Which Sea Creature Has the Strongest Bite?

The jumbo squid is a sea creature that has the strongest bite--it is estimated to have a force of more than a thousand pounds (455 kg). In comparison, a human bites into a piece of steak with 150 pounds (68kg) to 200 pounds (90 kg) of force. The force of the jumbo squid’s bite was measured by researcher’s observations of the sea creature biting a piece of Kevlar, a material 20 times stronger than steel used in bullet proof vests, in half. The white shark is estimated to have an even stronger bite than the jumbo squid at around 4,000 pounds of bite force; however, the figure was developed with a computer model and has not been measured in nature.

More about the bites strength of animals:

  • Saltwater crocodiles have one of the strongest bites of any animal and are able to bite with a force of 3,700 pounds (1678 kg)--this is thought to be even stronger than a Tyrannosaurus rex dinosaur.
  • A bear’s bite is estimated to be strong enough to crush a solid bowling ball.
  • Jaguars have the most powerful bite of any feline--nearly twice as strong as tigers.

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.
