Among hundreds of penguins, the mother easily
finds her spouse and offspring. As the mother has constantly hunted
in the meantime, it has a full stomach. It empties its stomach and
takes over the job of caring for the young.
In spring, the glaciers start to melt and holes emerge in the ice under which the sea appears. The parent penguins soon start to hunt fish in these holes and feed their young.
Feeding the baby is a tough task; sometimes the parents do not eat anything for a long time in order to feed the young. There is no way to make a nest when everything is covered with ice. The only thing the parents can do to protect their offspring from the ice cold is to put it on top of their feet and warm it with their tummy.
Timing is also very important in laying eggs.
Why do the penguins lay eggs in winter, and not
in summer? There is one reason for this: if they had laid eggs in
summer time, then the development of the offspring would take place
in winter time and the seas would be frozen. In that case, the parents
would have difficulty in finding food to feed the young due to the
inconvenient weather conditions and due to the fact that the seas,
the food resource of the penguins, are further away.
The reproductive system of kangaroos
is quite different from that of other mammals. The kangaroo embryo
goes through some stages outside the womb, which normally occur in
The offspring reaching the mother’s pouch attaches itself to one of the four nipples there, and starts to suckle.
At this stage, the mother goes through another ovulation period and a new egg forms in its womb. The female copulates once more and the new egg is fertilised.
This time the egg does not start to develop immediately. If drought rages in Middle Australia, as is often the case, the fertilised egg in the womb remains undeveloped until the drought is over. If, however, heavy rains fall and if there are rich pastures available, then the development of the egg restarts.
At this stage, we are faced with the question: who makes this calculation; who arranges the development of the egg according to the conditions outside? The egg cannot by any means make this arrangement itself; it is not a complete living being, it has no consciousness, and it is totally unaware of the weather conditions outside. The mother cannot make this arrangement, because, like all other living things, it has no control over the developments taking place in its body. This extraordinary event is definitely controlled by Allah, Who has created both the egg and the mother.
When weather conditions are convenient, thirty-three days after fertilisation, the new neonate, only as big as a bean, creeps up from the mouth of the womb and reaches the pouch just like its sibling did.
In the meantime, the first neonate in the pouch has grown considerably. It leads its life without doing any harm to its sibling, which is only one centimetre long. When it is 190 days old, it has grown mature enough to make its first journey outside the pouch. From then on, it starts to spend most of its time outside the pouch and leaves the pouch for good on the 235th day after its birth.
Soon after the birth of its second offspring, the female copulates again. Consequently, the female has three offspring all dependent on her. The first can feed on grass but occasionally comes back to its mother to suckle; the second younger offspring is still developing by suckling; the third is the neonate, which is the youngest.
What is more astonishing than that all three offspring, each in a different stage of development, are dependent on the mother, is that all three offspring are fed by different types of milk according to their sizes.
While the milk the offspring suckles as soon as it reaches the nipple in the pouch is transparent and colourless, it increasingly turns whiter and starts to look like real milk. The amount of fat and other ingredients in the milk increases in parallel with the development of the baby.
(Surah Fatir: 11)
As this young one keeps on suckling the milk prepared for its own needs, a more easily digestible milk issues from the nipple that the second baby reaches. Thus, the body of the mother simultaneously produces two types of milk with different ingredients. When the third is born, the number of milk types produced with different ingredients becomes three: highly nutritious milk for the older, and relatively less fatty and nutritious types of milk for the younger. Another point to note here is that each offspring finds the nipple specially prepared for itself. Otherwise, it would suckle milk with an ingredient likely to be harmful to its body, and the milk it suckles would harm it.
This feeding system is very remarkable and it is obviously a special product of creation. The mother cannot, by any means, arrange all these consciously. How can an animal specify the ingredients of milk needed by its young of different sizes? Even if it did, how could it produce it in its own body? How could it distribute these through three different channels?
the kangaroo is not capable of doing any of these. It is not even
aware that the milk delivered by its body is of three different
types. This wonderful process is unquestionably an outcome of the
created nature of this animal.
First, the animal digs a hole for the incubation of its eggs. The temperature of the hole should never rise above 30°C. A slight rise in temperature would be a threat to the lives of the offspring in the eggs. The crocodile takes precaution that the holes in which it places its eggs are located in rather shady places. This, however, may not in itself be sufficient. For this reason, the female crocodile spends extraordinary efforts to keep the eggs at a constant temperature.
Despite its bulky and wild look, the mother crocodile provides the utmost care for its young. It offers safe shelter to its unprotected babies in a special pouch in its mouth.
Some crocodile species build nests of weed on cold water, rather than digging holes (as seen in the picture to the left). If the temperature of the nest still rises despite these measures, then the crocodile cools the nest by sprinkling urea on it. When the eggs are about to crack, loud noises arise from the nest. These noises warn the mother that the critical moment has come. The mother crocodile brings the eggs out and helps the offspring pop out of their eggs by using its teeth as tweezers. The safest place for the newly born is the protective pouch in its mother's mouth specially designed to shelter half a dozen newly born crocodiles.
As seen, there is great co-operation and self-sacrifice among animals. For a sensible person, the perfect harmony in nature clearly reveals signs of the being of a superior Creator. That is, the signs of Allah, Who is the Creator of everything in the heavens and on the earth.
During the summer season, the female megapode lays one egg every six days. However, the eggs of the megapode are relatively big compared to its size, being almost as big as an ostrich egg. For this reason, the female megapode can only incubate one egg. Therefore, every six days, the new hatched eggs are in danger of dying due to lack of heat. However, this is not a problem for the megapode, because the male megapode is created with the skill to manufacture an incubation machine by using the most abundant materials in nature, that is, sand and earth.
While the male megapode digs a hole for its egg,the female only supervises without interfering at all. When the time to hatch comes, the eggs are taken out of the sand.
For this purpose, six months before the spawning season comes, the male megapode starts to dig a hole 5 metres in diameter and 1 metre in depth with its gigantic claws. Then, it fills the hole with wet weed and leaves. The main purpose is to use the heat produced by the bacteria in decaying plants to warm the eggs.
However, additional arrangements have to be made for this process to take place. The actual reason why plants decay and release heat is the funnel-shaped hole made by the megapode in the pile of plants. This hole enables rainwater to leak into the nest and keep the organic substances wet. Because of the damp, decay takes place in the plants beneath the sand, and heat is released. Soon before spring, the drought season for Australia starts, and the male begins to air the decayed plant layer. This is to maintain the heat balance. The female bird occasionally visits the hole and checks whether the male is working or not. Finally, the female lays eggs on the sand over the decayed plants.
How have these creatures accomplished such a
job for millions of years which even men could hardly do? Since
we know that animals have no conscious rational intellect as people
do, the only explanation of this event is that this creature is
specially "programmed" for this task, and originally created able
to do it. Otherwise, it is impossible to explain how it could prepare
for this job six months in advance, or know the nature of this complex
chemical process. Why it embarks on such a difficult task to protect
the eggs is another question. The only answer is hidden in the desire
to reproduce and protect the young.
The female cuckoo bird lays its eggs next to the eggs of another bird. For this, it observes at length a nest it chooses. As soon as the owner of the nest leaves, it secretly drops an egg in the nest. Meanwhile, it throws one of the eggs in the nest out so that the situation goes unnoticed.
When the time to lay eggs comes, the female cuckoo bird seems to race with time. Alert and on watch, the bird hides among the leaves and spies on other birds that build nests. When it sees a familiar bird building a nest, it decides when to lay its own egg. The bird to look after the offspring is now decided upon.
When the cuckoo bird sees that the other bird
lays its eggs, it swings into action. As soon as the other bird
leaves the nest, the cuckoo immediately flies to the nest and drops
its own egg in. Here, it does something very intelligent and throws
out one of the actual eggs belonging to the nest. This prevents
the owner of the nest from having any doubts.
The mother cuckoo works out a remarkable strategy with perfect timing to guarantee that its offspring makes a safe start in life. The female cuckoo lays not one egg but twenty eggs in a season. Accordingly, it has to find many nursing parents, spy on them and devise good timing to lay its eggs. Since the mother cuckoo lays one egg every two days and it takes five days for each egg to be formed in the ovary, the bird has no time to lose.
Popping out of the egg after an incubation period of twelve days, the cuckoo bird faces its very affectionate - yet not its own - parents as soon as it opens its eyes for the first time after four days. The first thing it does, as soon as it pops out of the egg, is to throw the other eggs out of the nest when the parents are away. The nursing parents carefully feed the offspring, which they take to be theirs. Towards week six when the offspring leaves the nest, we encounter the interesting sight of the cuckoo, a big bird fed by two small birds.
Let us think about why the cuckoo bird leaves its offspring to the care of other birds. Does the mother cuckoo have recourse to such a practice because it is too lazy or because it is not skilful enough to build a nest? Alternatively, is it because that once it used to build nests and look after its own offspring, but then realised that this is a very arduous task, and then it discovered this method? Do you think that a bird can make such a plan on its own?
Tarantulas generally hide themselves in the tunnels they dig underground. This wasp, however, is equipped with special sensors sensitive to the smell of the tarantula. Therefore, it is not so difficult for it to find its prey. The tarantula, however, is not a creature that is often found. For this reason, the wasp sometimes has to walk for hours on the ground to find a single tarantula. During this trip, it does not neglect to clean its sensors regularly so that they do not lose their sensitivity.
When the wasp finds the tarantula, a war breaks
out. The main weapon of the tarantula is its fatal poison. At the
outset of the struggle, the tarantula immediately bites the wasp.
Yet these wasps (pepsis) are protected against the poison of the
tarantula by possession of a special antidote and they are not affected
by the strong poison of the tarantula owing to that special secretion
in their body.
The wasp bites the tarantula on the upper left part of its stomach. This is the most appropriate area for the tarantula to be paralysed.
At this stage, the tarantula has nothing more to do against the wasp. It is now the wasp's turn to bite. The wasp bites the tarantula on the upper left part of its stomach and discharges its poison there. It is interesting that the wasp especially chooses this part in the tarantula’s body, because this is the most sensitive section of the tarantula. The most interesting part of the event starts after this stage: the poison of the wasp is placed in its body not to kill the tarantula but to paralyse it.
Carrying the paralysed tarantula to a suitable
place, the wasp digs a hole there and puts the tarantula in the
hole. Then the wasp makes a hole in the stomach of the tarantula
and leaves only one egg in it.
Within a few days, the offspring of the pepsis pops out of the egg. The offspring feeds on the flesh of the tarantula and takes shelter in its body until the cocoon period when it will undergo metamorphosis.
The pepsis has to find a tarantula for each one of the twenty eggs it will lay throughout the reproductive season.
method shows us that the reproductive system of this wasp is specially
created in accordance with the nature of the tarantula. Otherwise,
it is by no means possible to explain the presence of the antidote
in the wasp’s body against the poison of the tarantula, or its secreting
a fluid that paralyses the tarantula.
