Facts About Great White Sharks the Largest Predatory Sharks In the Oceans

Facts about great white sharks. Great white sharks largest predatory sharks.

One of the most fascinating predatory animals on earth at least in my opinion is the Great White Shark. The great white shark is the largest of the predatory sharks although it is not the largest shark. The great white shark can weigh anywhere from 5900 lbs up to over 7000 pounds and usually between 12 to 20 inches in length. Whale sharks are actually the biggest sharks and are nearly twice the size of the Great White Shark but they are not predatory creatures. They exist mostly off of plankton.

The great white shark females are often larger than the male great white sharks.

Sharks and Their Young

A great white shark has an even longer gestational period (amount of time it takes their young to develop inside of them) than human beings do. It can take up to 12 full months for a mother shark to give birth to their young. They usually only have 1 or 2 babies at a time. They usually travel to more shallow waters to give birth so their babies do not become the prey of other sharks but that is usually her last motherly gift to her children as Great White sharks are fully independent from birth and once they are born their mother no longer looks after them.

Life Expentancy

n optimal living conditions a Great white shark can live up to 30 to 50 years. They become sexually mature at around 7 years of age.

Great White Shark's Bodies

Great white sharks are amazing swimmers because of the shape of their bodies and thick oil in their liver that makes them more buoyant. Their body is thick in the middle where they carry much of their weight but the heads are pointed and their strong powerful tails are also pointed in a way that it helps to streamline them. Their tales do most of the work as they swim as they keep their body stiff as they move along using the power of its tail to propel it in the water. Although the great shark can be quick in pursuit of prey they actually swim very slowly through the water most of the time to conserve energy because they only dine on large prey such as tuna, dolphins, sea turtles, seabirds, seals, other sharks, and whale carcasses. Since it may be difficult to happen on to these animals that they prey on they may have to go several days without a meal so they conserve their energy. They can stop and rest either and must always keep moving because they need to force oxygenated water through their gills.

A Great White Shark's teeth is something you never want to get close and personal with unless perhaps they are out of the shark’s mouth. The teeth are very pointy and sharp and if that is not enough they are also serrated. Imagine a serrated knife and how it cuts through things this is how a sharks teeth are. You will never find a toothless Great white shark either, their sharp teeth eventually seer off, but once they do there are other teeth waiting to come in to replace them. Although Great White Sharks look like they have narrow mouths when they go to bite at their prey their lower jaws go down and protrude making a large opening and while when their mouths are closed it looks like their bottom teeth are set further behind their front teeth when the open their mouths to consume something they actually align.

Great white sharks have snouts. Their snouts are very effective in their search for food. The snouts have little sensors in them that help them pick up electrical nerve signals in their prey. Sharks are also very attracted to blood in the water and these sensors also help them to detect it. They can also begin to detect their prey by how the water tastes and the changes of the water pressure when suitable prey is near.

Where They Live

Great White Sharks can be found in many oceans across the world, but they tend to avoid extremely cold water and extremely warm water. They will often travel to seal colonies during the seals mating seasons and will feast on baby and injured seals.

Catching Their Prey

The Great White shark is a terrifying predatory animal and the prey will usually not sense the shark coming, the attack is usually a surprise as the shark comes in from behind the prey traveling at a great speed and slamming into it while taking a large flesh tearing bite at the same time as it thrashing its body and head back and forth to assist in the tearing of the flesh. Since a bite from the shark usually leads to quick death the shark will usually wait for its victim to die before going back to take another bite and finish off the prey. If shark does not like the taste after that first bite it will leave the prey behind. As far as human attacks go the reason many humans have survived is because once the shark bites their flesh they find they really don’t like the taste very much and don’t return for more. So if a human is rescued right away after a shark bite before they lose too much blood they do have a chance to survive the attack.

Their Kin Folk

Great white sharks are a part of the mackerel shark species of sharks. Mackerel sharks are all dangerous predatory hunters who are all streamlined and incredible hunters. Other types of Mackerel sharks include: salmon shark, shortfin mako, longfin mako, and porbeagle sharks. In total there are at least 51 different varieties of sharks. While most other varieties of sharks are not predatory they can still be dangerous if provoked.

So there you have it everything you ever or never wanted to know about Great White Sharks.
