These strange but cute animals is that they're so unique and crazy that is actually called "Gods joke"! First they have webbed feet, lay eggs, males have VENOM SPERSE IN THIER BACK ANKLES, and they even have a bill but they are still considered a mammal!!! Second they have NO STOMACH and the females don't even have nipples THEY SWEAT MILK, so the little hatchlings just suck on the mom's fur to get milk!
