What is the name of the snail live in trunk of the tree?

Answer 1

Manus Island tree-snail

Papuina pulcherrima

The Manus Island tree-snail eats mainly detritus or fungi and lichens growing on the trees they live in. The snail can live in trees because water is plentiful and it is safe from being drowned, washed away during heavy rain or eaten by ground-foraging animals.

The bright green tree-snail blends with the tree leaves and shelters in humid places-on foliage or in crevices in bark. If the humidity drops it can retreat into its shell to conserve moisture.

The constant high humidity of the tropical rainforest allows breeding several times a year. Individuals have both male and female sexual parts but cannot self-fertilise. The eggs are larger and fewer in number than other species of snail because they are in a reliable environment where most young will survive.

This snail, which is highly adapted to the rainforest environment, has a restricted distribution and could easily be exterminated if its habitat is destroyed. Locals did not collect or use the snails until tourists and shell collectors came to buy them, endangering the population. Introduced carnivorous snails (such as the giant African snail Achatina fulica) brought into Papua New Guinea to control other pests quickly destroy native populations and are a threat to the tree-snail.
