocol involving limited and easily obtainable chemicals, for the quick
preparation of clean and durable chondrichthyan skeletal specimens. Various
features of the chondrichthyan skeleton are also discussed, along with the
microstructural effects of the chemicals involved in the protocol.
