• Taíno legend: coquí called for rain
• "De aquí como el coquí" (From here like the coquí) = authentic Puerto Rican
• Invasive in Hawaii (1988 arrival via plants), Florida, Caribbean — ecological threat

Conservation

17 Eleutherodactylus species in PR; 3 extinct, several endangered (habitat loss, chytrid fungus, climate). E. coqui remains abundant but declining in some areas.
