Subspecies
editEuhadra 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
editAs 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]
