There is no scientific way to measure the IQ of sharks. However, scientists have observed that sharks are intelligent creatures that can learn from experience and adapt to changing environments. Sharks have complex social behaviors and are capable of problem-solving and decision-making.
Great Whites and Manta Rays are among the most intelligent of the shark and ray species and are quite clever. But as far as we are aware based on what we know, are not on the same level that dolphins are. Sorry shark fans, but dolphins win here! Intelligence Winner: Dolphins!
most intelligent animals on the planet!
Most sharks are not dangerous to humans — people are not part of their natural diet. Despite their scary reputation, sharks rarely ever attack humans and would much rather feed on fish and marine mammals. Only about a dozen of the more than 300 species of sharks have been involved in attacks on humans.
Made of very strong and thick bone, dolphin snouts are biological battering rams. Dolphins will position themselves several yards under a shark and burst upwards jabbing their snout into the soft underbelly of the shark causing serious internal injuries. More than Peas in a Pod.
Memory and learning
Learning plays an important role in the lives of sharks, as has been well documented. Learning is closely involved with memory, and the sharks I had under observation frequently showed their ability to remember events far back in time.
In fact, sharks have displayed a wide range of personalities. A team from the University of Exeter and the Marine Biological Association of the UK (MBA) has been studying the behavior of spotted catsharks and have reported evidence of personalities.
It's estimated that dolphins have an IQ of around 45, this makes them one of the smartest animals in the world, and probably the smartest animal in the ocean. It's estimated that the dolphin's brain size is almost five times bigger than is usual for a creature of their size.
Sharks are often viewed as one of the ocean's top apex predators, but despite this rather prestigious classification, there's one marine animal that most sharks prefer to avoid crossing paths with entirely: the bottlenose dolphin.
Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
Now, new research has confirmed in detail the true culprit: a pair of orcas (Orcinus orca), hunting the sharks and slurping out their delicious, nutritious, vitamin-rich livers.
By their actions, sharks reveal that they are self-aware, form companionships, make swift decisions depending on the circumstances, and can plan to influence an event in the future. They enjoy socializing, communicate through posturing and gestures, and are capable of influencing each other.
The average dog's IQ is about 100. Based on the results done to test a dog's IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
Their ability to sense these movements may lead people to believe that they can sense fear but ultimately the movements help them locate their prey while they're hunting. Sharks can sense the earth's geomagnetic field, but they can't sense fear.
It turns out that sharks have more reason to fear humans than the other way around. That's why even shark encounter survivors have started speaking up in defense of sharks . While shark encounters do occur, they are actually extremely rare—despite the extensive media coverage they usually receive.
Porbeagles are one of the only shark species known to engage in playful behavior, just like dogs! They've been observed pushing floating objects and kelp around and chasing each other.
This makes it hard to verify and measure. So, do sharks feel pain? Yes – but it is different to how we express pain . Sharks do not have the same nervous system as mammals but what we do have in common are neurons called nociceptors.
So, while most sharks will be 100% fine if they stop swimming, a few iconic species such as great white sharks, whale sharks, hammerheads and mako sharks would suffocate without forward motion or a strong current flowing towards their mouths.
FACT: Sharks know the difference between fish and human blood and, while they can smell our blood, it is not a scent they associate with food. Scientific experiments have repeatedly shown that sharks have no interest in human blood.
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.
To say that dolphins and sharks hate each other is oversimplifying their relationship. They are more like acquaintances who prefer not to interact unless necessary. Let's agree to call them frenemies. You might have heard stories about dolphins “protecting” a human against a shark attack.
Dolphins are social animals and often join and leave other pods surprisingly frequently. They are also very protective of each other and their young. The dolphins probably sensed the danger and did what dolphins do, they tried to protect the swimmers, only leaving when they knew the shark had left.
