Introduction to Great White Sharks in New Zealand Waters
In the wake of a recent encounter between a Waitati spear fisherman and a great white shark, a marine scientist is reminding the public that there is no need to be concerned about swimming at Otago beaches. According to Prof Steve Wing, of the University of Otago, the risk of being bitten or eaten by a great white shark is extremely low, and Dunedin residents are more likely to die in a car crash on the way to the beach than to encounter a shark. Great white sharks are endangered and have been a protected species in New Zealand waters since 2007. Prof Wing, who has been diving for over 40 years, has only encountered two great whites in that time, highlighting just how rare these creatures are.
The Behavior of Great White Sharks
Great white sharks are attracted to the vibrations and blood of wounded fish, and are most commonly found in areas with abundant food sources. During the summer months, the waters around Otago and Southland are warmer and more appealing to great whites, who migrate from Australia and the Pacific Islands to feed on marine mammals such as seals and sea lions. Smaller sharks feed on fish and squid, but larger sharks, like the 4-metre great white that encountered the Waitati fisherman, prey on marine mammals. Occasionally, great whites may mistake humans for their preferred prey, emphasizing the importance of taking precautions when swimming in areas where they are known to exist.
Precautions for Avoiding Shark Encounters
To minimize the risk of encountering a great white shark, Prof Wing recommends swimming in groups, as sharks are less likely to attack a group of people. Additionally, avoiding murky or dark water, where sharks have difficulty identifying their prey, can also reduce the risk of an encounter. If a great white shark is encountered, it is essential to remain calm and maintain eye contact, as frantic movement can be mistaken for prey. Backing away slowly without splashing, and using any available object as a barrier, such as a spear gun or surfboard, can also help to deter an attack. In the event of an attack, targeting sensitive areas such as the nose, eyes, and gills can help to defend oneself.
Responding to a Shark Encounter
In the recent encounter between the Waitati fisherman and the great white shark, the fisherman’s actions were praised by Prof Wing and Shark Experience Bluff spokeswoman Nikki Ladd. By facing the danger, interacting with the shark, and slowly exiting the water, the fisherman was able to avoid a potentially disastrous outcome. Prof Wing emphasizes that the goal in such situations is to slowly and calmly exit the water, keeping the shark in sight and warning others of the potential danger. By following these guidelines and taking the necessary precautions, beachgoers can minimize their risk of encountering a great white shark and enjoy the ocean with confidence.
The Risk of Shark Attacks
Despite the recent encounter, Prof Wing stresses that the risk of shark attacks is low, and beachgoers should not be deterred from swimming. In fact, the risk of being attacked by a great white shark is lower than the risk of being involved in a car accident on the way to the beach. By swimming between the flags and following the guidance of lifeguards, the risk of a shark encounter can be further minimized. As Prof Wing notes, "it’s a calculated risk you have to take when you go in the ocean," but with the right precautions and knowledge, the risk can be significantly reduced.
Conclusion
In conclusion, while great white sharks do exist in New Zealand waters, the risk of encountering one is low, and beachgoers should not be deterred from swimming. By taking the necessary precautions, such as swimming in groups and avoiding murky or dark water, and knowing how to respond in the event of an encounter, individuals can minimize their risk and enjoy the ocean with confidence. As Prof Wing emphasizes, "it’s more dangerous to drive to the beach than to swim in the ocean," and with the right knowledge and precautions, the ocean can be a safe and enjoyable place to be.
