Punga Mare [ citation needed ] is a lake in the north polar region of Titan , the planet Saturn 's largest moon. After Kraken Mare and Ligeia Mare , it is the third largest known body of liquid on Titan.[ 1] It is composed of liquid hydrocarbons (mainly methane and ethane ). Located almost adjacent to the north pole at 85.1° N, 339.7° W, it measures roughly 380 km (236 mi) across,[ 1] [ note 1] greater than the length of Lake Victoria on Earth . Its surface area is ~61,000 km2 (23,522 sq. mi).[ 2] Its namesake is Punga , in Māori mythology ancestor of sharks , rays and lizards and a son of Tangaroa , the god of the sea.[ 1]
