HOW CATS SEE AND TOUCH THE INVISIBLE

 

Did the title surprise you? Well, don’t be, for nothing shows that cats can see spirits. In this context, the “invisible” are visible things hidden from sight because of darkness. So how do cats find their way and even hunt comfortably in the dark? The secret lies in their whiskers, or vibrissae.

Cat whiskers are super sensitive to pressure, even air pressure. The slightest movement of air is noticed by these whiskers. How are they so equipped?

Cat whiskers are joined to tissues that are connected to so many sensitive threads called nerves. These nerves connect directly to the brain of cats and act as direct messengers to the brain. Since the connection process between the brain and the whiskers is almost direct and involves soft sensitive tissues and cells, the brain can easily detect even the things that pass by the whiskers.

Cat whiskers have a lot of functions that are not even fully understood. They can sense the movement of animals and obstacles around because of air pressure, even though the cat cannot see these things in the dark. Also, cats can use their whiskers to measure the size of a hole before they pass through it. How spectacular!

To help us fully understand how sensitiveness to air pressure enables cat whiskers to notice obstacles and animals, consider this illustration. If you close your eyes in a dark room and try to walk around very slowly, you will often notice you are close to the wall even before you hit it. You will be even more sensitive to obstacles if you blindfold yourself and try to walk outside. This sensation that makes us stop just before an obstacle is as a result of air pressure.

You see, even though you may not notice it, your skin relies on the movement of air flowing past it in order to notice obstacles. So when there is something blocking the airflow towards it or away from it, your skin takes notice of this change and your brain interprets it as an obstacle. And if something is moving towards you or if it passes in front of you, it pushes air according to its overall size. That movement of air is the science of air pressure. The amount of moving air you feel also tells you how big or how small an object close to you is.

According to scientists, if the whiskers of cats are cut off, the cats become unable to function for some time. What a wonder cats are adorned with!

GECKOS POSSESS PINS

“What for?” you may ask. After all, they could hurt someone or something, or they could even be hurt by their own pins. Amazingly, the pins are too tiny, soft and flexible to even hurt anyone or anything. That is why, if you’ve ever had a wall gecko climb on you, you would never see any scar on your body. The information you are about to read reveal the very reason gecko lizards can climb and walk on almost any surface. It was discovered that gecko lizards possess extremely tiny hairs under each of their feet. These hairs rise and flatten, and can be detached easily from surfaces because of the direction, or angle, in which they grow. These hair-like pins, more appropriately called setae , also have several smaller parts on each of them, making them look like ceiling brooms.  The tinier hairs, which are more of fiber, are called spatulae . The setae are made of keratin_ the same material human fingers are made of. Due to their structure, size, mass number and the material with ...

HOW SOME LIVING ORGANISMS USE THEIR LIGHT

You may have heard about living things that display colourful lights. In fact, plants like some fungi and algae species produce beautiful light at night. Fireflies produce light to attract prospective mates.  But some animals use their light for hunts or protection. Let's take some classic examples. Hunts Have you ever heard about a monstrous-looking fish called Deep-sea angler fish ? These deep sea little monsters produce light using bacteria living in the pole, or long organ on its head. By producing light on this organ and moving it back and forth, they succeed at getting the attention of smaller fishes. These smaller fishes find this attractive, but unfortunately they are being deceived . They only realize this once it is too late because as soon as they get too close to the hungry monster who is hunting stand-still, they are eaten at once! Protection And you're in here for 'special treats.' We would consider three amazing underwater creatures here, so let's get...
