Sharks – Hunters Of The Sea

April 1st, 2015

One of the most common fears of going into the ocean is the fear of shark attacks, although you may be interested to know that shark attacks kill less people every year than lightning. Sharks have been studied for many years, and have been around for millions of years. They are an extremely successful species, and their overall structure hasn’t changed much in the time that they have existed. In this article, we’ll take a brief look at some general information on sharks.

Sharks are carnivorous animals, and will attack virtually anything they think they can eat, provided they are hungry enough. Sharks have no actual bones because their skeletal structure is made from cartilage. Cartilage is a bone-like material that offers a greater amount of flexibility than bone. Sharks absorb oxygen into their system by taking in water through their gills, much like other types of fish, although unlike other types of fish the water is pushed through by swimming forwards. Therefore, if a shark stops swimming, it will fail to take in oxygen and die. It is an odd sight to see a shark at rest, because they will constantly drift forward in order to stay oxygenated.

Sharks are very good swimmers, and can reach very high speeds in water. They can live in both salt and freshwater. Sharks have a very good sense of smell, and can hunt using their sense of smell alone. The scent of blood in the water will often cause sharks to check out the source and see if it is a source of food. Their sense of sight is also pretty advanced, and they have membranes over their eyes to protect them from saltwater. Sharks also have incredible senses of hearing, although this may seem hard to believe. They can often hear the movement of prey miles away, and sense sound through catching the vibrations. Sharks even have organs that can sense electromagnetic signals given off by living things, and have hundreds and sometimes even thousands of these receptors throughout their body.

If this information is starting to scare you, keep in mind that very few people are actually attacked by sharks. Only a few people are killed by shark attacks each year worldwide, and many sharks will only attack a human being if they are starving, or if the person is mistaken for a type of prey the shark usually hunts for.

Sharks have been regarded as the hunters of the sea for many years, and have existed in relatively the same form as they are now for millions of years. Sharks have survived several eras during their existence, and are older than many types of dinosaurs. If you have an interest in these unique and amazing creatures, you’ll likely be interested in the huge variety of shark pictures available online. In this article, we’ll take a look at some of the various types of shark pictures you can expect to see while browsing the web, and a couple facts about how the pictures originate.

Shark pictures generally come in one of two forms photographs from biological studies in which the sharks are seen in their natural habitat, as well as photographs taken after sharks are caught (either accidentally or during shark fishing). These pictures sometimes include sharks in action, either hunting or even breaching the ocean’s surface for a snap at the camera. Shark pictures make great backgrounds for desktops or even themes for kids’ bedrooms if they’re interested in them.

Sharks represent all of the ferocity and danger inherent in the ocean, and are perhaps one of the most (if not the most) feared sea creatures. Some sharks are incredibly dangerous, although the types of sharks that are generally most feared (great white sharks, for example) are not the kind that you need to look out for most. One of the most dangerous types of shark is the tiger shark, which may not be the biggest or nastiest, but are certainly one of the most aggressive. Tiger sharks will eat almost anything they come into contact with, and are almost always hungry. If you want to try taking shark pictures of your own, you must make absolutely sure that you are safe within a certified shark tank and in the presence of trained professionals.

Shark pictures can be truly impressive when they are taken in their natural habitat, although there is very little more breathtaking to your family and friends than a photo of you holding up a full sized shark from a fishing line. Shark fishing is, of course, a dangerous sport, and should be taken seriously even if you plan on doing it just for the photos. There are lots of different types of shark photos out there, and there is sure to be several to match your taste.
