Adopt the segmented stripping method: after making an incision in the abdomen, first separate the skin and muscles of the abdomen and back, and then cut the body from the abdomen into two sections. Then peel it off front and back respectively. This greatly simplifies the operation, especially for larger and longer animals such as snakes and lizards.

In addition, during antiseptic treatment, traditional preservatives are generally formulated with arsenic and some antiseptic drugs, such as;

Arsenic (2 parts) + alum powder (7 parts ) + camphor powder (1 part) + glycerin (a little)

However, arsenic is highly toxic and is more dangerous during operation, especially for students. Therefore, we can prepare a non-toxic preservative:

Boric acid powder (130 parts) + alum powder (7 parts) + camphor powder (60 parts) + glycerin (a little). This preservative has the antiseptic effect Larger, non-toxic, safe to operate. Suitable for crafts, specimen making, home furnishings, especially suitable for student specimen making.

When students use the above improved methods to prepare specimens, it will be easier and safer. At the same time, there are some details in the production, which we can decide according to the production of different specimens. Let’s take the production of bullfrog specimens as an example to conduct a specific analysis.

First, execute the bullfrog: air injection method and suffocation method can be used, the suffocation method is better.

The next step is to peel off. The limbs can be cut off outside the ankle bone according to the segmented peeling method, and the toe bones should be retained (the muscles on the toe bones should be removed cleanly). The head is cut off at the foramen magnum (the head muscles should be removed). In addition, the brain tissue in the cranial cavity should be removed (use iron wire to make a hook shape, extend into the cranial cavity from the foramen magnum, and smash the brain tissue out).

After peeling off, do not embalm or fill immediately. It should be soaked in 75% alcohol for 1-2 days. Because there is a lot of mucus and oil on the bullfrog's skin, it will easily become rotten in the future. Soaking in alcohol can remove fat (some amphibians and reptiles such as frogs and lizards can be treated in this way). After 1-2 days, remove from the alcohol and apply non-toxic antiseptic on the inside of the skin (see above for the recipe). Use iron wire to make a stent, put it into the body of the bullfrog and fix it, with the front end fixed at the foramen magnum (the iron wire is made into a hook shape and placed into the cranial cavity, and the cranial cavity is filled with cotton coated with preservatives, which is conducive to fixation and antisepsis). The wire supports of the limbs pass through the palms for fixation.

When filling with cotton, pay attention to filling around the bracket and wrapping the bracket in the middle. Fill and shape at the same time to make the bullfrog's natural shape. Finally, fix the bullfrog on the table and install the art eyes. An exquisite bullfrog specimen was made. It can be used for teaching and scientific research, as well as for decoration.
