Sharks and dolphins are two of the most formidable creatures in the ocean, but while sharks are often seen as fearsome predators, they are known to be intimidated by dolphins.
Just like we check under our beds for monsters, sharks check for dolphins before nodding off. That's right, the toughest kids on the undersea block swim in fear of dolphins. Here, we've compiled a splash of facts to tell you why.
Larger predators give sharks the most fear. These could be killer whales, bigger sharks, a significant pod of dolphins, or even an alligator. Sharks also fear and avoid anything they don't recognize or understand. For this reason, sharks generally avoid contact with humans and their activities.
Usually, a hard blow to the shark's gills, eyes or snout (end of its nose) will cause it to retreat. These are really the only vulnerable areas on a shark. If you have a spear gun or pole, use it! A sharp object is a good way to inflict enough pain to scare away the shark.
Dolphins are not afraid of sharks. The majority of sharks aren't recognized for their speed or agility, so if the dolphins ever saw a shark in the wide ocean, they wouldn't have anything to be afraid of. Before they became their next meal, the only thing they could do was swim away from them.
Sharks are heavier, longer, and more deadly than dolphins. Sharks tend to be more independent than dolphins which live in pods that can include over 1,000 members! While they are smart in their own right, sharks are not nearly as intelligent as dolphins, but they are much more effective predators.
Slowly back away
Displace the least amount of water possible. Try not to thrash and splash around as you gradually swim backwards toward shore. “You must try and keep the animal in sight and very slowly and gently try and swim backwards and get into shallow water.
But sharks don't have the capacity to smell fear. That doesn't mean that a shark isn't impressive with its ability to detect prey from vast distances using its sense of smell, however. Fear is a complex emotion and a shark's olfactory system isn't sufficiently equipped to detect it.
There is no scientific evidence that suggests that sharks can smell fear in humans or any other animals. While it is true that sharks have an exceptional sense of smell, they use it primarily to locate prey, not to detect emotions like fear.
It has traditionally been believed that sharks are repelled by the smell of a dead shark; however, modern research has had mixed results. The Pardachirus marmoratus fish (finless sole, Red Sea Moses sole) repels sharks through its secretions.
Not if you plan on getting away. Despite the old saying that aiming for the snout is the best strategy, a shark's most sensitive areas are really its eyes and its gills. Aiming for the nose, which is not known to be a weak spot, is generally considered a bad idea.
Avoid wearing bright colors, such as oranges and yellows, in the water, as sharks can indeed see them.
Sharks may be fearsome predators, but they have a little weakness: Most can't tolerate fresh water (probably, a good thing to humans). About 40% of bony fish live in fresh water, but only 5% of elasmobranchs (sharks and rays) can manage this feat.
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.
But Dr Domeier used posts on Instagram to criticise Ms Ramsey for touching the animal and posing for photos, saying it could be damaging for the shark, which might be pregnant, and also send the wrong message to other divers. "The number 1 rule of legitimate shark diving operators is DON'T TOUCH THE SHARKS!
It is prejudice. Sharks do not circle in the water before they attack, it is simply their way of trying to form an image of what they are confronting in the water. According to my own numerous observations this motion is a sign of pure curiosity and not an incentive to circle its prey and feed.
Avoid being in the water during low light hours (dawn or dusk) and at night when many sharks are most active and feeding. Sharks have never been shown to be attracted to the smell of human blood, however, it may still be advisable to stay out of the water if bleeding from an open wound.
Sharks typically attempt to circle behind you to take a bite, so they will feel less comfortable if you keep an eye on them. Keep calm and slowly back away. If none of the above options are viable, you should fight back and focus your attacks on the shark's eyes and gills because of the areas' sensitivity.
Avoid swimming in areas known for sharks feeding such as rookeries and seal pupping grounds, Stay out of the water at dawn, dusk, and night, when some species of sharks may move inshore to feed on fish. Sharks are well equipped to locate prey even when visibility is poor.
Killer “whales,” which are actually dolphins, are apex predators, and their diet includes fish, squid, seals, sea birds and whales larger than themselves, according to the Natural History Museum in London. They are the only known predators of great white sharks.
A diver in south Australia captured stunning underwater footage of what's being called "the world's most beaten up shark." The 10-foot long Great White was covered nose to tail with scars.
No one knows why, but dolphins have been saving people for thousands of years. Dating back to Ancient Greece, there are dozens of claims of dolphins rescuing people from sharks, helping drowning sailors, and guiding boats through rough waters. But it's not just ancient mythology – it's still happening all the time.
