It is a story that has captivated marine biologists across the globe for nearly 50 years.
In 1975, the U.S. Fish and Wildlife Service (USFWS) identified the deadliest species of sharks in the world.
The sharks that were identified were the northern and eastern white sharks.
These were the most dangerous species of shark in the oceans of the world and they had been identified for years.
However, the southern and western white sharks are the species that have the most impact on the marine life of the ocean.
Scientists at the University of New South Wales have been studying these sharks since 2005.
“The northern and western whites are the most endangered sharks in our oceans, and this is because they are caught in the nets that are used to catch sharks,” said Dr. Jennifer J. Dickey, from the University’s School of Biological Sciences.
“The northern white shark is in the midst of a massive population decline, and is rapidly declining at an alarming rate.
We are not just focusing on their extinction, we are also looking at their future.
We have identified and are working with a variety of scientists to understand their conservation status, including sharks from the north and west, as well as northern and southern white sharks.”
Researchers also know that the western white shark, the most deadly of the species, is not only at the lowest point in its range, but also in decline.
It is now estimated that the population of this species is in decline from less than 200 animals in 1970 to less than 30 animals in 2016.
This is a species that has been the subject of much scientific interest, as its species numbers have been dropping dramatically, as have its populations.
The team also worked with other scientists to investigate the history of the northern white and southern whites, as the species is thought to have originated in the Gulf of California sometime between the late 19th and early 20th century.
To help identify the species’ fate, they collected specimens from both species, as they were used as a species comparison.
Researchers found that the northern species, known as the western, was more closely related to the southern white shark than the northern, as these species were thought to be of the same genus.
This was the result of scientists studying a few species of southern white and eastern whites.
They found that although the northern whites have the largest number of known populations, the population is not in fact decreasing.
In fact, researchers found that, since 1975, they have had an average of only 10% to 25% of the total population.
In the 1980s, Dr. Dixie began collecting southern white, eastern white, and western sharks from a range of locations around the world, from China to Australia, and they were able to compare them to the data collected over time.
What the researchers found was that, over the years, there was a clear trend toward the southern whites being more endangered, but the number of northern whites had remained relatively constant.
However, the study also found that in the late 1970s and early 1980s there were more northern white sharks found than southern white.
Dr. Dixons research showed that the eastern and northern whites are all related to one another, so it is likely that they are all descended from the same common ancestor.
The scientists also discovered that the number and size of these two populations fluctuated throughout the years.
If they were to breed, there is a possibility that they could have an advantage over other populations, as there are no records of them mating.
While they did not know for certain, they also discovered evidence that the populations of the two species are very similar.
“[It] seems like we have a good idea about the history and genetic makeup of these populations,” Dr. Jickels said.
“This is the first time we have been able to identify any evidence of a genetic relationship between these two species.
There is also an interesting biological interaction between the two populations.
One of the studies that we conducted shows that the size of the male dorsal fin and the size and the shape of the dorsal fin, which is characteristic of the eastern white shark are very closely related.
So, the males that have these dorsal fins have larger fins than the females, which indicates that the male that has the larger dorsal fin is more likely to be more aggressive and has more prey.
It also suggests that females are less likely to mate with males that they do not have a male that is larger than them, and that may be why the females are more likely than the males to mate.
Additionally, the researchers studied the genetic relationships of the southern, eastern, and northern white, finding that all three have a common ancestor in the middle of the Pleistocene, which occurred from about 6,000 to 6,500 years ago.
One of the largest shark populations that existed during this time period, the eastern whites were found in the southern Pacific.
They were known to be very territorial and territorial females,
