The study was conducted on 40 long-tailed chinchillas (Chinchilla lanigera) (20 females and 20 males). The study measured the length of the internal organs of the digestive system and the measurements of their mass. In order to compare the examined metric traits in the male and the female, the figures were statistically analysed. The results found that the average length of the esophagus, the greater curvature of the stomach and cecum were larger in males. After estimating the mass of internal organs it was found that in the male greater value reached mass of the stomach and duodenum with food contained in it and mass of duodenum cleared of leftover food. Research has also shown that the females were characterized by longer intestines than males. The ratio of the small intestine to the large intestine in females was 1: 1.52, in males 1: 1.58.
