What are the Methods for Preserving Animal Specimens?

 We all know that animal specimens are made from the carcass of dead animals. So, what are the methods for preserving animal specimens?

I. Immersion Preservation

Immersion preservation involves immersing the entire animal in a preservation solution to maintain its original appearance and internal structure.

II. Skeletal Preservation

For studying the skeletal structure of animals, skeletal preservation can be used. After removing the flesh, corroding, defatting, and bleaching, the animal is reassembled in its original position to form a whole, facilitating future observation and research.

III. Taxonomic Preservation

Taboonomic preservation involves removing the animal's skin along with its hair, scales, and other derivatives to create a specimen. This method is suitable for most vertebrates, especially birds and mammals, and is widely used in zoological teaching and research.

IV. Animal Specimen Drying Preservation

Animal specimen drying preservation is generally applied to small animals or insects with low water content. The process involves removing internal organs, temporary preservation, softening, pinning, repositioning, drying, and preservation.

V. Animal Specimen Platyping Preservation

Animal platyping preservation involves hardening the animal's remains through processes such as sturdiness, dehydration, forced gelatinization, and hardening, thus preserving the animal's shape from its life. Because platyped specimens contain no water, they can be preserved for a long period.
