Sharks defend themselves by utilizing their natural abilities, including their intelligence, heightened senses and strength. Another effective defense ability is their speed, as sharks are fast swimmers.
Even sharks, often thought of as the fiercest sea creatures, have to defend themselves on occasion. For example, smaller sharks might need to outrun larger sharks, while the biggest sharks, including the great white, often need to outsmart humans, their primary predator.
Sharks have a high level of intelligence, enabling them to defend themselves against predators. One example is the ability of some sharks to sink down to the ocean floor in an attempt to camouflage themselves. Additionally, sharks have heightened senses and use their powerful vision, smell and hearing to watch out for any nearby threats.
Sharks use their great speed to their advantage. These animals swim quickly, and in some instances top speeds of over 35 miles per hour.
The great white shark has fine-tuned vision and hearing, both of which act as defense mechanisms in potentially dangerous situations. The retina of the great white's eyes contains two distinct areas, one for seeing during the day, and the other for night vision, including low light and night lighting. When he feels threatened, this shark rolls his eyes back into his eye sockets.
