| 摘 要： | 对隶属鬣蜥科、沙蜥属的变色沙蜥鳞片扫描电镜下超微结构的观察，发现了类似“钉状”感受器的结构，与壁虎科和美洲鬣蜥科中的类似。感受器分布在全身各处的鳞片中，以头背部鳞片上数量众多。所有的鳞片表面结构类似，鳞片上的角皮层细胞表面平坦，没有明显的微饰物结构，除了头背部的鳞片呈多角形细胞样。考虑到干燥环境下生活的种类附着污物不是主要的问题，而主要选择是减少反光，显微皮纹特征很好的符合这一假说。

| Abstract: | Phrynocephalus versicolor belongs to Agamidae,Phrynocephalus,Kaup."spike" structure on scales of body,especially on the head was found under scanning electron microscope.These structures were much similar to the scale sensory organ founded on other Geckos and Iguanidae lizards.These organs were also measured in the experiment.Micro-ornamentation was examined on the exposed oberhautchen surface,including other part of head,dorsal,and ventral scales.All oberhautchen cells were flat and exhibited,there were no obvious surface features except occasional polygonal cell.The dirt shedding is not of key importance in animals living in desert. |
