Digital Variation in the Hind Legs of the Salamander Hynobius lichenatus.pdf
- Using 30 adult specimens of Hynobius lichenatus collected at Tagami-Mura, Niigata Prefecture, the variation in digital development in the hind leg was examined externally and osteologically. The fifth digit was normally developed in most specimens (52/60; left+right=60). However, the fifth digit was vestigial in a few specimens (6/60), and was not found at all in few specimens (2/60). It is conc..

Long-term Maintenance of Egg-fertilizability in Water in the Salamander Hynobius nigrescens.pdf
- Eggs in an egg sac of Hynobius nigrescens have nearly 100% fertilizability even after three hour-long immersion in water. Promptly inseminating in water seems to be extrinsic embryologically in this species.

Seasonal Changes in the Testes and Wolffian Ducts in the Salamander Hynobius retardatus.pdf
- Adult males of Hynobius retardatus were collected in the field throughout the year except winter months, and the seasonal changes in the testes, fat bodies and Wolffian ducts were examined anatomically and histologically. Slight spermiation was beginning in some specimens just before entering the breeding pond early in May. In specimens returning to land just after breeding, spermatogonial proli..

Effects of Head Shape Variation on Diet Selection in Larvae of the Salamander Hynobius retard.pdf
- Using stomach content analysis, I assessed effects of head morphology of larval salamanders (Hynobius retardatus) on the selectivity of diets in nature. Large-headed morphs of the larvae chiefly ate terrestrial invertebrates, whereas the most abundant prey item of small-headed morphs was Diptera larvae. This suggests that larvae of H. retardatus change their prey in association with the head sha..
