Scientists to Breed 'Test Tube' Sharks

Messing with nature here... And as much as I love sharks, if they naturally have only the strongest two in a litter (right word?) survive, that's how it was meant to be. Just because a group of scientists somewhere they should suddenly change how their breed of shark works, doesn't mean it's what should be going down.

Also, I thought that nurse sharks were a breed that was easier to keep in captivity then a lot of others because you rarely see an aquarium without a few in it. (Vs. great whites, who produce offspring at an even "less productive" - oooooh, bad pun- rate and have never survived in captivity.)
