Unique Information
Tigers rely on their sense of sight and hearing rather than on smell when hunting prey. They stalk their prey from the rear in attempt to get as close as possible to prey. Then they attempt to take down their prey with a powerful bite to the neck or throat.
Reproductive System
Bengal tigers reproduce sexually with a mate. Tigers don’t have a set season for reproduction to take place. Instead they are able to engage in the activities throughout the year. Most of the time it will occur from late November through early April. Males are ready to mate when they are 5 years of age. For females it is about 3 ½ years of age. Once conception has occurred, it will take about 16 weeks for cubs to be born. The male and female part ways after conception. So she will be on her own to take care of them during the incubation period and afterwards. She will find a den where she can go to before they are born. Generally there will be three pups born at a time. They weight about 2 pounds each. The cubs will remain in the den until they are about 8 weeks old. The males try to kill these young cubs if they come into contact with them. This is because the female will then be able to mate again with him.
Digestive System
Bengal tigers have a very similar digestive system to all mammals. They have an esophagus, stomach, colon, large intestine and small intestine. The digestion starts in the mouth and then in the stomach. The churned food is then processed into the intestines and then excreted out of the body as waste.
Respitory/Circulatory System
Bengal tigers have a cardiovascular system. In a cardiovascular system the heart pumps blood into veins and arteries throughout the body. This blood is oxygenated which is helps these tigers breathe. They get their oxygen by either inhaling through their nose or mouth. It goes into their lungs. They exhale out carbon dioxide.
Nervous System
Bengal tigers have a nervous sysyem like most mammals. They have a central nervous system which contains a brain, spinal cord and vertebrae. The vertebrae protects the spinal cord and it's very important for the tigers survival.
