Summary: Positive correlation between the quantity of eggs in clutch of the grass snake and their diameter as well as negative correlation between quantity of eggs and their length and between the diameter of eggs and their length was revealed. It was determined that the more the quantity of eggs in the clutch, the more they are rounded, that was explained by their deformation in accumulating in the oviduct. © Petrozavodsk State University |
