Crabs – Why the crabs used to live in the burrows and holes?

The crabs are one of the living beings which are found on the sands of the ocean very usually. There are in total 6973 types of crabs that are available in the water. There are not only the crabs that are found in the water but also the crabs that live on the earth are also found on the earth.

Among all the crabs the smallest one id s the Endra crab which is very small in size and the biggest crab is the Japanese Spider Crab which is around 4 meters of width when it stretches its legs. There are in total ten legs for the crabs and among those legs two of them are very strong and have the formation of the nails of the birds at the end and edge.

The crabs used to capture the food using these nails and in the same way fight with the other crabs in getting their food from the enemies. There is an idea that these crabs are very greedy and dangerous as said by many scientists because these crabs do not satisfy with what they have to eat and used to fight with the other crab for the food and finally wins the battle and win the food of the other crab. In these wars and fights many crabs used to lose their nails and becomes weak.

The crabs will have a security layer on their body to protect themselves from the attack of the enemies. In case of the time passes away, the protection layer on the body of the crabs is lost and in place of that forms the new layer. During the time that is taken for the formation of the new layer, it is very difficult for the crabs to protect themselves from the attacks of the enemies. That is the reason why the crabs used to live in the burrows and holes to protect themselves from the enemies.

Current Shock for Birds | Why Birds on electric wires do not get shock?

Power supplied to the houses will have four kinds of wires. They are one neutral wire and three phase wire. Electric potential is present between two phase wires and between phase wire and neutral wire. For electricity to pass through an animal or an object, electric potential difference should be present between the two ends. That means the person getting shock should have connected to two wires.

Then, electrons pass from low potential wire to high potential wire. Passing of electrons through body is dangerous. Humans don’t get any effect if only one wire is touched. It becomes dangerous if two wires are touched simultaneously and if touched without wearing sandals. In case of birds, they won’t fall on the two wires simultaneously. So electricity is not passed through birds. If it keeps one leg on one wire and another leg on another wire by mistake, then it gets shocked. These incidents occur rarely.

Animal Engineering for food

It is a well known fact that only the human beings use the utensils for the daily purpose for their livelihood but this issue is said to be fake which is proved by many testing and practical’s.  Though animals cannot prepare the utensils as prepared by the human beings the animals can use the utensils and products which are available in nature.  Some of the animals act smart and completes their work though they don’t have any utensils with them.

The chimpanzees which take the food in the form of the insects try to get their food by searching inside the branches and leaves and satisfy their hunger.  Some monkeys tries to break the coconuts by cracking them to the stones and satisfies their hunger.  Some of the birds take the insects which are struck in the burrows of the trees from where the gum oozes out. In the same way the spiders web comes to the same stream.  With the help of the web which is constructed by the spider can catch the insects very easily and can have their food for the day.

It is proved in a survey which is conducted in Japan on Cockcrows says that the eating habits of the animals and insects changes according to the seasonal changes based on the type of food that is available.  The crow collect the wall nets from various places and throws them on the roads where the walkers cross the road. By that time when the vehicle passes on the nut the shell cracks and the nut comes out so that the crows can have their food for the day.  By these incidents and situations one can say that knowledge and talent is not only the treasure of  the human beings but also had the share for animals and insects on the earth.

Cockroaches Technologies to Robots | Know how of Cockroach running secrets

Cockroach is one of the insect which is not liked by many people in many areas. But this cockroach is saying lessons to the scientists to the excitement of all the people. The reason for this is as follows:

The run and fly of the cockroach is been captured by many cameras and video cameras and later on these stills are stored in the computer and these photographs are observed by the scientists and are surveying on hem. The latest news that is released by the scientists are as follows: it is said that with the speed of the cockroach, the robot can be prepared and those are the running robots but not the normal ones. It is the idea of the scientists to prepare the running robots even in the ups and down landscape too. You may get a doubt that why is only cockroaches for this experiment and not any other insect? In order to clarify this doubt, every one has to know about the specialty of the cockroaches.

Cockroach stands first in the row in the matter of speed and it even had a place in the Guinness record book. It is not that specialty but there are many specialties for this which made the cockroach very popular. It responds to every moment of the surroundings very quickly that is the reason why the scientists are doing a lot of research in this field. The robots are designed based on the speed, height levels and the functioning of the muscles of the cockroaches and they are even experimenting on the Guinea hen with the help of this cockroach. The scientists say that there are number of uses with these running robots.

Facts about Cockroaches

• The cockroaches can live for about 9 days even their head is cut.
• They can be alive without taking the breath for almost 45 minutes.
• They can live for one month without taking food.
• The width of the largest cockroach is around 6 inches.

Do Male Fishes and Female Fishes look alike? | How to differentiate them?

Fishes are one of the primitive organisms living on the earth since more than 42 crores of years. There are nearly 28,000 types of fishes. But scientists expect even more number if all the oceans are searched.  Living Organisms that live and respire in water are called as Fishes. All types of fishes will have spinal cord. Among these many types of fishes will respire through their gills. Likewise many types of fishes will have fins and scales on their body.

Fishes can be classified on the basis of the number of fins and scales, their characters, color and length. In some species, male and female fishes can be clearly differentiated in their body nature and color. Based on this, we can identify male and female fishes. But in some species there is no possibility to differentiate.

Though there are differences between male and female fishes we can identify them only by keen observation of some more characters. Not only fishes which swim, fishes which fly while swimming, there are also some fishes which walk on the land. For example, a fish called “Climbing perch” walks in search of a new water habitat when the present one dries up.

World’s longest Migration by Sterna Paradisaea

Generally all the living organisms on this earth will have the tendency of migration.   A bird called Sterna Paradisaea will migrate for a long distance of about 71,000 kms. It almost travels from the North Pole to the South Pole. The life span of this bird is 30 years and the distance traveled by this bird in its life time on an average is 24 lakhs kms. This is equal to traveling to the moon 3 times.

Don’t all the frogs have same kind of pupil?

We know that humans have rounded pupil while the cats have oval (vertical) pupil. Contradictory to this, frogs have different kinds of pupil. Frogs are categorized under one of the tail less amphibian class of 3 classes of Amphibia. There are almost 3,900 species. They can have different colored iris like red, green, brown, silver and gold depending upon the species. In same way, different species have different kind of eyelids.

Salamander type of frogs has rounded pupil like humans. While some species have vertical rod like pupil like that of cats, some have horizontal rod like pupil. Some have triangle shaped pupil while some have heart shaped one. It is surprising that some frogs have star shaped pupil also.

Frogs have eyes and nose on their head.  This facility will help them to respire and to observe surroundings while they are in water. In human history there is a funny fact regarding frogs. 2-3 hundreds of years ago, it was believed that frogs fell from the sky along with the rain.

Don’t fishes have ears? | How the fishes hear the sounds

Fishes are one of the ancient organisms present on the earth. It is amazing that fishes are living on this earth since nearly 450 million years from now. Till now scientists have discovered more than 25,000 species of fishes.

Fishes are cold blooded animals.  That means their body temperature vary according to the changes in the environmental temperatures. They say that fishes don’t have eyelids but it is not true in the case of all types of fishes. There are fishes with eyelids. But sleep or rest is necessary, no matter that the eyelids are present or not. So fishes take rest in different ways. For example while some fishes will be actively swimming in the day time and be stagnant in the night time, some others swim actively both day and night taking rest at intervals.

It is true that fishes don’t have ear lobes like us, but the organs present in the head, besides the eye and beneath the skin will receive the sound waves through the water and will respond accordingly. Just as the snakes receive the sound waves by ground vibrations, fishes receive sound waves through water, even though lacking external ear lobes.
