Which Sea Creature Has the Strongest Bite?

Reading this article, you can really see why some animals are so dangerous. While many of them are kept as pets, some others can't be domesticated. No matter how much we train some of them, the bottom line is that they're still wild animals. If some of us don't remember that, we could end up learning the hard way, through one of their vicious bites.

I feel that we sometimes tend to underestimate animals. Although the article doesn't mention this, dogs are another example of animals that have a very strong bite. This mainly comes from their lockjaw. They have a very tight grip, and once they grab a hold of something, it's nearly impossible to get off. Sometimes, the only solution is to kill it.

While some people might think that humans have an incredibly strong bite, even if that is true to some extent, it still doesn't hold a candle to that of animals. It's amazing how much of a force of nature they are. On another note, does anyone else wonder how strength bites in animals are tested? For example, the article says that bears have enough strength in their jaws to crush a bowling ball. While I don't doubt that this is true, what do they use to test this? I'm guessing that more than anything else, it's all about estimation.
