"So this tadpole walks into a bar, sees a potentially really hot looking
female gastrulatic blastulae and says 'Hey sweet pore... Nice dorsal
blastophoral lip you got brewing there. Your vernal pool, or mine?'"

But back to something more serious... Now I'm really interested in the
implications here since we don't typically feed entire foodwebs in our
aquaria, much else, the potential for limiting certain *necessary* nutrients
in the animal's diets. I'm going to step away from this for the moment,
however, as this is 100% "pure distraction material (tm)" from what I should
accomplish today :)
