  • The dentition of a carnivore and a grazing herbivore
    • Herbovore
      • Horny pad
      • Canines absent / small indistinguishable front incisors 
      • Teeth continuously growing 
      • cheek teeth large surface area for grinding. interlock, W M arrangement 
      • Teeth made for manipulation of food 
    • Carnivore
      • Small flat top incisors
      • canines, large and backward pointing, killing and holding prey 
      • Sharp cutting edges on teeth
    • how the gut region of a ruminant is adapted to its diet 
      • First three chambers in ‘stomach’ modified oesophagus- 4 chambers 
      • large volume, longer gut
      • Symbiotic / commensal bacterial mutualism
        • anaerobic conditions
      • reverse peristalsis/ regurgitate / chewing cud 
      • cellulose digestion by bacteria 
      • urea in saliva to provide nitrogen. Thick keratinized lining.           
      • Protein digestion only in true stomach, bacteria used as food source
