Puerto Rico contains the administrative territorial entity Culebra
Environment
Puerto Rico consists of the main island of Puerto Rico and various smaller islands, including Vieques, Culebra, Mona, Desecheo, and Caja de Muertos. Of these five, only Culebra and Vieques are inhabited year-round. Mona, which has played a key role in maritime history, is uninhabited most of the year except for employees of the Puerto Rico Department of Natural Resources. There are many other even smaller islets, like Monito, which is near to Mona, Isla de Cabras and La Isleta de San Juan, both located on the San Juan Bay. The latter is the only inhabited islet with communities like Old San Juan and Puerta de Tierra, and connected to the main island by bridges.
