I don't know about you, dear reader(s), but jellyfish scare the crap out of me. They're just...weird. They're goopy, tentacle-y, and they don't even have brains!!! How can we compete with such a beast???
I remember summers on the beach at Port Aransas as a kid, having to dodge beached jellyfish and Portuguese men-o-war (which also contributed, I'm sure, to a lifelong fear of Lusophones.)
Incidentally, having spent all of my childhood beachgoing at Port A and Corpus Christi, Texas, I was in my early teens before I learned that it is not normal, after a day at the beach, to sit in the tub and clean tar off of yourself. Thank you, offshore driliing industry!
Back to the jellyfish, though...if we're already having problems with depleted fisheries, melting glaciers, and oceanic "dead zones," the thought of angry swarms of jellyfish in coastal areas is, well, troublesome. I will be spending all of my vacations in mountainous inland areas from now on.
