Food Web Woes

Who: Charles H. Peterson, Ransom Myers,

What: If sharks are extinct, that won't be good for the animals below the shark on the food web.

When: March 31, 2007

Where: The East Coast of the United States, Nova Scotia

Why: Researchers are studying this because they have noticed a large decrease in the eleven species of sharks and have noticed a large increase in other sea creatures

My Opinion:

My opinion about this is that it's interesting because when the biggest predator would die out the fish underneath them in the food web would suffer. That's so weird because you'd think since the big bad wolf is gone you'd be better off when in reality you suffer not having them around. Since the strongest animals isn't there to get rid of your predator, there are more predators that will be around to attack your species. I also wonder why when they were doing the study where the scientists put the shellfish in a place where there were poles protecting them from sting rays, I wanted to know why the sting ray didn't decide to just swim sideways through the poles and grab the fish. The researchers said that they didnt normally do that.
