Lights under surfboards could deter shark attacks

Sharks are easily distracted by bright lights, making them a potential target for non-invasive deterrents.

The Science Behind Shark Lights

Sharks have a unique visual system that is attuned to detecting movement and changes in light levels. This is due to the structure of their eyes, which contain a reflective layer called the tapetum lucidum. This layer helps to amplify available light, allowing sharks to see in low-light conditions. However, this also means that sharks are highly sensitive to light and can be easily distracted by bright or flashing lights. The tapetum lucidum is a reflective layer in the back of the shark’s eye that helps to amplify available light. Sharks have a highly sensitive visual system that is attuned to detecting movement and changes in light levels. The reflective layer in the eye helps sharks to see in low-light conditions.

The Potential of Shark Lights

Researchers at Macquarie University have been studying the use of lights to deter sharks from approaching surfers. The idea is that by using a light that is visible to sharks but not to humans, the shark’s attention can be diverted away from the surfer.

Shark Attack Data Reveals Trends and Patterns in Global Incidents.

The International Shark Attack File (ISAF) is the official global repository for shark attack data, and it is maintained by the Florida Museum of Natural History.

The Shark Attack Statistics

Overview of Shark Attack Data

The International Shark Attack File (ISAF) is the primary source for shark attack data. ISAF collects and analyzes data from around the world, providing a comprehensive overview of shark attack incidents. The data is used to identify trends, patterns, and hotspots of shark attacks.

Key Statistics

69 unprovoked shark bites in 2023

10 fatal shark attacks in 2023

Most attacks occur in the US, Australia, and South Africa

Most attacks are associated with people surfing and participating in other board sports

The Causes of Shark Attacks

Understanding Shark Behavior

Sharks are apex predators that play a crucial role in maintaining the health of marine ecosystems. However, they can also be unpredictable and pose a threat to humans. Understanding shark behavior is essential to reducing the risk of shark attacks.

Factors Contributing to Shark Attacks

Surfing and board sports: These activities can increase the likelihood of shark encounters due to the presence of bait fish and other prey. Swimming in areas with known shark activity: Ignorance of shark presence in a particular area can lead to increased risk of attack. Wearing shiny jewelry or bright clothing: Sharks are attracted to shiny objects and bright colors, which can increase the risk of attack.

Sharks avoid brightest lights, but why?

The Great White Shark Conundrum

The allure of bright lights can be a siren’s call for many marine animals, including great white sharks. However, researchers have discovered that these apex predators are less drawn to the most conspicuous lights. This finding has significant implications for the development of shark-friendly lighting systems.
