The skins of the following are like their flesh: the skin of a man, the skin of the domestic pig — R’ Yose says: Also the skin of the wild pig — the skin of the hump of a tender camel, the skin of the head of a young calf, the skin of the hooves, the skin of the pudenda, the skin of a fetus, the skin under the fat-tail, and the skin of the hedgehog, the chameleon, the lizard, and the snail. R’ Yehudah says: The lizard is like the weasel. But any of them that was tanned, or trodden as long as required for tanning, is tahor, except for the skin of a man. R’ Yochanan ben Nuri says: The eight sheratzim have skins.
