In addition to the invasive Burmese pythons, the North African python is also making its presence known in South Florida, the Tampa Bay Times reports. And they’re not just staying in the swamp. Last month, a 10-foot-long rock python strangled a family’s Siberian husky; the mother of the 12-year-old and 15-year-old who saw it happen says her children are traumatized. State biologists say there’s evidence these snakes, which are have particularly nasty tempers, are breeding near Everglades National Park.
