Subj line may be a bit f(lip). It's early, and I'm trying to wake up to go to farmers' market.
http://www.aces.edu/pubs/docs/U/UNP-0007/ "Certain species of animals also graze differently because of their mouth size, lip anatomy, and method of prehension (Matches, 1992). Sheep and goats have a partially lifted upper lip that is very mobile and permits closer defoliation. Cattle have a fixed upper lip that is relatively immobile (Church, 1979)." This summer, I'll go out and watch my sheep grazing. My impression has always been that they don't use their lips to help them graze, they can move their lips out of the way to more effectively use their front teeth.

She's one of 'the' authorities about sheep and goat medicine in the US if not the world. http://books.google.com/books?id=nWCLpQFrdnMC&pg=PA276&lpg=PA276&dq=sheep+anatomy+lip+&source=web&ots=XU4KPVMXM7&sig=i-YSfnSgydjppHG7CWzy6HrGuQQ&hl=en Can't copy the excerpt of this book, "Goat Medicine". But it says the upper lip of the goat lacks the dividing philtrum of the sheep. The philtrum of the sheep favors grazing grasses close to the ground. It doesn't say the lip is cleft. From dictionary.com Philtrum - Anatomy. the vertical groove on the surface of the upper lip, below the septum of the nose. Mary
