5 Interesting Facts About Anegada Rock Iguanas

Anegada Rock Iguana

Here is an Anegada rock iguana on Moskito Island

I recently read about Sir Richard Branson’s efforts to save endangered animals on his Necker Island in the British Virgin Islands.  One of the amazing and critically endangered animals that are being saved there is the Anegada rock iguana.

Here are five interesting facts about them:

  1. These cool looking lizards grow to about 56 cm long plus their tail.
  2. They normally eat a wide range of leaves, flowers and fruit, but due to competition with introduced sheep, goats and cows, are forced to eat less healthy plants, which impacts the breeding ability of females.
  3. Anegada rock iguanas like to live in burrows and caves, and mating couples often live close together.
  4. At breeding time, females normally lay 12-16 eggs.  Not many babies survive as they are eaten by feral cats and dogs.
  5. Anegada rock iguanas are naturally found on the islands of Anegada and Guana.  They used to be found on Puerto Rico and Saint Thomas, but are extinct there now.  Due to habitat loss, introduced predators, the pet trade and competition from livestock their numbers have dropped significantly and now there are probably only about 200 left in the wild.  Thankfully, some have been introduced to Necker and Moskito Island and they are starting to breed there which is very exciting.

I hope that you found these facts interesting and learned something new.
