It’s wild because their cells keep regenerating. The main thing that kills them is a larger alligator or food scarcity. Otherwise the just keep growing. And not so much “high” as “far.” Propel themselves up a bank twice their body length fairly easily.

Okay but they are territorial. And will give chase. And yeah, feeding is definitely a bad idea unless you wanna become the entrée. They are all-but-immortal death machines. (Unless you manage to hold their jaws shut, but I’m still not getting that close)
