Buggalo

Buggalo are giant beetles or beetle-like extraterrestrials with cowskin-colored shells that can be milked like present-day cows, which had gone extinct by the 31st Century.

Leo and Inez Wong farm Buggalo at their ranch on Mars, which is one reason why they are extremely rich. Moreover, there are other Buggalo farms on Luna, with one specifically being owned by a known Hydroponic Farmer.

Origins
The origin of Buggalo is not clear, but it seems that they are from Mars, and Native Martians have domesticated them, using Buggalo as flying horses.
