I'm pretty sure that all large animals have hearts.
I did know that, reptiles may be strange when compared to mammals, but they still share a lot of basic organs. :)
EVERY LIVING THING HAS A HEART. NO LIVING THING CAN SURVIVE WITHOUT A HEART. So yes, I knew that.
all things in the animal kingdom have hearts. although i could see both sides.
Never thought about it, but now that I did think about it, it was pretty obvious
There is no way snakes can have hearts, those hartless B****** (fatherless children), always slithering around and biting people
they are mean :'o(
