The Coquí is a small tree frog native to Puerto Rico. It is known for its distinctive, high-pitched call, which sounds like its name, "co-kee." This frog typically measures about one inch in length and has a brown or greenish color that helps it blend into its surroundings. The Coquí plays an important role in its ecosystem by controlling insect populations. Coquís are primarily nocturnal and are most active at night. They thrive in humid environments, often found in forests and gardens. The Coquí is also culturally significant in Puerto Rican folklore, symbolizing the island's natural beauty and biodiversity.
