Those were crawdads...
They were? See! This is what happens when you skip biology class in high school! Let this be a lesson to all high school students to attend each and every biology class unless you want to wind up like me...not knowing a crab from a crawdad. I did have a good excuse for missing class. I was showing my girlfriend how nobody could see you if you laid down on the bench seat of my pickup. Girls are much softer than bench seats.
