“It is still a far cry from the 1960s, where aggregations of 30-plus grey nurse sharks were reliably spotted in 60 dive sites along Australia’s east coast, but it seems the population has been slowly growing since it became protected in 1984. I am writing it ‘seems’, because keeping track of this migratory species is a complex task.
“Also, their recovery is slow because it takes six to seven years for a grey nurse shark to reach sexual maturity, and they only breed every two years, giving birth to only two pups.
“Consequently, grey nurse sharks are not out of the woods yet, but with continued research and mitigation of the threats they still face, (e.g. accidental injury by fishing hooks, deadly if swallowed), I have hope that our kids will be able to dive with wild grey nurse sharks, and their grand-kids too!”
The winning photograph“This photo showcases the aggregation of critically endangered grey nurse sharks which can be seen around Fish Rock island (off South West Rocks, NSW, Australia),” explained Nicolas.
“The sharks are often scattered around the island, but on that summer day, the water temperature dropped overnight from 25 to 17 degrees Celsius, due to upwelling, caused by northerly winds. This drove the sharks to gather in the shallows, in search of extra warmth.
“Luckily my wife Lena and myself were in South West Rocks when it happened, and we dived every day for five days in a row, to make the best of these special conditions. Each morning, we would jump in the water for a single, three-hour-long rebreather dive.
“This gave us the chance to experience times of profound, serene contemplation, while being surrounded by 20 to 30 unbaited sharks, fully relaxed in the silence of our rebreathers.
“Within these hours of contemplative diving, there have been a few moments where everything lined-up, from an atmosphere and composition perspective. This photo depicts one of these moments.”
