The size of the caecum, a pouch connected to the junction of the small and large intestines, varies greatly among different animals due to their specific dietary needs and digestive processes.

1. Vultures: Vultures are scavengers and their diet primarily consists of carrion (dead animal carcasses). They have a highly acidic stomach that can digest meat quickly and efficiently, even neutralizing harmful bacteria and viruses present in their food. Because of this, they don't rely heavily on fermentation in the caecum to break down food. Therefore, vultures have a relatively small caecum.

2. Koalas: On the other hand, koalas are herbivores and their diet consists almost exclusively of eucalyptus leaves, which are high in fiber and toxic to most animals. To digest this, koalas have a very large caecum that allows for a long retention time of food, facilitating the breakdown of tough plant materials and detoxification of the eucalyptus compounds through microbial fermentation.

In conclusion, the size of the caecum in vultures and koalas is a reflection of their different diets and the corresponding digestive adaptations.
