Diaphanization of a frog - Pelophylax ridibundus crossbred INRA (RIVAN92 strain)

The tissues are made transparent by a chemical process, and specific dyes are used to highlight the skeleton.
You can see the bones through the flesh! You can even see the circulatory system!
This is mainly used for animals too small to be prepared for osteology in the conventional way, or to study ossification sequences, for example.
This is a frog species from a breeding farm.
The frog in question is Pelophylax ridibundus (strain RIVAN92), domesticated by INRA, a cross between species intended for consumption, it is not a protected species.
The flask contains no formalin, as the specimens are fixed prior to preparation.
They are then placed in these flasks filled with pure glycerine and thymol crystals, whose function is to preserve tissues and combat mold.
The animals are not killed to end up in these jars; they are often fetuses or stillborn animals, foodstuffs or animal feed, etc
