Abstract:
The digestive system of different organism varies because of variations in diet, habitat
and size of the animals. The major classification for animals includes herbivores, carnivores and
omnivores. This paper aimed to investigate about the length of the digestive systems of
herbivores, carnivores and omnivores and the impact of diets on the length of the digestive
system. The significance of conducting research in this area was to gain idea regarding the
different dietary patterns in the different animal groups. The research hypothesis was that animal
consuming leafy greens and vegetables will have longer digestive systems compared to those
consuming meat. The experiment was done with specimen of 2x pig, rat, squid, 2x sardine, 2x
cane toad, mullet and for each specimen dissection of the stomach was done and the digestive
system was pulled out to measures the small and large intestine. The comparison of the length of
digestive system of different animals revealed that female pigs had the longest digestive system
and sardines had the smallest digestive system. However, the validity of the research was found
to be low as exact dissection was not done. Hence, to get valid and reliable findings in the future,
it is recommended to improve the site for dissection of each animal.
Literature review:
The gastrointestinal systems of animals play multiple function of digestion,
osmoregulation and protection. Karaso and Douglas (2013) gave the evidence that the
morphology, physiology and biochemistry of the digestive system has impact of food chemistry
and types of food taken by animals. The study by Wang et al. (2003) further confirmed the above
concept by investigating about the relationship between food habits and digestive tract
morphology of six rodents. After removing the digestive tracts and measuring the length of the
stomach after stretching the stomach to full length, it was found that herbivores group had the
largest intestine compared to other omnivorous species of rodents. In case of omnivores, the
