Coastal waters around Australia are often enjoyed for recreation, yet they are also home to diverse marine life.
A recent incident involving a visitor to a South Australian beach reminds us of the potential for unexpected interactions with these creatures.
This encounter resulted in a distressing experience for the individual involved, highlighting the need for awareness in such environments.
For many Australians, a day at the beach is one of life’s simple pleasures—sunshine, sand between your toes, and a refreshing dip in the ocean.
But for one South Australian woman, a recent trip to the coast turned into a harrowing ordeal after a close encounter with a surprisingly aggressive stingray.
A routine outing takes a shocking turn
Pam Bennett, a Yorke Peninsula local, was part of a group investigating the effects of an unusual algae bloom along the South Australian coastline. What began as a scientific outing quickly became a medical emergency when Pam was struck from behind in shallow water.
‘Suddenly felt this… what felt like a dog bite,’ Pam recalled. ‘At that moment, there probably wasn’t excruciating pain. The pain comes after.’
The culprit? An eagle ray, a species usually known for its shy and gentle nature. In a rare display of aggression, the ray’s 15-centimetre barb pierced Pam’s arm, narrowly missing a major artery. She was rushed to the Royal Adelaide Hospital for emergency treatment.
Despite the trauma, Pam is recovering well. ‘I’ve got a sore arm, that’s all,’ she said with remarkable composure.
What caused the stingray to attack?
Stingrays and their relatives, like eagle rays, are generally peaceful creatures. Attacks on humans are extremely rare, and when they do occur, it’s often because the animal feels threatened or startled.
But in this case, marine biologist Dr Mike Bossley, who witnessed the incident, believes something more unusual may be at play.
Dr Bossley, who narrowly avoided being struck himself, suspects the recent algae bloom could be affecting the behaviour of local marine life.
‘I’ve been snorkelling and diving for 50 years and never seen anything remotely like this,’ he said.
The algae bloom, fuelled by warmer-than-usual waters, can coat the gills of fish and rays, making it difficult for them to breathe. Stressed and disoriented, these animals may act unpredictably—even aggressively.
What is an algae bloom, and why does it matter?
Algae blooms occur when certain types of algae grow rapidly, often due to increased water temperatures or nutrient runoff from the land. While some blooms are harmless, others can deplete oxygen in the water or produce toxins, posing risks to both marine life and humans.
In this case, the Department of Primary Industries is investigating the bloom’s impact on South Australia’s coastal ecosystem. Dr Bossley suggests that only a strong storm from the south-west might break up the bloom and restore balance to the local waters.
How common are stingray injuries in Australia?
While stingray injuries are rare, they do happen, usually when someone accidentally steps on a ray hidden in the sand.
The most famous case was the tragic death of wildlife icon Steve Irwin in 2006, but most encounters result in minor injuries.
Stingray barbs are sharp and coated with venom, which can cause intense pain, swelling, and, in rare cases, more serious complications.
Immediate first aid, such as immersing the wound in hot water to neutralise the venom, and prompt medical attention, is crucial.
Staying safe in the water: tips for beachgoers
Shuffle your feet: When wading in shallow water, shuffle your feet along the sand to alert rays and give them a chance to swim away.
Be aware of your surroundings: Avoid swimming in areas with poor visibility or where marine life may be stressed, such as during an algae bloom.
Seek help immediately: If stung, get out of the water, rinse the wound with fresh water, and seek medical attention as soon as possible.
A reminder of nature’s unpredictability
Pam’s story is a timely reminder that even the most familiar environments can surprise us. As our climate changes and marine ecosystems face new pressures, unusual animal behaviour may become more common.
