I like your story about your sister...it's cute! I have a hard time killing bugs which I hate, so fish are out of the question. I guess I can relate to your sister in that way. In response to your thought about turtles, and how they should have become extinct a long time ago, don't forget that turtles have very hard shells which they can hide their entire body in. Also, Bump said that they can live up to 300 years. I think that they are quite resilient animals and that's why they have survived much longer than us.
