Sharks are a type of fish. They belong to a group of fish called cartilaginous fish, which also includes rays and skates. Fish, in general, are a diverse group of aquatic animals with vertebrates, and sharks are a specific subgroup within this category. **

Great white sharks and whale sharks have different diets and feeding habits. Great white sharks primarily feed on marine mammals and other fish, while whale sharks are filter feeders that primarily consume plankton and small fish. Additionally, great white sharks are known to be more aggressive and territorial, and they may see whale sharks as non-threatening due to their different feeding behaviors. As a result, great white sharks are not likely to see whale sharks as prey and are more likely to coexist peacefully with them in the ocean. **

It is difficult to provide an exact number of how many sharks are left in the world due to the vastness of the world's oceans and the challenges in accurately counting shark populations. However, it is estimated that tens of millions of sharks are killed each year due to overfishing, bycatch, and habitat destruction. Many shark species are facing population declines and are considered vulnerable or endangered. Conservation efforts are crucial to protect these important apex predators and maintain healthy ocean ecosystems. **

Sharks are often portrayed as dangerous predators in popular media, but the reality is that shark attacks on humans are rare. Most shark species are not considered a threat to humans and do not actively seek out human prey. However, it is important to exercise caution and respect when swimming or diving in waters where sharks are present, as some species may exhibit aggressive behavior if provoked or feel threatened. Overall, sharks play a crucial role in maintaining the health of marine ecosystems and should be protected rather than feared. **

Sharks are not harmless, as they are powerful predators with sharp teeth and strong jaws. While most shark species do not pose a significant threat to humans, some species, such as great white sharks and tiger sharks, have been known to attack humans in rare cases. It is important to respect sharks and their natural behavior, and to take precautions when swimming or diving in waters where sharks are present. **

No, sharks are not blind. They have well-developed eyes that are adapted for hunting in low light conditions. Some species of sharks even have a reflective layer behind their retina called the tapetum lucidum, which enhances their vision in dark or murky waters. Sharks rely heavily on their vision to locate prey and navigate their environment. **

Sharks do not sneeze in the same way that humans do. They do not have a nose or nasal passages like mammals, so they do not have the ability to sneeze. However, sharks do have a way to expel debris or irritants from their gills by using a process called "gill ventilation" where they force water over their gills to remove any obstructions. **

Sharks are a type of fish that have cartilaginous skeletons, gill slits, and multiple rows of teeth. They are known for their sharp senses, powerful jaws, and streamlined bodies that allow them to be efficient predators in the ocean. There are over 400 different species of sharks, ranging in size from a few inches to over 40 feet long. Sharks play a crucial role in maintaining the balance of marine ecosystems by controlling populations of other marine animals. **
