On the interest of taxonomic collections
Most of the scientific work of our team is based on specimens deposited in taxonomic collections:
collections of specimens
collections of prepared bones and skeletons
Caudal skeleton of a mackerel
(Scomber scombrus, Scombridae).
Neurocranium of a moonfish
(Mene maculata, Menidae).

collections of tissue samples
collections of sequences
Collections also play a fundamental part for historical and patrimonial reasons, through conservation of historical specimens:
Collections also play a crucial part for scientific purposes as well. They represent large amounts of information, as well as vouchers for further works:
Preparing specimens in order to visualise skeleton elements
Soft tissues have been enzymatically hydrolyzed and hard tissues specifically stained.

DNA can be collected on specimens that have been preserved in some liquids, like ethanol. Formalin and normal alcohol denature DNA.
All these activities are regularly performed by members of the team.
Taxonomic collections are the results of former studies and also the base of future works on the biology of organisms.
