According to Live Science, researchers from the New South Wales Department of Primary Industries and Macquarie University in Australia tracked the movements of over 200 bull sharks.

The bull sharks were off the coast of New South Wales.

They published their results in the journal Biology.

It says swimmers should avoid water with bull sharks in the afternoon and in low light conditions.

In Australia, it is currently recommended to avoid water activities during dawn and dusk.

The researchers wrote: “We agree with current shark advice that nighttime swimming and surfing, particularly in warm waters and when water visibility is poor, should be avoided for many reasons, not least the possible presence of bull sharks.”

“However, we suggest that the reporting of the time of day for the presence of large bull sharks should be changed from ‘dawn and dusk’ to instead refer to afternoon and low light periods.”

Shark biologist Amy Smoothey was one of the lead researchers.

She told Live Science: “We found that the presence of large bull sharks was greatest from midday to 4 a.m.”

According to the study, there are also other conditions that swimmers and surfers should be aware of.

Unclear water, water with a temperature above 20 degrees Celsius and heavy rainfall should also be avoided.

Bull sharks can grow up to 11 feet and their attacks can be fatal.

The animals are found in coastal waters worldwide.

These include the east coast of America, the Gulf of Mexico and Australia.
