Diving With Grey Nurse Sharks in Australia

Diving with Grey Nurse Sharks are awe-inspiring experience. Also known as sand tigers or more formally as Carcharias Taurus , the sharks look scary. They are large, with large, highly visible, menacing teeth and swim slowly. But in reality they are relatively docile and more interested in nursing their own business than eating divers and fishermen.

Why dive with the sharks? Not only are they beautiful to look at, but they also have developed some fascinating features.

gray nurse sharks can grow to 4 feet in length and they are already mostly meter when you were born. They are usually brown / gray on their backs with white underneath. These sharks are incredibly fatty liver as a way to maintain their buoyancy, and they will also swallow air from the surface to help them float almost motionless above the seabed around the deep grooves and rocky caves. They like to eat fish, rays, crabs and lobsters.

These sharks are fascinating reproductive cycle. The embryos are grown in two cancer, and when they get big enough to eat their yolk sac, and then they'll eat each other. Just two baby sharks will survive, one in each uterus. Two years later, the mother gives birth to two one-meter miniature versions of adults ... complete with a fully formed teeth.

In Australia, there are two major and separate population of gray nurse shark. One along the east coast and one lives in the west.

Unfortunately, these sharks have been hunted almost to extinction. Along the eastern coast is estimated there are fewer than 1,000 individual animals lijevo.Siva sister is the difference that the first shark in the world became a protected species - way back in 1984. Unfortunately, since then, the shark east coast population has moved from "endangered species classification of the 'critically endangered' one, while the population along the west coast of Australia moved into the" vulnerable to extinction 'classification.

They are one of the most sharks are kept in public aquariums around the world as they are relatively easy to adapt to their captive environment. But if you're a diver place you want to see these animals in the wild.

There are several places along the eastern coast of Australia where you can do just that. With New South Wales coast known aggregation sites in Byron Bay, South West Rocks and Jervis Bay.

Diving at this site is truly amazing. At certain times of year you can be diving with 20 or 30 sharks at a time, cruising around. When you are next to one you realize how big of a 3-meter is actually much larger and older animals are very battle scarred. It is also an unfortunate fact that many of these sharks can be seen fishing with hooks hanging from his mouth.

and I have to admit it may take a minute to get used to the sight of a large shark with big teeth cruises slowly towards you, but generally if you stay still or move slowly to the side, you will be rewarded with a close-up view of animals sliding past you.
