One of summer's most beloved traditions starts on July 28. That's right, it's Shark Week on Discovery Channel, where we learn all about the scary but thrilling predators of the sea.
Perhaps the most recognizable member of the shark family is the great white. Here are five facts you might not know about great white sharks.Shark Week 2019: 10 must-watch shows and specials
While shark attacks are rare, great whites are most often attributed to an unprovoked attack.
Great white, tiger and bull sharks are the three species of shark most likely to attack a human.
A great white's favorite snack is not a vulnerable swimmer — humans are too bony for sharks.
Great whites have no natural predator (except for killer whales on rare occasions), so they eat just about everything. Fish, other sharks, dolphins, seals, sea turtles, otters and seabirds are all known prey of great white sharks.
They can reach as long as 20 feet, but usually average around 14 feet for males and 16 feet for females.
"Bruce" was said to be 25 feet long in "Jaws."
Most great white attacks are actually "test bites."
Because of this, most great white attacks involve only one bite. Great whites use their mouths to get to know something — one chomp usually tells the shark whether the thing is worth eating.
Great white sharks (and most sharks in general) have to constantly move so they can breathe.
Sharks have to keep moving so that water can pass through their gills. This is even true when a shark in resting or sleeping. It was previously a big mystery on how sharks were able to rest and keep moving at the same time, but researchers caught a female great white in "an almost catatonic state," gliding lazily above the ocean floor with her mouth open, seemingly taking a nap.
