Anonymous said: Hi! I hope you know the #education motherfuckers tag is just goddamn awesome. Currently, though I am having some frustration as I think you wrote a post on how dogs became, well, dogs, but have been unable to find it with all my internet jujitsu. Do you have any clue what I am talking about? If so, please post a link to it. Cheers!
Hi back! I’m glad you like the posts.
But! I have written pretty much zero words on how dogs became dogs. Are you maybe thinking of a post the estimable koryos wrote at some point? That seems like something they’d write about. Good luck!
Baby brownbanded bamboo shark (Chiloscyllium punctatum) hatching. You can see how they get all folded up in their little pouches.
Normally they would just hatch out on their own, but the aquarium staff here were concerned because they couldn’t see a yolk sac anymore. No yolk sac means that the baby might starve if it was having difficulty hatching on its own.
In quite a few catshark/dogfish species, the babies hatch out with enough yolk left that they don’t have to find food for themselves for a week or two after hatching.
