I've been told by a friend -- a wierd thing -- in many places you can dig a hole and it will fill with water. And at some point in the future fish will be swimming in it.

[fsckboy]

with a "pond sized" hole, I have read that fish eggs arrive on the feet of ducks and other waterfowl attracted to the new pond. (I have never looked up whether this is a myth)

There are also fish that can walk overland to find new ponds. Weird, but real, with obvious implications for the origin of land tetrapods.

Or trilobites?
