Euhadra peliomphala is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Bradybaenidae.
This species is endemic to Japan. The species exhibits exceptional geographical variation in its mitochondrial DNA.[1]
Subspecies
[edit]Euhadra peliomphala has 4 subspecies:
- Euhadra peliomphala kunoensis Kuroda in Masuda & Habe, 1989
- Euhadra peliomphala nimbosa (Crosse, 1868)
- Euhadra peliomphala peliomphala (Pfeiffer, 1850)
- Euhadra peliomphala simodae (Jay, 1856)
Hormonal control
[edit]As Euhadra peliomphala matures sexually, it develops a "head-wart" between the optic tentacles. The development of the "head-wart" parallels the development of the snail's reproductive system. The "head-wart" releases the steroid hormone, testosterone, throughout the body before mating.[2]
