Kennedy couldn’t manage it in 1961, but someone else has. According to the BBC, Giant African Land Snails have been spotted on Cuban soil, which is bad news for native molluscs in the island nation as well as numerous plants. As if that weren’t bad enough, they also pose a health risk to people. This is one invasion Cubans definitely want to stop in its tracks, and for once the CIA has absolutely nothing to do with it.
These snails have a number of characteristics that make them a formidable problem in regions where they’ve been introduced, which includes parts of Asia, Central America, and the US. For starters, they’re big. Really big. Giant African Snails typically grow up to eight inches long, and they’ve been known to get even bigger. They lay hundreds of eggs every month, with a very high hatch rate, ensuring that once a few snails make land, they can quickly spread across a region and they’re extremely difficult to stop — in part because applying molluscicide would kill other species. Also introducing predators is also problematic because all of the snail’s natural predators would be more likely to pick on smaller, vulnerable native species.
