Sturgeon: A fresh and saltwater fish with diamond shaped scales. diamondsides = nickname. "Whites" get bigger than "greens", but mostly you can't catch whites. Bottom feeders by design, hard to catch fun to play on a line.
My friends wife hooked a sturgeon but had never seen one. She pulled it up to the boat, took one look at it, screamed, threw the pole in the water, and jumped to the other side of the boat almost in tears. She did set the hook though.
