Facts That You Should Know About Sharks
When most people think of sharks, they automatically reference the man eating predators, however, there is more to this type of fish than meets the publics’ eye. The facts about sharks, as well as the related concepts that are a part of them is one that can help to define this sea creature.
Evolution of Sharks
Sharks are known to be an ancient creature, with fossils from some of the oldest sharks dating back as far as 420-450 million years. Their evolution is one that has led to several species, sizes and structures that are linked to the pre-historic animal.
From the evolution of sharks, are also various kinds of these animals that exist. These are divided according to the shapes and features that are present in the animal. Features such as the fin, spine, nose and body shape help to determine the type of shark that is seen. For example, a white shark will have their mouth behind their eyes and will have a fin towards the front and towards the back. An angel shark, on the other hand, will have several fins that are along the spine as well as a flat nose with the mouth underneath.
Facts about some Shark Species
Not only do the evolutionary features define the look of a shark, but also determine how they survive in the wild. Not all sharks will constantly be searching in a particular area of the ocean for their food. There are three general types of sharks that will move according to the form and function of their body. This includes some sharks that will move at the upper part of
the ocean and will move at a slow pace, sharks that will be towards the middle of the ocean and will have a powerful force while swimming and sharks that stay at the bottom of the ocean, moving slowly and finding their food on the ocean floor.
With the various areas that sharks live, are also specific ways of living. Depending on the type of shark, the fish will either swim in groups or on their own. This is dependent on the way that they have found it is best to survive, specifically with the hunting skills that they acquired.
The habitat of sharks not only takes place in different levels of the ocean, but also is restricted to different areas. This is based on the activities that are needed, whether they need fresh or salt water, seasonal changes that are needed and temperature of the ocean. Typically, most sharks will be based around the warmer parts of the ocean, ranging from the central regions of the Americas to places around the tips of Africa, Australia and India. There are also cold water sharks that will be further south or north in the ocean.

Shark Myths De-Mystified
In modern times, the shark is known as a predator that will attack at the sight of blood. However, this myth of sharks is not necessarily accurate. In fact, shark attacks were less than 20 a year in the late 1800s. It has not been until the last two decades that shark attacks have become a more known factor in various areas of the globe. But contrary to popular belief, only some sharks are dangerous to humans, for example, Tiger shark or Great white shark.
It has been found that these attacks are not because sharks are typical predators. Typically, they will occur because there is a territorial threat or disturbance that occurs in the sharks inhabited area. At other times, these attacks will be ones that are provoked by humans, causing the shark to try to keep a safe ground. Things such as spear fishing and eco-tourism are contributions to sharks that feel the need to attack. Even among these attacks, it is only certain species that will feel a threat and will respond. Others will simply move into a different territory.
Through this predator fish is an evolution that has led to a specific lifestyle with sharks. In every area of the ocean is a type of shark that has moved into their living space, becoming one of the most known ocean dwelling creatures.
