How did the giant east African snail get to Caribbean?

The giant East African snail, or Achatina fulica, was introduced to the Caribbean primarily through the pet trade and agricultural practices. In the mid-20th century, it was brought to various islands for use in agriculture and as a novelty pet. Unfortunately, some snails escaped or were intentionally released into the wild, leading to their establishment as an invasive species in the region. Their rapid reproduction and adaptability have caused significant ecological and agricultural challenges in the Caribbean.
