The biological experiment tells us how to do the anatomical process and peeling steps of bullfrog in the experimental class. Be more specific, don't copy.
Peeling? You can tear it directly, it's easy to tear it off, and it can't be completely peeled off at your feet. Try to cut it off. Actually, it depends on how complete your skin is. If you die from mashing, just peel it off from head to toe. Anyway, the middle is rotten. In other words, I have done so many bullfrog experiments that I have never peeled them.
