Well, I learn something new every day. I sure didn't know that salmon could become landlocked and keep on breeding.

I just remembered the giraffe term: reticulated! It comes from "net"! Must go post it on that other thread. It's cool how you'll forget a word and while writing about something else, the word pops into your head. I'm sure there's a psychological term for that kind of happening. (I amusingly thought "metriculated"--so close! And then the real term pops in. It's like having internal RAM--a program that keeps on running while you're doing or thinking about something else.)
