Yucatan Molly

The Yucatan Molly, scientifically known as Poecilia velifera, is a fish characterized by its large, sail-like dorsal fin in males and its ability to thrive in both fresh and brackish water environments. These mollies are native to the Yucatan Peninsula, specifically in coastal waters and cenotes. They are known for their distinctive appearance, with males displaying vibrant colors and a prominent dorsal fin, while females have a more muted coloration.
