The scientific collection is made up of material from numerous collection campaigns, research work, exchanges and donations that have been carried out for more than 40 years, which has allowed the accumulation of more than 250,000 specimens of amphibians, reptiles, fish and invertebrates, the latter being the bulk of the collections and those that are in a more advanced state of cataloging. The specimens of the collections, preserved in dry or alcohol, are stored in entomological boxes or in jars and/or vials, preserved in shelves and metal collection cabinets located in two specific rooms of the Zoology Department of the Faculty of Sciences.
The preserved material is taxonomically classified and, for the most part, identified to species level by specialists. It should be noted that these collections house more than a hundred Type and Paratype species and numerous endemic and rare species from various parts of the world. The abundant material from Sierra Nevada and North Africa makes these scientific collections a reference for anyone interested in the knowledge of the biodiversity of the Betic in particular and the western Mediterranean in general.
