What it is

The Cuban tree frog (Osteopilus septentrionalis) is an amphibian native to the Caribbean region of the Western Hemisphere. It is the largest tree frog of North America. Its wide diet and ability to thrive amongst humans has made it a highly invasive species with established colonies throughout peninsular Florida, the Hawaiian island of Oahu, and throughout the Caribbean Islands. They range in size from 3 to 5.5 in (76 to 140 mm) and vary in color from olive-brown...
