Ok today’s indestructible creature is the East African Giant Land Snail, these snails are 20cm (8in) long now that is big. These slimy, spiral-shelled monsters are among the worlds biggest land snails.
They come from East Africa, where they have plenty of natural enemies such as snakes and wild pigs, although they are now spreading to India, Europe and both North & South America where they have fewer enemies and can gobble up crops and crawl all over gardens and streets.
They are know to live for up to 10 years and lay hundreds of eggs a month, they have a hard shell are strong and big and hide from danger under the soil.
