Once the meal is reduced to poop, the snake can get rid of it through an anal opening, or cloaca, which is Latin for ‘sewer. ‘ This opening can be found at the end of a snake’s belly and beginning of its tail; unsurprisingly, the feces are the same width as the snake’s body.

What is the smallest vertebrate?
frogThe world’s smallest known vertebrate is a frog the size of a housefly, a new study says.

Do humans have amniotic eggs?
The duck-billed platypus and some other mammals also lay eggs. But most mammals have evolved amniotic eggs that develop inside the mother’s womb, or uterus, and so lack a shell. In humans and other mammals, the chorion fuses with the lining of the mother’s uterus to form an organ called the placenta.
