ABSTRACT



In Poland most often meet tortoises are Horsfield’s (Testudo horsfieldi) and Hermann’s tortoises (T. hermanni). Each of this species during winter and summer hibernate. On areas with very long winter, Horsfield’s tortoise is active only about three months a year. The most interesting is tortoise alimentary canal, because they are herbivorous. The one from more interesting organs of alimentary canal is the liver, which is the energy centre of the organism. The type of food influences on the shape and size of the tortoise liver. The aim of the study was examined the structure, shape, position and vascularity of the discussed organ.

In the investigation were used 19 Horsfield’s tortoises (11 females, 8 males) and 19 Hermann’s tortoises (5 females and 14 males). For the morphometrical study were used 15 individuals from every species, remaining (4 individuals of Horsfield’s tortoise and 4 individuals of Hermann’s tortoise) were used to made injection – corrosive preparations.

Livers both of species had very precise defined position with relation to the plastron and carapax. The liver mass of Horsfield’s tortoise was greater than liver mass of Hermann’s tortoise, what caused by difficult conditions in which it lived.

Key words: tortoise, liver, mass, asymmetry coefficient, morphometry, anatomy, topography.
