Poecilia mexicana is a small freshwater fish from Central America. It belongs to live-bearing species and is often found in rivers, streams and sulfur springs of Mexico.
Poecilia mexicana differs from related species in its ability to live in water with high hydrogen sulfide content and in caves. It is important for nature because it controls the growth of algae and serves as food for larger fish.
Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
