You know what is random the fact that something the size of kangaroo gives birth to a jellybean weight and a 100 lb woman has a ten pound nightmare baby ...that my friends is random and sooooo very wrong.
This is esp for Zoobu
CONTRARY TO popular belief, not all lizards lay eggs. Some are viviparous, or give birth to live young. And when the shingle-back--also known as the stumpy lizard--delivers, it's a mother load. "Baby stumpies are very large," says biologist Suzy Munns at Adelaide University in Australia. "They're approximately 35 percent of the mother's body weight, which is very high in the animal world." In other words, if a human were to deliver as hefty a baby, "it would mean giving birth to a child the size of an average 6-year-old!"
More painful yet, unlike humans the pregnant stumpy's body doesn't expand to accommodate the developing young--baby just invades mom's body cavity (see X-rays, right). And the reptile (back-boned animal with scaly skin) can carry up to four babies at a time! Courageous?
