  • Beschreibung: Age determinations based on periosteal growth lines have been compared with body weight and with the lengths of the body, hind foot, and tooth rows in 67 hedgehogs collected in southern Finland in 1960 — 1961. None of these dimensions can be used in place of growth lines as a measure of age; even in their first autumn some yearlings reach nearly the same size as older animals. In the present collection the number of animals decreased from their fourth winter. The oldest specimen was killed during its seventh winter.
