Abstract: ? The integument samples from the 28 adult hedgehogs ( Erinaceus europaeus )(♀16,♂12) were studied by the method of anatomy. There are rich and thick subcutaneous fat and developed integumental muscle in the hedgehog in teguments. The weight of the integument of the hedgehog is about 38.02% of the body weight for male and 44.29% for female respectively. The weight of the subcutaneous fat is 6.88% of the body weight for male and 12.04% for female, respectively. There are significant differences for the weight of the integument and subcutaneous fat between males and females ( P <0 05 or 0.01), there are no significant differences for the weight of the integumental muscle and spiny hair between males and females. Except the face, the four limbs and the abdomen, there are full of the thick and stiff spiny hairs on the skin of the hedgehog. The length of the spiny hair is 16.36±1.30mm, and its diameter is 0.95±0.15mm, its weight is 3 55±0 43mg. There are 5434±475 spiny hairs in the skin of the hedgehog. According to the colour, the spiny hairs are divided into five types which are distributed in different ration in each hedgeog. There are five pairs of mammary glands in the hedgehog. There are five toes on each foot, there is a claw at the end of each toe. The peculiar structure of the hedgehog integument is very useful for hedgehog's physiological protection.
