daf bit: Zevachim 113

On today's daf the rabbis expound upon the Flood. Did all creatures on earth die? Some say no, the fish were spared, for it says "all that were on dry land died". Some disagree but hold that Noach brought fish into the ark. Even the re'em, a giant sea animal? Its head was in the ark. No, its head was too big; its nose was in the ark. (Questions of ark integrity are not addressed.) Others say no, its horns were tied to the ark and that was sufficient to spare it.

There is a dispute about whether the flood happened in Eretz Yisrael. Reish Lakish says that even if it did, none of the dead were deposited there. Reish Lakish says the dead destined for Eretz Yisrael were deposited in Babylon, while R. Yochanan says in Shinar. Either way, both agree that Eretz Yisrael was not defiled with the corpses from the flood. (113b)
