To find the kashrus status of an organism, we first need to correctly classify it as tzomeach, animal, bird, or fish, as each group has its own distinct requirements. E.g., animals need to chew cud and have cloven hooves, while fish need (fins and) scales.

What is the halachic definition of a tzomeach (צוֹמֵחַ)?

  • @Shokhet I am not going to. I assume it would be anything not in the other three categories. Furthermore, I don't see any questionable animals, only questionable plants (e.g. slime mold), birds (e.g. dinosaurs), and fish (e.g. penguins). Each of those would be animals if not that other thing.

  • @Shokhet Besides, I don't have a single Hebrew term to ask about. ;-)
