Puerto Rico identifies the Puerto Rican coqui, a small tree frog, as its national symbol. The coqui, an amphibian living in Puerto Rico's rainforests, reaches an adult size between one and two inches, making these frogs among the largest in Puerto Rico. They vary in color, ranging from brown and yellow to green, and have distinct calls, making them easily identifiable.
These frogs live throughout Puerto Rico, and although small, have a long history of respect and admiration. When identifying themselves as Puerto Rican, citizens often say "soy de aqui como el coqui." Literally translated, that means "I am as Puerto Rican as a coqui." Coquis enjoy a large and diverse population across the Puerto Rican islands. While most live in their traditional rainforest habitats, others reside in more urban areas such as gardens and parks. These small frogs also inhabit greenhouses and find shelter beneath fallen logs and large rocks. Although native to Puerto Rico, they exist in smaller populations in the United States. Coquis appear along the east coast, as far north as Massachusetts and as far south as Louisiana. While Puerto Rico considers the coqui its national symbols, it also identifies a national tree, national bird and a national flower. The ceiba classifies as the national tree, while Stripe-headed tanangers classify as the national bird and Puerto Rican hibiscus takes the title of national flower.
