I found out about this amazing creature by watching a dvd called "incredible creatures that defy evolution 3".
NOTE: I cannot remember the name of the mussel but this mussel is closest to the one I observed on the dvd. The one I observed on the dvd may have been a relative.
This particular mussel has a very unique way of reproducing, in fact it is highly specific. The female mussel mantle looks like a minnow fish. It pumps water through its mantle and causes it to actually look like a little fish swimming in the water, it even has what looks like a mouth at one end opening and closing!
The reason it does this is because it is trying to attract specific varieties of fish (4 in fact) to come and eat them. The mantle has little mussel larvae on it which will attach itself to the predator fish. The hard part is, is that at a split second just as the fish goes to bite the mantle (and you know how fast they bite), the mantle has to react and fling the tiny mussel larvae into the water surrounding which then allows the mussel larvae to attach to the gills of the predator fish.
The larvae live there for a month and then drop to the ocean floor. It has to be on specific types of fish or else the little larvae die!
The questions that need to be asked is:
a. How did this mussel variety ever learn to be so quick as to be able to reproduce?
b. What did they do to survive when and if there was no bass, bluegill or sunfish?
c. How did this mussel learn or develop itself so as to look like a minnow? It even has two spots that look like eyes!
d. Looking at the evidence at hand, is it more likely that they were designed like that or that they happened to develop themselves like that?
