Yes, this sucker can survive on wet land for prolonged spells, crawling to the next pond or lake to resume feeding by wriggling its body and fins. It’s perhaps no surprise that this apex predator is a prime example of a dangerously invasive species that can wreak ecological havoc, spawning like wildfire and wiping out anything in its environment.”
