Herbivory: The Wild Rabbit's DietWild rabbits eat grass, wildflowers, weeds, and agricultural and garden crops. In winter their diet changes slightly, switching to shoots, twigs, bark, conifer needles, etc. Rabbits, like hares, tend to re-ingest their feces to digest it further. This process is called "coprophagia". (Washington Department of Fish & Wildlife, 2014) Feeding habits The rabbit feeds frequently, up to 30 times a day, with 2-8 g of food for periods of 4-6 minutes. (Johnson-Delaney, 2006) The amounts rabbits need depend on their age, lifestyle and general health. Rabbits become overweight and can suffer if they eat more food than necessary. (RSPCA, 2014) Rabbit teeth and dental formula Rabbits' teeth grow continuously and therefore require wear. They can be kept at the correct length/shape by eating grass/hay/green leafy plants. Not following the right diet causes dental disease. (RSPCA, 2014) Shape and size of teeth Rabbits have incisor and 'cheek' teeth. Their incisors (at the front of the mouth) are even, curved and relatively large. Their control teeth have deep grooves on the sides, and the width of the upper and lower control teeth are not equal. The cheek teeth are relatively small and are used for crushing and grinding leaves, twigs, etc. (Kressin, n.d.) Rabbits do not eat meat and therefore do not have canine teeth. Length and Complexity of the Digestive SystemThe rabbit's digestive tract is approximately 4.5 to 5 m in length. (Johnson-Delaney, 2006)It is a highly complex structure that processes and digests food, largely with the help of bacteria. (Wilson, 2010) Rabbits have a specialized digestive system suited to their high-fiber diet. As food passes through their digestive system, enzymes break down the food so... middle of paper... if there is a loss of bamboo in their area, they also experience a loss of habitat which is a threat to the their survival. (World Wide Fund For Nature, n.d.) (Travel China Guide, 2014) Giant pandas occasionally eat meat, like small rodents, despite having adapted to a mostly vegetarian diet and being fairly inexperienced predators. This could be the reason to prefer bamboo as it is easily available all year round. (How Stuff Works, Inc, 2014) Teeth Length and Digestive System Complexity Because the panda has a carnivore-like digestive system, much of the plant matter that is eaten is excreted as waste. (Smithsonian Institution, n.d.) The panda's digestive system has partially adapted to digest bamboo. They have a hard lining in the throat, esophagus and stomach, as well as an enlarged surface in the colon. (Lopez, n.d.)
