How is the archerfish able to do this?

Can archerfish shoot at human faces?

Archerfish ( Toxotes chatareus) are able to stick their faces out of a river or stream to spit jets of water with the precision of a master dart player, usually aiming at bugs and other prey on low-hanging leaves. During the study, scientists trained the fish to shoot at another kind of “bullseye” — human faces.

How do archerfish communicate?

This species has an unmistakable communication tool. Archerfish ( Toxotes chatareus) are able to stick their faces out of a river or stream to spit jets of water with the precision of a master dart player, usually aiming at bugs and other prey on low-hanging leaves.

How did scientists train fish to recognize human faces?

Archerfish are able to spit jets of water to hunt prey. Scientists harnessed this technique to train fish to recognize human faces. So just how did scientists know when the tropical fish — they used archerfish in the study — were able to recognize a face? This species has an unmistakable communication tool.

Do archerfish recognize human faces?

Fish Can Recognize and Remember Human Faces. After some training, archerfish can pick out a specific human face, researchers have found. (Image credit: Cait Newport) Archerfish Spit At Faces They Recognize, With Training | Video. Volume 0%.

Can fish recognize a human face on a computer screen?

Newport and her colleagues trained archerfish to select the “correct” image of a human face on a computer screen above their aquarium; for this fish, spitting a jet of water at an image is akin to pointing at it. “It takes time to train fish, and it can be a bit of an art; but it is not as difficult as you might think,” Newport told Live Science.

Do archerfish like water to be spread out?

This isn’t good for the archerfish, because water that is more spread out will strike the insect with less pressure (force divided by area). Fortunately for the archerfish, there’s another piece of physics that balances this tendency of the water to spread out. You might have noticed this second idea in your bathroom.

How do archer fish shoot out of their mouth?

Archer fish shoot a stream of water out of their mouths to knock flying prey items out of the air; they have great aim, too. These fish have been observed shooting at prey 5 feet (1.5 meters) above the surface of the water. When preparing to take down prey, they suck in water, place their tongue on the roof of their mouth, and then shoot.

What part of the brain is responsible for facial recognition?

The neocortex is a part of the brain that contains a visual-processing region as well as the fusiform gyrus, which is thought to be heavily involved in facial processing, the researchers noted. [ Video: Watch Archerfish Squirt Water at Images of Human Faces]

Can a fish recognize a human face?

A new study says, Yes, it probably can. Researchers studying archerfish found the fish can tell a familiar human face from dozens of new faces with surprising accuracy. This is a big, big deal. It’s the first time fish have demonstrated this ability.

Why did they use Archerfish in the brain experiment?

A fish was a good choice. Their brains lack the section that we use for facial recognition. That made them perfect as subjects for an experiment to see if simple brains can perform complex tasks. What’s an archerfish?

Can a computer recognize an animal’s face?

Until new technologies give us the ability to understand animals’ views on the panopticon, people have been almost disconcertingly audacious about training computers to recognize their faces. Humans don’t have a great track record for not harming animals, even when we know better.

Can fish recognize your face?

Fish Can Recognize Your Face. Really. There is some evidence that animals lacking a neocortex, namely bees and birds, are capable of some degree of human facial discrimination.” Crows and pigeons have been shown to recognize human faces especially well. Crows even recognize people in masks.

What can a fish-face database tell us about salmon health?

That fish-face database will potentially let farmers monitor salmon numbers and detect abnormalities in health, like parasitic sea lice, which could be a boon for farmers around the world. Salmon are just the latest entry in a growing cornucopia of animal faces loaded into databases.

Do fish need water to survive?

Our bodies and fishes’ (yes, fishes is a grammatically correct plural form of fish) bodies as well need water. Without it, the chemical reactions that take place constantly in our bodies would have no solvent and we would die. Nonetheless, it seems silly that an underwater creature should have to drink.

How do saltwater fish get water?

As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.

How do Fish absorb water?

Fish do absorb water through their skin and gills in a process called osmosis. Osmosis is the flow of water across membranes from areas of low concentration of dissolved things (solutes) to areas of high concentration. It serves to equalize the concentrations in the two areas.

How do archerfish shoot from their mouth?

Archerfish are able to shoot by putting their tongue against the roof of the mouth, forming a tube. By suddenly shutting their gills, water is then powerfully forced along the tube and out. The tip of the tongue directs the aim.

Where is the fusiform face area in the brain?

The occipital lobe is located near the back of the head. But faces seem to have a whole region of the brain dedicated to recognizing them. This is called the fusiform face area (FFA). There is a whole network of brain areas involved in face perception, but we’re going to focus on the FFA here.

What part of the brain is responsible for face recognition?

But faces seem to have a whole region of the brain dedicated to recognizing them. This is called the fusiform face area (FFA). There is a whole network of brain areas involved in face perception, but we’re going to focus on the FFA here.

Why do we recognize faces so well?

Our brains are so used to seeing them that we process them differently from most other types of objects. Holistic processing in the fusiform face area of our brains lets us recognize faces quickly and accurately. Even if we do slip up once and awhile!

How does your brain make sense of what your eyes tell you?

Your brain can only make sense of what your eyes tell it. But this communication is more complex than you’d think. Light goes into your eyes and hits a light-sensitive surface at the back. This is called the retina. The retina captures an image of what you’re looking at using photoreceptors . But the image your brain sees is upside down!

How do archerfish learn to shoot?

Young archerfish start shooting when they are about 2.5 cm (1 in) long but are inaccurate at first and must learn from experience. During this learning period, they hunt in small schools. This way, the probability is enhanced that at least one jet will hit its target.

How accurate are archerfish at shooting?

Archerfish are remarkably accurate in their shooting; an adult fish almost always hits the target on the first shot. Although it is presumed that all archerfish species do this, it has only been confirmed from T. blythii, T. chatareus and T. jaculatrix. They can bring down insects and other prey up to 3 m (10 ft) above the water’s surface.

How do archerfish recognize faces?

The research, carried out by a team of scientists from the University of Oxford (UK) and the University of Queensland (Australia), found that archerfish were able to learn and recognize faces with a high degree of accuracy—an impressive feat, given this task requires sophisticated visual recognition capabilities.

What animals can be monitored using facial recognition technology?

Is this strange animal’s face more human than canine?

Recently an adorable dog went viral for having a face that looked more human than canine. The cute pooch, named Nori, baffled people online who thought his face had been digitally altered. But now there’s another strange animal shocking people on the internet, only this one lives in water instead of on land.

Can dog and Cat facial recognition help you find your pet?

Dog and cat facial recognition has been around for several years now and is typically used as a tool to help distressed owners find their lost (or perhaps escaped) friends. One of these systems, called PiP, sends out an alert with the missing pet’s face to vet clinics and animal shelters within a 15-mile radius of the user.
