Based on von Békésy's premise that "The physical laws served as guidelines for the evolution of the structures and functions of the middle and inner ear," we aimed to understand how the unique subterranean acoustic environment, which prom...
Toward the Origin and Evolution of Unique Echiurid Excretory Organs: New Data From Females of Bonellia viridis [0.03%]

The sperm morphology of Malacobdella japonica, a symbiotic nemertean living in the clam Spisula sachalinensis, has been examined using light and electron microscopy. In this species, the structure of the elongated spermatozoon, consisting o...
Divergent Paths, Convergent Heads: Morphological Adaptation of Head Shape to Habitat Use and Diet in Snakes [0.03%]
分道扬镳，殊途同归：蛇类头骨形态适应生境与食性演化

David Hudry
Morphological convergence-where distantly related species evolve similar traits in response to shared ecological pressures-is a hallmark of adaptive evolution. In snakes, head shape is a key functional trait linked to habitat use and diet, ...
Morphometric Variability in the Calcaneus of Sheep (Ovis aries) and Goats (Capra hircus) [0.03%]
羊(Ovis aries)和山羊(Capra hircus)跟骨的形态计量学变异

Sokol Duro et al.
Distinguishing between sheep (Ovis aries) and goat (Capra hircus) calcanei is challenging due to their close taxonomic relationship and skeletal similarities, which complicates species identification in veterinary, comparative anatomy, and ...
Investigating the Morphogenesis and Replacement of Lamprey Toothlets Using Synchrotron Imaging [0.03%]

Teeth are a key innovation that underpinned the adaptive radiation of jawed vertebrates; however, their evolutionary origin must lie with the diverse tooth-like structures of living and fossil jawless vertebrates. Most previous studies have...
Morphological Evidence for a Directional Flow Mechanoreceptor in Olive-Headed Sea Snakes (Hydrophis major) [0.03%]
橄榄头海蛇(Hydrophis.major)方向性流动机械感受器的形态证据
Alizée Wagner,Chad Johnson,Myoung Hoon Ha et al.
Alizée Wagner et al.
The sense of touch (mechanoreception) in snakes is not widely appreciated despite emerging evidence of tactile specialisation among sea snakes. This is partly due to the challenges in quantifying small (< 1 mm) and numerous scale mechanorec...
