The Pardachirus marmoratus fish (finless sole, Red Sea Moses sole) repels sharks through its secretions. What scent do sharks hate? Excited by the scent of blood, a dozen sharks dart about in […]

In fact, sharks and their relatives were the first vertebrate predators on Earth. Shark fossils date back more than 400 million years – that means sharks managed to outlive the dinosaurs, survive mass extinctions, and continue to serve an important role near the top of underwater food chains.

It’s the flavor of the water that’s the key, he explains. First, he says, you scoop up some of the water from the ocean. Then put it in your mouth, swish it around and spit it out, the same way you would at a wine tasting. “If it tastes like salt, that means there’s sharks […]

Are shark shields effective? While Shark Shield can deter a shark from attacking, […]

In Africa it is estimated that an average of 2,900 people are killed by hippos each year. Which animal is more dangerous hippo or a shark? Hippos. You might not have guessed this, but hippos […]

We usually look at cows as docile creatures who stand around grazing until we use them for their milk or meat. But did you know that cows kill a whopping 20 people per year in the United States alone? By comparison, sharks kill only one person per year in the U.S. The average cow weighs […]

The deadliest animal in the world is the Asian cobra, causing nearly 50,000 fatalities a year. That’s followed by the puff adder snake, the ocellated carpet viper, the kissing bug, the assassin bug, the freshwater snail and the tsetse fly, all of which have more than 10,000 fatal encounters with humans a year.

This study confirms that dodecyl sulfate is the most effective surfactant shark repellent, but it does not meet the Navy’s potency requirement for a nondirectional surrounding-cloud type repellent of 100 parts per billion (0.1. μg ml−1). Is there a shark repellent that works? ESDs aim to overwhelm a shark’s electro-sensory system. They emit electrical pulses […]

And while this list is ordered based on how often attacks occur at each location, it should be noted that Australia, South Africa, and Reunion Island are currently the deadliest shark attack locations in the world. Where are the most dangerous sharks located? Publication Owlcation reports that Port Saint Johns beach in the Eastern Cape […]

Government officials often cite public safety (attempting to reduce the risk of shark attacks) as a reason for culling. The impact of culling is also minor compared to bycatch with 50 million sharks caught each year by the commercial fishing industry. Why are sharks being slaughtered? While sharks are caught as bycatch for human fisheries, […]

For those who still fear going in the water, Bangley suggests looking out for the following: Keeping an eye on birds/fish: If you see birds diving or fish jumping, that could be a indicator that a larger predator, perhaps a shark, could be attempting to prey upon a school of fish.

Some tour organizations use chum as bait, placing bloody fish parts in the water to attract sharks. Others bait, or “wrangle” the sharks, by throwing tuna tied to a rope into the water and pulling it toward the cage. It appears as though this practice was being used at the time of the recent incidents. […]
