Cannibal Snail is a Predatory snail that attack other
snails or slugs and feed them as it food. According to the
Global Invasive Species Database, the rosy wolf snail is
considered one of the world’s 100 worst invaders. Cannibal
Snail can lay approximately 25 – 40 eggs a year, and the
eggs hatch after 30 days.
Cannibal Snail was introduced to Hawaii in 1955 to hunts down for African Land Snail, which lead many other snails in the age of extinction. In the Same year 616 of that snail was introduced to Oahu, only about 3 years the Cannibal Snail population already blow up, which make Human take 12,000 of it species and introduced to other island in Pacific Ocean.
Cannibal snail has cost the extinction of many species of snail and slug. According to our research 400 species of snail that extinct, 234 species of them was live on the islands that Cannibal Snail been introduced, we can conclude that more than 50% of them were ultimately caused by the Cannibal snail.
Because the action of Cannibal Snail, which cause many species of snails to extinct it can effect on our social life. One of an entertaining event can be shut down if the Cannibal Snail keep invading which is the snail racing.
Cannibal Snail has created a competition for many other animals like Hedge hogs, newts, toads and some birds, that love to eat slugs and snails. If the Cannibal Snail keep invading, it would create a difficulty for Hedgehogs, newts, toads and some birds to find a food. Whenever other species of snail and slug extinct, the Cannibal Snail will also extinct, which could cause a major harm to biodiversity. When all the Snail and Slug got extinct it would affect the food chains of other animals, Slowly other animals will be lacking in their food source which create the unbalance in biodiversity.
Because most of the snail become endanger, for the first solution is to suggest the use of Cannibal snail as a food instead of other type of snail. Once people following this solution, it can control the size of the invasion and it also help with the endanger snail to reproduce.
