I think this is a repeat, but Hayden will be joining us for the QOTD!  He is learning to read and identify his letters with more confidence in first grade, and he asked to be a part of the family blog last night.  So, I let him pick the animal.

I think I would still go with my original answer-a megalodon.  This is a giant, prehistoric shark.  Estimates taken from teeth put this predator at around 67 feet!  (though I think that is one of the biggest on record, so that might be a max) But when i think of a shark I think of a fierce predator, something that will defend what belongs to it with everything it has.  Something I imagine all parents can identify with.
