Here is a snipit from David Clouds newsletter.
THE AMAZING SPLASH FISH (Friday Church News Notes, October 19, 2007,
www.wayoflife.org [log in to unmask], 866-295-4143) - There is an
interesting fish that lives in South America called the splash tetra
(Copella arnoldi). It is a small elongated fish about 3 inches long
and lives near the banks of slow-moving rivers with heavy vegetation.
The male finds a suitable leaf hanging over the water and waits for a
female to join him. They then position themselves side by side and
leap out of the water at exactly the same time and stick to the leaf.
The female lays 6 to 8 eggs and the male fertilizes them, and they
drop back into the water. This process continues until they have laid
and fertilized about 200 eggs. The female then leaves, but the male
stays there for three days using his tail to splash water onto the
eggs every 10 or 15 minutes so they won't dry out. He does this until
the fry hatch and fall into the water. There is only one fish in the
world that does this neat trick. I would like someone to explain how
this amazing process could have evolved. First of all you would have
to evolve a male and female tetra fish with the amazing capabilities
of breathing underwater and reproducing offspring and such, all of
the incredible complexity of the fish at the genetic level. Then you
would have to evolve the splashing business. Assuming one fish
learned to jump out of the water and stick to a leaf, how did two of
them learn this at exactly the same time? It would have been
necessary that they perfect the trick the very first time or it would
have been meaningless. If only the male jumped or if only the female
jumped or if they both jumped but did not lay eggs and fertilize them
or if they jumped and laid and fertilized eggs but the male didn't
keep them wet -- nothing would have happened. And how did that
incredibly clever and gymnastic pair then pass this amazing process
along to their offspring who were not around to observe it?
