Megalobulimus oblongus, also known as the Giant South American Snail, is a large terrestrial gastropod native to South America and parts of the Caribbean.
 
Belonging to the family Strophocheilidae, this air-breathing land snail is found in countries such as Brazil, Uruguay, Venezuela, Peru, and Barbados. Its shell can reach lengths of 7–11 cm, with a distinctive pink lip and a characteristic bulge on the second-largest whorl. The snail’s body is gelatinous and blue-grey with cream-colored foot and brownish tubercles, and it produces relatively little mucus compared to African giant snails. Known for its slow movement and large mouth with frond-like structures used for sensing food
