The diet of a koala bear consists almost entirely of eucalyptus leaves, however they have also been known to eat the stems, flowers, and bark of the eucalyptus tree. A koala only eats the leaves of a few eucalyptus trees and is very fussy about its diet and does not like changes in its diet. Dental formula of a koala: Incisors 3/1; Incisors 1/0; Premolars 1/1; Molars 4/4. This amounts to a total number of 30 teeth. The koala has a space between its incisors and premolars to store leaves until they are ready to be processed by the premolars and molars. The molars and premolars grind the leaves into a paste. This facilitates the digestion of food. Koala teeth are highly specialized and are a key part of the digestive process. Teeth crush food particles, thereby increasing the surface area of ​​specialized digestive organs. Their incisors are relatively sharp and are used to grasp leaves from trees. The large molars are shaped to allow them to cut through leaves, preparing them for further digestion. There is a large space between the incisors and molars that allows the tongue to move the leaves around the mouth. To make the most of the energy taken in from the diet, the koala uses a reduced metabolic strategy that allows it to retain energy for long periods of time. The koala's highly specialized digestive organs have adapted to extract the necessary nutrients from a poorly balanced diet. The koala's digestive system is also adapted to detoxify poisonous chemicals found in leaves. Koalas have a special fiber-digesting organ called the caecum, which is very long (200 cm). The cecum contains millions of bacteria that destroy fiber… half the paper… squirrels, birds and worms. Dental formula and total dentition. Their molar teeth are adapted for crushing and not for cutting. Dental formula: Incisors 3/3, Canines 1/1, Premolars 4/4, Molars 2/2 = 40. Its dentition is considered heavy due to its wide, high-cusped teeth that are better suited for crushing than slicing. They still have sharp, double-edged canines. Shape and size of the teeth. Raccoons have teeth designed for grinding plants or tearing flesh. They have 4 long, sharp canine teeth that are used for tearing food and molars for chewing food. Because they eat both meat and vegetables, they have teeth that are necessary for both to be digested. The pH of a raccoon's stomach is less than or equal to 1. Most raccoons eat during the night, as they are nocturnal creatures. They eat every day and are almost always foraging and eat up to 2kg of food per day.
