Cockroach – An Amazing Insect
Cockroach is an insect that has beaten evolution without change
Many a times we would have encountered this amazing animal called COCKROACH, without realizing that it is “more a remarkable animal” than any other animal we can see in a zoo; but yet HUMBLE , and goes about its life without bothering about any happenings around.
Cockroach is one of the WORLD’s OLDEST INHABITANT, and the history of life has passed before its small sharp simple eyes as well as compound eyes.
Class Insecta (Hexapoda)
COCKROACH was there to greet the ARRIVAL OF DINOSAURS 170 MILLION YEARS AGO; he was there to bid FAREWELL TO DINOSAURS 100 MILLIONS AFTER.
COCKROACH IS AN AMAZIN ANMAL, THAT HAS LEARNT ABOUT SURVIVAL THAN HAS ANY OTHER ANIMAL IN THE WORLD.
The COCKROACH is an amazing insect in the universe.
Having a flat body they come under the classification BLATIDS. Cockroaches easily skitter away even when they are pressed hard under an elephant’s foot . They easily move away after the pressure is removed.
They can easily fit in crevices and underneath cleavages (CRYPTIC HABITAT) and walk into it with its flat body.
Cockroaches live anywhere from the hot Sahara to the cold Arctic and Antarctic.
Cockroaches have been found in the comfort of Modern TVs, Radios &Transistors, Balances and weighing machines in grocery shops etc, where the machine parts provide warmth and food in the form of wax, grease and other paraffin, that are an acceptable diet for them.
It must be remembered that of the 3500 known species of COCKROACHES , hardly 1 % seek human beings, their homes and environment as their neighbours.
Cockroach’s great survival is mainly due to its catholicity of food tastes .It can survive on ant thing from, flower buds, shoe leather, glues that hold Card boards together, paints, beer, clothes, and whatever you name. Cockroaches even eat its own cast of skin due to molting.
Cockroach’s survival is also due to its ability to fast, remain without food and water; two months on water alone, five months on dry food alone; and without any food and water for more than a month.
Most of us desist Cockroaches as filthy mainly due to their fetid odour. This odour is actually responsible for his survival as many predators of cockroaches too desist this odour and refuse to eat him. But Scorpions due the lack of scent organs relish and eat cockroaches.
Some of the forest dwelling tropical species of Cockroach are as large as small bird having 5 cm body length and a wing span of 13-14 cms.
Almost all cockroach species have wings. They fly only when all other means of escape fails.
Their main strength lies in its six long and powerful legs which takes them away from danger fast.
The most remarkable equipment that a cockroach has is its two Antennae , which are longer than the cockroach itself. These antennae help the cockroach feel its way in the dark.
The antennae of cockroach contain olfactory cells that help in detecting food and water.
The antennae also plays a key role in reproduction as they use they use they stroke their antennae to stimulate sexual interest in their partner.
Cockroaches are nocturnal insect (ACTIVE IN NIGHT). This habit helps the cockroach to avoid potential predators.
His three simple eyes and two compound eyes are very sensitive.
COCHROACHES ARE A PROLIFIC BREEDER. They reproduce very fast and increase their number. Some records shoe that they reproduced a record 180 offspring in about 303 days. There are reports of recovering as many as 475000 dead cockroaches from a barrack after fumigation.
The female cockroaches seem to be good mothers. Some species hatch eggs within their bodies and produce live roachlings. Most cockroaches carry a purse shaped egg sack with 12 to 40 eggs . These egg sacs protrude from their abdomen and are laid pastes to a corner of tree or wall. This hatch away to give white roachings that can survive about a week without food. But usually the mother cockroach deposits her egg sac near some food source and camouflages it.
Cockroaches can stand 100 times the nuclear radiation that human beings can endure.
A human being blacks out at 12 times EARTH’s gravity and his body suffers structural damage at 18 times Earth’s gravitational force.
Cockroaches can stand 100 times Earth’s gravitational pull for four hours and go about his business as usual.
USEFUL RESEARCH ANIMAL
As cockroaches are a hardy insect its use is valuable in cancer, heart diseases and nutritional research.
Many species help us by consuming dead vegetation that would otherwise clog forests.
Their anatomy has not changed from the beginning , though other animal species evolved.
The only animal (insect) whose direct ancestors have seen dinosaurs among others that is extinct today
Some SIX LEGGED INSECTS ARE KNOWN FOR THEIR PEDAGOGICAL ACHIEVEMENTS..
Honey bees are known for their industry.
Grass hoppers are known for their joy of living.
COCKROACH , nothing special other than living a simple life minding its own business, that has paid of in preserving its ORIGINALITY OF CREATION DURING THE COURSE OF 350 MILLION YEARS.
