Baby Sharks Birthed in Artificial Uterus

Now, I don't know nothin' 'bout birthin' no sharks, but my first thought reading this was, "Wait, sharks are fish, don't all fish lay eggs??" Well, apparently not.

I remind you, as always:


After mating, a female produces as many as 40 fertilized embryos, separated between two separate wombs. The embryos take nearly a year to fully develop, but they begin hunting long before that. After about two months, their own yolk sacs go dry. Hungry, they start eating their brothers and sisters. After the rampant in utero cannibalization, only one shark -- the biggest and strongest -- is left in each womb.

    I was all ready to belligerently dispute your assertion that sharks are fish, but Google saved me from embarrassing myself. (Damn you 4th grade biology teacher!)

    Oddly enough, it depends on the type of shark. Some sharks lay eggs, some give live birth. Weird, I know.
