Massive alligator lurks at bottom of Florida swimming pool, see the mind-blowing “death roll”:

A 7 to 8-foot female gator lurks at the bottom of a Florida swimming pool. At first, the gator remained still, but as soon as members of the Florida Fish and Wildlife crew hooked a wire around its neck, it began wildly thrashing. As they pulled it closer to a set of stairs in shallow water, the gator launched into a “death roll,” an offensive move used to drown prey. This is the kind of “death roll” that would blow your mind.
During mating season in Florida, these creatures, especially the females, are on the move looking for areas to lay eggs.
