Monito, Puerto Rico

Monito island is an uninhabited island located about 4.7 km (3 miles) northwest of Mona Island and about 80 km (50 miles) off the western coast of Puerto Rico. It is 0.147 sq km (0.0566 sq mi), or 36.25 acres in size and approximately rectangular in shape. Monito is one of the three small islands in the Mona Passage and part of the municipality of Mayagüez.

Monito's name is the diminutive of Mona. Like Mona, Monito has been designated an ecological reserve by the Puerto Rican government and is not permanently inhabited.

The U.S. Air Force used Monito as an aerial bombing area target after World War II, and many large impact craters and bomb fragments remain on the island.
