An octopus' life is short — two years is a pretty common lifespan — and heavily focused on reproduction. They only get one shot at carrying on the genetic lineage and die soon after breeding. Babies are born not by the two, or tens, or even hundreds. Instead, tens of thousands of octopus siblings enter the world all at once — tiny, translucent hatchlings that ride the waves and try not to die more quickly than they already must.
This footage of an brood of giant Pacific octopuses hatching was filmed by divers in Puget Sound just a couple of weeks ago.

This is one of those news stories where my biases show, like woah, and I'm happy to admit it. In the UK, 50% of laboring women take advantage of nitrous oxide (good ol' dentist's office laughing gas) for pain relief. The rates of usage are about the same in Canada and even higher in countries like Finland. If you read up on the stuff, this isn't terribly surprising. Nitrous oxide gas doesn't totally eliminate childbirth pain, but studies show it does a great job of taking the edge off and without the long-term loopiness of injected narcotics or the limitations on movement (and the whole needle-in-your-spine bit) that goes along with epidurals. Plus, it's pain relief that's controlled by the woman, herself. You just take a hit off the gas whenever you find your contraction warrants it. No anesthesiologist necessary.
I'm due to give birth in less than two months and this is something I'd love to use. But I can't. Because there are only two hospitals in the entire United States that offer it as an option. They're both on the West Coast. (NOTE: Reader djmburr says his wife was able to use nitrous oxide at Baptist Hospital in Nashville earlier this year. So it sounds like there are more hospitals allowing this than making it into the news.) Read the rest
This baby nautilus emerged this week from an egg laid last November at San Diego's Birch Aquarium. For this tiny cephalopod, the process of being born took not hours, or even days, but weeks. The ZooBorns site has a series of photos that show how the nautilus slooooooowly emerged from the egg. Read the rest
I'm reading a ton of baby and pregnancy books right now, preparing both for the October birth of my daughter and an upcoming BoingBoing feature about evidence-based books for science-minded soon-to-be-parents. After reading this interview at The New Inquiry
, I really want to check out The Motherhood Archives
— a documentary about the ways culture shapes and reshapes how we understand the biology of birth and the growth of an infant. From the Marxist origins of Lamaze, to the early-20th-century feminists who pushed for pain-free birth, to the rise of the birth center, The Motherhood Archives
sounds like a fascinating exploration of how different generations think and rethink the same ideas and an anthropological assessment of what "the right way" to give birth and raise children really means. (Thanks, Emile Snyder!) Read the rest
A preggo info site that contains links to Cochrane Reviews, an evidence-based maternity care report, and evidence-based resource links for you and your doctor? Um, yes please

"Born in the caul" is a phrase that's connected with a lot of cross-cultural myths and superstitions — babies born in the caul are supposed to be destined for lives of fame and fortune (or, possibly, misfortune and grisly death, depending on which legends you're listening to). Biologically, though, it refers to a baby that's born with part of the amniotic sac — the bubble of fluid a fetus grows in inside the uterus — still attached. Usually, a piece of the sac is draped over the baby's head or face. These are called caul births, and they're rare. But, about once in every 80,000 births, you'll get something truly extraordinary — "en-caul", a baby born inside a completely intact amniotic sac, fluid and all.
There's a photo of a recent en-caul birth making the rounds online. The photo is being attributed to Greek obstetrician Aris Tsigris. It's fascinating. But it's also pretty graphic, so fair warning on that. (If the sight of newborn infants and blood gives you the vapors, you might also want to avoid most of the links in this post, as well.)

My dad calls the first few months of a baby's life "the necessary larval stage". I've heard other people refer to it as "the fourth trimester". Basically, newborn human babies are pretty useless, as far as baby animals go
. This is especially true in comparison to baby apes, who come out of the womb at a much higher level of development. Scientific American has an excerpt from an upcoming book by Chip Walter that talks about this fact and its connection to two key moments in human evolution — the development of bigger brains (and thus, bigger heads) and walking upright (which has the side effect of creating a narrower birth canal).

There is definitely a seasonality to human births, writes Beth Skwarecki at Double X Science. The complicated bit is that human baby season isn't necessarily the same (or as strongly expressed) from place to place and culture to culture. In the United States, significantly more babies are born in July, August, and September. Meanwhile, in Europe, babies seem to make their way into the world in spring. So there's clearly a cultural component to this — but culture doesn't explain it, entirely. Skwarecki's piece explores a messy place where culture, genetics, and circadian rhythms intersect

So. That happened.
Interesting tidbit for those of you too horrified to watch: Hissing cockroaches apparently give birth upside down with their lady parts up in the air.
Another thing I learned: Animals giving birth is apparently a fairly popular YouTube genre. Check out the sidebar for cats, snakes, and more cockroaches.
A hearty thanks to Amos Zeeberg, without whom I would never have seen this horrible thing.
