Great white sharks have many tools with which to protect themselves, such as powerful jaws, unique scales and efficient eyes. The shark has, in fact, evolved to be both a fierce predator and a defensible fortress.Continue Reading
One way that great white sharks protect themselves is with their powerful jaws. These jaws are not only strong, but they're also attached to the skull in such a way that the shark can take enormous bites and then retract its jaw to slice through flesh in self-defense or attack.
According to PBS, another self-protective feature is the great white shark's scales, or dermal denticles. The small, tightly overlapping scales give the shark a hard, protective layer of armor that can withstand much. Even the coloration of the scales is protective; the scales on the belly are white, while the scales on the back are gray. This allows the shark to blend into its watery surroundings from above and below, providing efficient camouflage for both protection and hunting.
Great white sharks also have unique eyes. In the event of attack, the shark can roll its eyes back in its head in order to protect them. The shark's fins give it the power and maneuverability to both protect itself and hunt down food.Learn more about Biology
To survive, great white sharks have evolved several behavioral adaptations, including flexible activity patterns, migratory habits and social hierarchies. However, great white sharks are also intelligent hunters, and their most important adaptation is their use of different strategies for different prey. Great whites are not commonly kept in captivity; so many aspects of their behavior remain unknown, as it is difficult to study them in the wild.Full Answer >
Great white sharks eat mainly seals and sea lions. They also eat other types of fish and even sea turtles. Seals are a good source for great white sharks due to their large body fat ratios.Full Answer >
The 400 living species of sharks defend themselves in a variety of ways that vary from species to species. Large species, such as great whites, basking sharks and whale sharks derive protection from their size; they are too big to represent potential prey for any species except humans. Other species, such as carpet sharks, rely on their flattened morphology and cryptic coloration to avoid the detection of predators.Full Answer >
Though sharks are considered apex predators, they are often eaten by humans and are sometimes eaten by killer whales. Shark embryos from different fathers will also eat each other in utero, with the largest embryo of the bunch usually winning out.Full Answer >
