One of the largest and both most beautiful and prominent invertebrates of Vietnam is the Vietnamese magnolia snail.
Magnolia snails are simultaneous hermaphrodites. During copulating they release so-called love darts made of calcium. Mucus on the dart contains a hormone that promotes sperm preservation in the female. In this way the reproductive outcome is improved.
A BEAUTIFUL SHELL
The Vietnamese magnolia snail has a large, brightly coloured and shiny shell which tragically makes it highly attractive for wildlilfe market. Thus, besides forest destruction and disturbance, over-exploitation of this microendemic species is the biggest risk.
THE IMPORTANCE OF
EX SITU- BREEDING
In Europe breeding programs already started successfully. Important information on the keeping and breeding of the species were collected. Expanding the breeding network in Europe and building up a captive breeding network in Vietnam are important steps, next to habitat protection and continued monitoring.
