The Tabernacle was made up of several layers of different types of materials, one of which was made from an animal called a taĥash.  The identity of the taĥash is a matter of great controversy and was never resolved. Prof. Yehuda Feliks, one of the foremost scholars in the field of nature in the Bible, suggests that the taĥash may have been a giraffe (seen above), which has many of the characteristics mentioned by Rabbi Meir: A multicolored hide, a horn-like protrusion on its forehead, and some of the signs that determine that an animal is kosher.
