Animal Sense: 20 Things You Don't Know


The Animal Kingdom is a field full of mysteries. Studies of various species still seek answers that in the near future promise to surprise us - and a lot. For now, we may have our jaw dropping with what scientists already know, for example…

These 20 things about the meaning of animals:

1. Alligators are more sensitive than you think

Alligator skin is extremely sensitive to shifting vibrations, which helps them locate their prey.

2. Platypuses are sensitive

While alligators are touch sensitive, platypuses are the only electrorecepted mammals. With sensors in their beaks, they can detect electrical impulses emitted by their prey to locate them in murky waters.

3. Red Ants Predict Earthquakes

Researchers believe that electromagnetism can help red ants predict impending earthquakes (those that are about to happen) long enough to evacuate their mounds. So the expectation is that perhaps one day these creatures could be part of a geological threat detection system.

4. Elephants are also aware of soil vibrations

And they also use this sensitivity to preserve their species. It works like this: They use the seismic activity generated by their feet to communicate with each other about predators, territory demarcation, and mating preferences.

5. Star-nosed Moles have the most sensitive nose in the world

The nose of this mole species has 22 small trunks that contain a total of 100,000 nerve fibers. To give you an idea, this corresponds to six times more receivers than the human hand. As moles dig their burrows, these tentacles sweep the territory at high speed faster than the eye can detect.

6. Wolves have musical ears

In order not to lose their voice with howling choruses, they choose a specific note to communicate with each other.


7. Seals have hydrodynamic sensors

You may have noticed that seals have large, long mustaches, which are their trademark. They have a function that goes far beyond aesthetics. Through their whiskers, seals can detect the hydrodynamic trail of fish that are swimming up to 600 meters away.

8. Baby birds know when they need some nutrient

Feeling hungry is one thing. But knowing exactly what type of nutrient your body is missing is a completely different and, we must agree, impressive. White-crowned birds can do that. They realize the need to look for foods rich in amino acids that they cannot produce or store in their bodies.

9. Catfish have taste buds

The tongue of this fish species helps them detect prey by taste in any direction.

10. Worms feel changes in the soil

Earthworm bodies are covered by chemoreceptors that detect chemical changes and make these animals taste.

11. The language of snakes helps them locate prey

The tongue of snakes does much more than just taste the food. With their forked anatomy, they pick up odorous molecules from other animals through specialized ducts and send them to Jacobson's organ, which can detect where the source of the smell is located.

12. Common mice and worms may smell differently in each nostril.

Yes, your nostrils act independently. Even researchers are putting their talents to work in favor of detecting landmines and other explosives in Africa.

13. Sharks have a keen sense of smell

Up to 40% of shark brains are dedicated to smell. No wonder some experts believe they can sniff out prey up to 500 meters away in the open sea.

14. Parasitic worms also use smell to find hosts.

This ability to identify attractive odors makes researchers imagine that someday they will be able to develop these worms to treat disease. How this will happen is an answer only the future knows.

15. Vision is an essential sense for a bird of prey.

More than the smell. Even while diving at a speed of 160 km / h or more, hawks can detect their prey in part thanks to a decrease in the number of blood vessels in their retina. Since the vessels scatter the light, having fewer of them creates extremely sharp images, making the boat much more accurate.

16. Scallops are able to distinguish light and dark

These mollusks are not hawks, but some scientists believe they are able to distinguish between light and dark by having more than 100 eyes on the edge of their cloak. A reflective surface on the back of each eye focuses light on the retina to form clear images.

17. The four-eyed fish sees double

The fish of the species Anableps anableps, known as four-eyes, has only two eyes, but can see twice as each one is divided: the upper one watches over predators above the surface, while the lower one keeps an eye on underwater threats.

18. Some spider species can detect ultraviolet radiation

In addition to jumping spiders having no less than eight eyes positioned to create a nearly 360 degree view, some other species can detect ultraviolet radiation, which makes mating easier.

19. Worker bees are sensitive to changes in the earth's magnetic field.

Worker bees navigate using paramagnetic iron oxide rings that exist on their abdomens and that may swell or shrink, depending on the magnetic changes they feel. This eventually allows insects to find their way home, following changes in the Earth's magnetic field.

20. Beetle species can detect infrared radiation

Buprestidae beetles have sensors that detect infrared radiation from forest fires that are happening up to about 80 kilometers away. And then we wonder: what's the need for this? The answer is simple: Beetles use newly burned areas to mate. That is, it is a resource for the survival of the species.
