It depends on how you want to save it. Specimens can be soaked in medicine or kept in a dry specimen box. If it is soaked with drugs, it can generally be soaked with alcohol or preserved with formaldehyde. You can kill the captured animals directly and then soak them with drugs. If it is dry, the animal remains should be dried first, and then fixed with pins and foam. After putting it in the specimen box, it is best to put a few mothballs.
How to make specimens after death?
The first step in making a specimen is to dissect, peel off the skin of the animal, and then measure the skin and the peeled corpse, which is the source of the size of the animal.
Then the skin should be reprocessed, shoveled and tanned.
At the same time, the staff also have to carve the animal's body. Older animals will use clay sculptures to make their whole bodies. So the last animal specimen we saw in the museum was actually a model inside and its skin outside. Animal specimen making pays attention to posture control and needs to restore the real action state of animals. But it is common for museums to encounter defective animal carcasses.
Because one of the sources of specimens is animals that died in the zoo, these animals may have surface defects due to rescue or injury, so the specimen maker has to hide the defects on the non-display surface and then design the posture according to the needs of the scene.
