.... I rember reading in one of my books, that rattle snake's fetus's show "primitve signs of placentas." So this is why I started a new thread.. My question is am I imagining this? Has any one here studied this more throughly? If this is true I think it would be another remarkable observation of the evolution of Crotalida.. This is one of the main reasons why I am so enchanted by these animals so much, they are truely unique to them selves... Not to mention, that it would make rattle snakes one of the only herps that has a different level of "live birth"
