Somewhere in this blog, I wrote about a centipede catching a bat, and the eerie fascination of seeing a primitive animal hunt one farther up in evolution. Well here is another one. This one takes place in an aquarium.
So here is how the story goes. A number of four-foot long sharks are put in a big aquarium. But the aquarium keepers are worried because there is a red octopus in the same tank. Will the octopus be safe with these sharks roaming around? After all, one is merely a mollusk and the other is at the top of the food chain. Or is it?
Then they notice some sharks disappearing overnight. This goes on for a while, until somebody decides to stay up all night to solve the mystery. And they do. It turns out that the first assumption was very wrong indeed.
