Most domestic animals have limited color vision. Colors are a blend of these 3 pigment being stimulated - like mixing colors. If you tried to catch 50,000 broilers in a chicken house when it is light you would probably hurt or kill the majority of them. Makes it tough to read a stop light. Carnivores have more binocular vision - need to see where dinner is at in order to catch.
Herbivores have more peripheral vision - seeing with only one eye a good part of the time.
Need to detect movement around them in order to keep form being eaten. The sound waves initiates a vibration on the tympanic membrane which initiates movement in 3 bones which are hinged together the malleus, incus and stapes . The stapes rest against the oval window and the movement of the tympanic membrane is amplified. As the vibrations move down cochlea the wave will eventually be dissipated at the round window at the end of the scala tympani. Sound waves move the tectorial membrane which are sensed by hair cells in the Organ of Corti which is located in the cochlear duct, bending of hair cells result in opening of ion channels and depolarization.
