I know, I normaly do animals, but I decided to be special and do a plant. Actually, it's not a plant, it's a seed. The largest, heaviest seed in the world, in fact. Like the coconut crab, it is found in Seychelles, Africa. They grow on a tree, about 25-30 feet tall. The seeds themselves are 17 pounds, and as you can see, it is bigger then a boys head, shoulders and chest, all put together.   Originally, they were thought to grow on a mythical underwater tree. Those dang old ancient people are crazy, aren't they! Fangs sticking in pigs, underwater trees, what else?!
