Giant African snails can reach up to 8 inches in length and nearly 5 inches in diameter—about the size of an average adult fist—and can live up to nine years. In a typical year, mated adults lay about 1,200 eggs.
Giant Pink Slugs- These carnivorous slugs are found only on the top of Mount Kaputar in northern New South Wales. The 20cm long slugs are believed to be relics of Gondwana, the supercontinent that joined Australia with Antarctica, S.America, Africa and Madagascar 200 million years ago. - May 30, 2013 Courtesy: National Parks and Wildlife Service
African Giant Snails...... they are known to be a pest in the Eastern parts of Africa. They can often reach length of 8 inches and are considered huge pest as they eat any vegetation they can get their slimy faces on. They lay up to 200 eggs 6 times a year with a 90% survival rate so they can quickly become infested if left uncontrolled. More so, since they found out that these guys can live up to 5-6 years, the oldest one they knew is 10 years!
