Diaphanization of fish

Common Sar - Diplodus sargus

The aim of diaphanisation is to make the fish transparent so that the skeleton can be seen through the flesh.

The flesh is made transparent using a chemical process, and specific dyes are used to highlight the skeleton.

This is mainly used for animals that are too small to be prepared conventionally for osteology, or to study ossification sequences, for example.

The flask does not contain formalin, as the specimens are fixed prior to preparation. 

They are then kept in these flasks filled with pure glycerine, which preserves the tissues. A few crystals of thymol were also added to the preparation to combat mould.

The animals have not been killed for this purpose; the fish comes from a fishmonger's in Marseille.

Dimensions of the jar: 

Height 17.5cm with knob Diameter: 10cm

A paraffin base is poured into the bottom of the jar to hold a translucent rod, which stabilises the fish in suspension.
