...which reminds me: Blues have very sharp, backwards-pointed teeth. One way of not impressing your friends is to catch one and use your finger to point at said teeth when enlightening your friends as to this fact. Your friends may find it humorous to see you running around like a girl after the Blue turns it's head and bites onto said finger... I, however, did not find it at all humorous (well ok, maybe a little) to have to walk ten minutes down the beach with a fish gnawing on my finger to enquire of a stranger if I could borrow their pliers to remove a fish from my digit.
Just some words of wisdom!
