Fantastic SHARK Diving at North Stradbroke Island (4K Ultra HD Underwater video)

North Stradbroke Island is a pristine, idilic island paradise, which is only one hour from central Brisbane.  Diving off Stradbroke Island can provides definitely the best scuba experience in South-East Queensland. It houses 15 amazing dive sites, each with unique landscape and marine life, all located only a 10- 15 minute boat ride from shore. While Manta Bommie dive site is definitely the main attraction for divers in Summer Months, in winter Sharks Alley becomes a shining perl of the island as dozens of endangered Grey Nurse sharks (also known as Sand Tiger Sharks or Ragged Tooth Sharks) gather in this area to bear the young. Obviously, it's not only the sharks that inhabit Sharks alley. This dive site is teaming with marine life: eagle rays, rock cods, octopus, anemonefish and many other species can be discovered at the rocky outcrops of the sharks gutter. Grey Nurse Sharks have suffered a decline over recent years, resulting in the listing of the east coast population as 'critically endangered'. Although the sharks are protected today, they were commercially fished quite extensively in the past. Moreover, in the 1950s and 1960s, the misconception that Grey Nurse Sharks were 'man-eaters' led to intensive fishing efforts by spearfishers using explosive headed spears. Tragically, the harmless and placid nature of these sharks made them easy targets. In 1984 this species became the first shark anywhere in the world to be safeguarded by the government, when it was listed a protected species in New South Wales. Today their population at the East Coast of Australia is recovering slowly, but steadily and it is a delight to see this magnificent creatures gathering every winter in increasing numbers. One of the curious aspects of the life of these still poorly understood species is what is called sibling cannibalism. Literally, the mother shark turns into a battleground for her young soon after the first and largest embryo hatched inside her reaches around 10cm long. The siblings that are conceived in the number of around 6 will then predate on each other until only one or two survive to be born. Surprising I was lucky enough to film this infrequently seen event at one of the dives and included this rare footage into this video for you! I hope you will enjoy watching!
