Are there Boa Constrictors in the Cayman Islands? By Elaine A. Powers, Author

When I write a book set in the Bahamas, I consider whether a similar story could be applicable to the Cayman Islands. Both countries are located in the Caribbean Sea and have many similarities, but they do have differences. I wrote a book about boa constrictors endemic to the Bahamas called, Bahamian Boas: A Tabby Tale. During my research, I learned there is a second group of snakes that are also called boas – these are the Dwarf or Pygmy Boas, which are not considered to be true boa constrictors.

I decided to check to see what boas are found in the Cayman Islands, but there is only a pygmy boa, the Dwarf Boa (Tropidophis caymanensis). This is the same genus that is found in the Bahamas. So, the Cayman Islands don’t have any true boas.

Both countries have racers, which are an important predator in the island ecosystems. Both countries also have their own species of blind snakes. Unfortunately, the North American corn snake has been introduced to the islands through the pet trade. These non-native snakes have become an invasive pest.

I encourage you to read about the Bahamian Boas, as well as the native snakes in your own neighborhoods.
