Education brings awareness. Awareness brings action. These are key components for the safety of all. We educate on the important facts about our marine environment and how to enjoy it responsibly. This includes understanding that marine life is unique and should be respected. We inform the public on current laws regarding interacting with wildlife in a further attempt to spread a love and understanding of the ocean, not fear. Armed with important facts, a person is able to make an informed decision on whether to enter the water and the risks that may be present.
One of the solutions being considered by areas with a high incident of shark are devices designed to deter the shark from the source that emits an electromagnetic frequency are a very broad area. The concern for the use of such devices is the negative effect it may have on sea life.
A device that emits this frequency in a smaller radius provides the safety for the user without possibly damaging or interrupting the other sea life outside of that radius. The amount of EMF that is emitted can also have a negative affect so the size of the device is also important.
Powered by Shark Shield Technology, the Ocean Guardian FREEDOM7 gives you up to 6-hours protection from all predatory sharks – including Great Whites. Lightweight and designed to fit seamlessly with your existing gear, it offers powerful protection and peace of mind – so you can get out there and explore the ocean wilderness.
Shark Nark is intended to protect humans as well as marine life, not at the expense of the innocent animals merely trying to exist. After much research, Shark Nark believes that the small devices that can worn around one’s ankle or installed in a surfboard are the best choice for protection.
Why are these devices not being used by all ocean goers? The cost of these devices are higher than most people can afford to spend, especially if they aren’t avid users. While the organization is working hard to spread the word about these devices, they are unknown to most people. One of our goals is to purchase these expensive devices outright and make them available through local dive and surf shops for hourly use at a fraction of the cost to buy one.
When you Donate to Shark Nark you are helping us to achieve these goals. We can’t do this without the help of generous people and businesses, like yourself.
- Great White Sharks tend to hunt first thing in the morning, within the first two hours of sunrise when visibility is low.
- Sharks have six senses: Sight, smell, touch, taste, hearing, and electroreception.
- They use electromagnetic fields to feel vibrations in the water of potential prey.
- In close range, they can even sense the heartbeat of immobile prey.
- Great White Sharks live and hunt on the coast of every continent in the world the except Antarctica.
- Early fossil records show that Great White Sharks have been swimming in Earth’s oceans for around 16 million years, though scientists believe they may be much older.
- Clocking in at speeds up to 35 mph, Great White Sharks are some of the fastest predators in the oceans.
- Great white sharks have such a strong sense of smell that they can detect a colony of seals two miles away.
- Their sense of smell is so good they can detect the scent of blood in the water from up to three miles away.
- These cunning creatures like to take their prey by surprise. They usually position themselves underneath their unsuspecting victims before swimming up and…chomp! They often burst out of the water in a leap (called a breach) before falling back in with their meal in their mouths.
- When a great white gives birth, she usually has two to ten youngsters, called “pups“. But she shows no care for her offspring – in fact, she may even try to eat them! Taking care of themselves, the newborn pups will immediately swim off into the ocean.
- Great white sharks are at the top of the food chain and aren’t likely to be killed by other sea creatures. Sadly, however, they are under serious threat by human activity. Illegal hunting of these beautiful beasts, and overfishing, have meant that today great white sharks are a vulnerable species.
- Adult great white sharks grow to a maximum size of approximately 30+ feet in length and weigh up to 6,600 pounds.
- Scientists previously thought the life expectancy of a Great White Shark was around 25 years, but a recent study shows that their life expectancy is actually around 70 years.
- The heaviest Great White Shark ever recorded in the wild was estimated to weigh in at 7,328 pounds.
- Great whites play a special role in the ocean as a top predator by keeping prey populations such as elephant seals and sea lions in balance. The presence of great white sharks ultimately increases species stability and the diversity of the ocean.
- Great white sharks bear live young and females give birth to between two and 10 pups per litter, and perhaps as many as 14. Researchers think the gestation period is anywhere from 12-22 months which would only allow for breeding to occur approximately every other year.
- Male great white sharks generally arrive at the same time to the Farallon Islands off the California Coast and the offshore Island of Guadalupe, Mexico from late July through August, and females arrive to these locations several weeks thereafter. These sharks are observed at their coastal aggregation sites through February.
- Like most shark species, female Great White Sharks grow much larger than the males.
- In a single year, Great White Sharks eat average of 11 tons of food.
- Once they have fed, Great White Sharks can go a whole three months without having to eat another meal.
- They do not have eyelids, instead their eyes roll back into their heads to protect them from damage when attacking prey.
- A Great White Shark has a bite force of 4,000 psi, that is 10 times the bite force of a lion.
- Utilizing a practice known as “spy-hopping,” Great White Sharks will often peak their heads above water to look for prey.
- They tend to bite their prey, leave and let them weaken, before returning and finishing the kill.
- Sometimes during mating season Great White Sharks will share food, engaging in pack feeding of up to 8 sharks sharing the same meal.
- When Great White Sharks smell the blood of another Great White Shark, they will immediately leave the area, sometimes swimming hundreds of miles away.
- Great White Sharks cannot be kept in captivity because they become disoriented and will stop eating and continuously run into the aquarium walls until they die.
