A species whose primary food source is their own young?  I'm no
biologist, but this does not strike me as a successful survival trait.
What about the predator/prey relationship, whereby the predators eat
lots of prey, the prey become scarce, the predators die off and breed
less, the prey breeds more, the predators eat more and breed more,
etc...?  Seems like one low cycle and you're in a downward spiral
towards extinction.
