The Interrogation
Where are you from?
I hail from Asia, Malaysia, and Indonesia. Some of my relatives also come from Africa. There are 28 different species of us, and since we look very similar, it's hard to tell us apart. There's at least four species in the U.S. so far. The more the merrier, I say!
How did you get here?
I arrived in the U.S. one of two ways. I used to be a popular aquarium fish, and occasionally my owners got tired of me growing and eating everything else in the tank and let me go in the nearest pond, lake, or river. Yippee, I'm free to stretch my fins! It's my understanding now that in many states I am "illegal" to possess because I am considered a "nuisance". Hmphf! There are also some humans who think I am a tasty treat, importing me into the U.S. and releasing me into a pond or lake on purpose, so that I can grow nice and big before they (shudder) catch and eat me! And they're worried about MY teeth?
I hear you can "get around" on your own without water. You’re just a fish - how’s that possible?
I may be a fish but if I don't find the waters I'm swimming in to my liking, I can travel across land to find new "digs". I don't even need to hold my breath - I can breathe air when I'm out of the water. I'm good for 3 or 4 days! Bet you can't hold your breath underwater for that long!
