新热带区Bolitoglossa属的树栖蝾螈[B. rostrata，B. subpalmata，B. adspersa，B. odonelli，B. B. Plataniumactyla，B. rufescens和B. [1]的特点是掌状的，完全蹼足。脚起着粘合结构的作用，使蝾螈能够附着在光滑的表面上。皮肤上皮的扫描电子显微镜和连续切片的光学显微镜显示脚底上异常光滑的细胞表面和增加的粘液腺数量。这些特征增强了脚通过表面张力和吸力粘附的能力。它们是一组形态特征的一部分，可能是由于幼态形成而产生的。
Arboreal salamanders of the Neotropical genus Bolitoglossa [B. rostrata, B. subpalmata, B. adspersa, B. odonelli, B. platydactyla, B. rufescens and B. occidentalis] are characterized by palmate, fully webbed feet. The feet act as adhesive structures enabling the salamanders to cling to smooth surfaces. Scanning electron microscopy of skin epithelium and light microscopy of serial sections show exceptionally smooth cell surfaces and increased numbers of mucous glands on the soles of the feet. These features enhance the abilities of the feet to adhere by means of surface tension and suction. They are part of a set of morphological characteristics that may have been produced as a result of paedomorphosis.
