Bekhorot 41: Tumtum and Androgynous: Animal Edition

Beginning with a couple of mishnayot -- on a calf whose tail doesn't reach down to the upper leg joint, which is considered to be a blemish. Imagine a camel to help picture the join on the animal, which is more pronounced on the camel. Also, blemishes in a first-born that don't lead to slaughtering outside of the Temple -- with a decently long list, including, eventually, the tumtum and androgynous in the context of animals, and not people. Also, delving into the question of the tumtum with hidden genitals, where the gender is not known, as compared to an androgynous, who truly has both male and female genitals, which couldn't be slaughtered in the Temple, in the case of error. Also, note phenomena that may be treated as a blemish, but maybe it's only a physical cut, and not a real and lasting blemish. Plus, the application of the categories of tumtum and androgynous to the animals. Also, Rabbi Yishmael's opinion on this serious blemish -- in contrast to the other sages, who focus on how it isn't necessarily a blemish.
