We & Shark


HUMAN AND SHARK

Ironically, humans continue to move into the natural habitat of sharks. Yet then we continue to blame sharks for destroying boats, surf boards, and are in shock when attacks on humans are reported.

In the early days of time sharks were viewed as heroes in Hawaii and as monsters in Japan. Those same differences still are evident today as some people hate and fear sharks. Others understand them though and do all they can to protect their very existence.

Sharks are very dominate in the waters where they live. They have been able to evolve and to survive for the past 450 million years. Yet their biggest threat is humans because of hunting, pollution, global warming, and taking over their natural habitat. Most humans don’t have any desire to learn the truth about sharks. They are content with the information they have even though it isn't accurate.


Anatomic Similarities of Sharks and Humans

It may surprise you to learn that humans and sharks are very distantly related to each other. There are many elements of them that have been found to be very similar. First, the sperm of the males is very much the same. Second, the components of the immune systems are very similar in make up. There are four types of white blood cells in mammals and that is the main connection here.

Many humans have taken up the interest of observing and monitoring the behaviors of sharks. Yet there is still so much about them that we don’t know. They are believed to have senses that are better enhanced than those of humans. They are also believed to be able to adapt to a variety of different situations in their environment.
The future for humans and sharks is one that remains uncertain. Hopefully there will come a time when enough information is out there that allows people to want to live in harmony with them. However, as long as humans continue to want to take over the waters for their own selfish needs it is going to be virtually impossible to find that balance.


Sharks are not Human Eaters

Those that fear sharks are developing a taste for human blood need to learn the facts. They aren't out there looking to eat humans for a meal. It is a proven fact that sharks can go for months without food so that isn't the case. They also aren't programmed to kill humans out of aggression.

There are very few shark attacks, less than 100 each year. Less than 10% of the individuals die when the shark involved couple easily kill them. Instead they leave the human alone after they realize it isn't what they thought it was. This shows a great deal of intelligence on the part of these creatures.


Humans in Shark Habitat

Sharks have no place else to go but in the water. Humans have the choice though of where they are going to be. Therefore it really isn’t fair at all to blame sharks when humans end up in their territory. Learning more about the distribution of sharks, their feeding habits, and even about their migration can help one to fully understand these fascinating creatures in the waters around the world.
Hopefully the humans that are willing to help protect sharks will be successful in their efforts. They strive to educate the public and to get them to recognize the importance of sharks. Sure, they can be large and they can be scary but they aren’t out there to consume humans. Very few species are ever a threat to humans in any form. It is very important to understand that sharks are a big part of the balance of the food chain in regards to the aquatic life out there.

WHAT...? SHARK!!!

INTRODUCTION OF SHARK

Sharks are a type of fish with a full cartilaginous skeleton and a highly streamlined body. Shark also known as Selachimorpha. The earliest sharks that exist in this world are known more than 420 million years ago.


SHARK FEATURES





 The smallest shark was only 17 centimetres and the largest shark that has been found from all over the world is 12 metres.








Sharks are found in all seas in the world and are common down to depths of 2,000 metres or 6,600 feet. They generally do not live in freshwater except for the bull shark and there are also some species that can live both of the water condition which is seawater and freshwater. They breathe through five to seven gill slits.





Sharks have a covering of dermal dentils that protects their skin from damage and parasites, and improves their fluid dynamics so the shark can move faster. They have several sets of replaceable teeth.
