Cats are a bit better at near vision. But both dogs and cats rely more on motion rather than focus, and are rather farsighted, an evolutionary side effect of scanning the distance for prey. A dog can detect strong hand signals from as far away as a mile.
Good eyes for one animal may not be so good for another. While many factors are to be considered when comparing eyesight amongst creatures, one thing for certain is that eagles take the crown for best all around eyes, primarily for their unprecedented ability to see clearly from far distances.
A cat's visual acuity is anywhere from 20/100 to 20/200, which means a cat has to be at 6 metres to see what an average human can see at 20 or 30 metres. Cats seem to be nearsighted, which means they cannot see far objects as well. The ability to see close objects would be well-suited for hunting and capturing prey.
Your Grumpy Pup Is a Very Smart Dog — Science Says So
That said, research has been divided on the dog/cat intelligence question, with some studies suggesting dogs are more intelligent than cats because of their social nature, while others found that cats rank higher in abilities, such as long-term memory.
When this scheme is applied to animals, the visual acuity of the typical dog is about 20/75, and the average cat is between 20/100 and 20/200. This means that from 20 feet away, normal dogs could distinguish the details of an object that a person with normal vision could differentiate from 75 feet away.
Although chitons look very simple, these mollusks have a very sophisticated shell. Its outer layer contains up to 1000 tiny eyes, each a bit smaller than the period at the end of this sentence.
One of the only animals with a wider range of vision than sheep and goats is the chameleon. Chameleons' eyes can swivel far enough to give them the full 360 degrees of vision. Beyond that, each of the chameleon's eyes can operates independently of the other.
The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8. The largest brains in the family Felidae are those of the tigers in Java and Bali. It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates.
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.
When it comes to the ongoing debate of dogs versus cats, we stopped keeping score a long time ago. But, here's a major point for the feline lovers: a recent study found that cats are just as loyal to their humans as dogs are.
Your Cat Stares at You to Show Affection
Cats can use staring as a nonverbal way of communicating. Even though a long, unblinking stare may not be the best way for humans to show affection, when your fur baby does this, it may mean they're showing love to their favourite owner.
Humans apart
Cats cannot differentiate between human faces and do not care how you look like. Unlike dogs, they would not even try to differentiate human faces. In an experiment conducted by an American university, the kitties could recognize their handlers less than 50 percent of the time.
While some cats are not bothered by the small screen, others will watch intently, particularly programmes featuring other animals. Some studies have indicated that cats are able to identify imagery on TV, as we know that they can distinguish between outlines, patterns and textures.
If you encounter an aggressive lion, stare him down. But not a leopard; avoid his gaze at all costs. In both cases, back away slowly; don't run.
The new research shows that dolphins have the longest memory yet known in any species other than people. Elephants and chimpanzees are thought to have similar abilities, but they haven't yet been tested, said study author Jason Bruck, an animal behaviorist at the University of Chicago.
Hawking, Gates and Einstein all have an IQ of 160. But Ramarni Wilfred, at age 11, scored 162, putting him in the top 1% in the UK.
IQ 166-clever, however, feels a bit hard to swallow. Originally Answered: How reliable is the source about Lady Gaga's IQ being 166?
William James Sidis has the World's Highest IQ. Anywhere from 250 to 300 is his IQ score, almost twice the score of Albert Einstein. At the age of eleven, William famously entered Harvard University, becoming the youngest person to enter. He also claimed to be conversant in 25 languages.
They can remember a person's face for up to 10 years! And kitties become seriously attached to their humans, so in case you were wondering, yes, your cat remembers and misses you when you're gone for a few weeks, and they absolutely mourn when a trusted companion drops out of their life.
Research has shown that “cat people” tend to be more intelligent than “dog people.” On top of that, the study found the pro-cat camp tends to be more creative, independent, and rebellious. However, the science suggests it isn't all negative for dog lovers – and not all positive for feline folks either.
The mantis shrimp's visual system is unique in the animal kingdom. Mantis shrimps, scientifically known as stomatopods, have compound eyes, a bit like a bee or a fly, made up of 10,000 small photoreceptive units.
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms).
