The World’s Spiny-tailed Iguanas Need Your Help!

The genus Ctenosaura has the greatest number of threatened species of iguanas — highlighted here are among the most Endangered. The contribution you make today will support conservation actions for these Central American Spiny-tailed Iguanas.

The Motagua Spiny-tailed Iguana Ctenosaura palearis (above) is restricted to the last remnants of seasonally dry tropical forest in the Motagua Valley in eastern Guatemala. They are found in several disjunct forest patches that total less than 190 square miles. Illegal hunting is a serious threat as well as the conversion of their habitat from forest to agriculture.


Roatán Spiny-tailed Iguanas, Ctenosaura oedirhina, (left) are found only on the island of Roatán, the largest of the Honduran Bay Islands. This iguana is also threatened by illegal hunting for human consumption and predation by wild-roaming domestic cats and dogs. They can adapt to a variety of habitat types, as long as they are protected from non-native predators.







The Útila Spiny-tailed Iguana, Ctenosaura bakeri, (right) is unique among spiny-tailed iguanas in that its main habitat is in the mangrove swamps.  They are endemic to the island of Útila, in the Bay Island archipelago off the Caribbean coast of Honduras. The iguanas occupy less than 3.9 square miles of the island.


By supporting the IIF, you will:

  • Help us support local efforts to implement conservation strategies for these iguanas.
  • Help us purchase suitable land for iguana safe havens — where the habitat can be restored, augmented, and protected.
  • Help us expand our outreach and education programs to instill local pride and stewardship in iguana conservation.
  • Help us provide alternative incomes through ranger guide and educator programs.
