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
