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.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
If you look at the life span and how quickly they have to learn things, it's a octopus hands down. Doesn't necessarily mean they know more than a dolphin at the time of death but they certainly learn quicker within a finite period of time so they are smarter in that they learn more quickly.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Are dolphins the smartest animals? Based on current metrics for intelligence, dolphins are one of the most intelligent animals in the world. While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts.
7. African Gray Parrots. African Gray Parrots are thought to be one of the most intelligent species on the planet, rivaling even apes. Some researchers have suggested that these parrots have a reasoning ability akin to a three- or four-year-old human child.
9: Octopus
No. 9 in our list is the octopus, one of the smartest creatures in the sea. This animal is still poorly understood, but scientists are constantly discovering new and impressive abilities. Octopuses play, solve problems, navigate through mazes and have respectable short-term memories.
1. Border collie. According to The Intelligence of Dogs, which ranks 131 dog breeds in terms of their relative intelligence, the border collie is the smartest dog breed known to man.
Scientists have studied both species and their brains to find the answer to this very question. And, scientifically speaking, dogs are likely smarter than cats. The research study looked at the brains of animals in the order Carnivora, a group of mammals containing bears, seals, raccoons as well as cats and dogs.
According to the BBC Science Focus, the smallest animal in the world is the Etruscan shrew. The Etruscan shrew, also known as the white-toothed pygmy shrew or Suncus etruscus, is located in North America.
Scientists compare the intelligence of crows to that of a seven-year-old human child. Crows, ravens, and other corvids are the only non-primates that make tools. Crows are capable of abstract reasoning, complex problem-solving, and group decision-making.
A dung beetle is not only the world's strongest insect but also the strongest animal on the planet compared to body weight. They can pull 1,141 times their own body weight. This is the equivalent of an average person pulling six double-decker buses full of people.
Recognizing themselves in a mirror, learning to perform certain behaviors and solve problems faster than other animals are some of the skills of pigs, considered to be one of the smartest species, even more than chimpanzees, dogs or dolphins.
According to research, cows are generally quite intelligent animals who can remember things for a long time. Animal behaviorists have found that they interact in socially complex ways, developing friendships over time and sometimes holding grudges against other cows who treat them badly.
They found that different brain regions use different strategies to interact with each other. This combination of complementary information between different sources is known as 'synergy' and may explain why the human brain is smarter than our primate ancestors.
So, YES, animals do have IQs and are trainable. They can be trained in order to sharpen their senses. Before winding up, take a look at my pet who has a much stronger IQ than I have!
These animals have been described in the Guinness Book of Records as the "most fearless animal in the world" A pair of honey badgers take on a pride of lions. It is not for nothing that the honey badger has earned the reputation of being the most fearless animal in the world.
In a battle royale for Most Powerful Animal, a red kangaroo might take the martial-arts belt, thanks to a bone-shattering kick that delivers 759 pounds of force.
Lions have famously acquired the title of 'King of the Jungle'.
Pigs have the intelligence of a human toddler and are ranked as the fifth most intelligent animal in the world! In fact, pigs are more intelligent and trainable than any breed of dog. They learn their names in just two weeks and come when they're called.
Crows are considered the smartest of all birds for several reasons. Furthermore, it's the variety of things they can do that puts them over the top.
The corvids (ravens, crows, jays, magpies, etc.) and psittacines (parrots, macaws, and cockatoos) are often considered the most intelligent birds, and are among the most intelligent animals in general. Pigeons, finches, domestic fowl, and birds of prey have also been common subjects of intelligence studies.
The smallest plankton (a single-celled alga, Micromonas pusilla) is some 19 billion times smaller than the largest whale (the Blue Whale, Balaenoptera musculus). Even if we include only multicellular animals, the smallest marine rotifer is some 840,000 times smaller than the largest whale.
