头影测量法被用来检测胎儿蝙蝠的头骨生长模式，对骨骼和软骨进行差异染色。三个发育特征区分胚胎的分类群，回声定位鼻从胚胎的分类群，回声定位口：（1）基颅保留腹向颈轴，（2）喙保留在基颅轴下方，（3）外侧半规管旋转尾。前两个动作一起将胎儿的鼻腔与飞行中的成人身体的长轴对齐。第三个动作将外半规管与水平线对齐。相比之下，口腔发射分类群的头骨被构造成使得口腔与飞行中的身体长轴对齐。小翼手目蝙蝠头部姿势和头骨形状的进化受到发声需求的限制，即，超声波回声定位因此，个体发育的microchiropteran头骨已被渠道沿着两个不同的发展路径-口发射和鼻发射Baupläne。© 1995 Wiley利斯公司
Cephalometry was used to detect patterns of cranial growth in fetal bats that were stained differentially for bone and cartilage. Three developmental features distinguish embryos of taxa that echolocate nasally from embryos of taxa that echolocate orally: (1) the basicranium is retained ventral to the cervical axis, (2) the rostrum is retained below the basicranial axis, and (3) the lateral semicircular canals are rotated caudally. Together, the first two actions align the fetal nasal cavity with what will be the long axis of the adult body in flight. The third action aligns the lateral semicircular canals with the horizontal. In contrast, skulls of oral‐emitting taxa are constructed such that the oral cavity is aligned with the long axis of the body in flight. The evolution of head posture and skull form in microchiropteran bats has been constrained by the demands of vocalization, i.e., ultrasonic echolocation. Accordingly, the ontogeny of the microchiropteran skull has been canalized along two distinct developmental paths—oral‐emitting and nasal‐emitting Baupläne. © 1995 Wiley‐Liss, Inc.
