Burmese pythons have become very popular in the exotic pet industry. Irresponsible pet owners and several hurricanes have introduced the Burmese python into the Everglades. These pet owners who did not realize the quick growth of their pet and the escape of several animals during the past several hurricanes have caused a serious threat to this valuable and fragile Florida ecosystem.
Reticulated pythons are the longest snakes in the world, with records over 32 feet. The word "reticulated" refers to the odd color pattern that tends to transition through three distinct phases along the length of the snake: a blotchy, Burmese-like pattern, a series of large spots in an s-like formation, and finally a diamond pattern. They eat birds and mammals including deer and goats. Reports of people being eaten by these snakes usually go unconfirmed, but rare cases occur. Reticulated pythons are hunted for skin and meat, and their numbers are diminishing.
Carpet pythons are named for the elaborate pattern that helps them blend with their surroundings. They are listed in the CITES Appendix II, meaning that further decline in their numbers may endanger the species' survival.
Amethystine python, or Scrub pythons often have a shimmery purple quality to their scales when viewed in sunlight, hence their common name. They are not classified as threatened, but continued deforestation in their native range could quickly change this.
