Hmm

[maderr]

Now there's an interesting idea. Not my cup of tea, but I'm sure someone somewhere would like it, if they have not already used it. I've seen this episode of Good Eats before, it's on shrimp. One of the little blurbs they toss up says that some shrimp change sex from male to female after one year of sexual activity. That would be an interesting concept to play with - a species where they start out one gender, but after x number of years switch to the other. I wonder what the reasons for that would be?
