Often called “the living jewel of tropical hardwood hammocks,” the Liguus tree snail is found in the United States only in tropical hardwood hammocks of extreme southern Florida and the Keys. Florida’s population of snails may have descended from snails floating over on logs from Cuba or Hispaniola. More than 50 color forms with varying whorls of pink, green, yellow, orange, and brown evolved in the isolated hammocks of Florida. Some color forms have become extinct from overcollecting and loss of habitat.
