In the sixth ayah of Surah Hud, Allah states that Allah gives the "sustenance" of all living things, that is, Allah creates all the provisions that provide for their subsistence:
How does a tree bring about such a yield? Why is it so useful to the human body? Why do all fruits contain essential vitamins appropriate to the seasons in which they grow? Why are they so tasty and not bitter? Why are they so fragrant and do not stink?
Certainly a tree is just a bulk of wood and it is out of the question for it to produce a fruit on its own and equip it with features essential for human use. Just as Allah sustains human beings, so does He sustain the animals. In the following pages, we will review the hunting techniques some living beings use to reach their sustenance.
It is by no means difficult for one to understand the might and omnipotence of Allah if one conscientiously examines, within the boundaries of wisdom and logic, the systems with which animals are endowed to get their food. Every animal that we cover in this chapter is one of the great examples Allah has spread out on the earth.
For instance, the "hunting technique" of the fish you see on the next page is amazing. This fish neither chases its enemy nor does it lurk secretly to dash upon them. The fish is no different from others at first glance. Yet, as soon as it lifts its fin, a "fake fish" appears on its back. When other fish approach this small fake fish, not realising who the real owner of the fins is, they become easy prey to the hunter fish.
Has this fish by itself given its fin a fish image? Or rather, have coincidences accumulated and given the fish such a feature? It is unquestionably impossible to claim that a fish could conceive of such a conscious plan, and act and carry it out. No doubt, all the features the living things possess bring us face to face with a single reality: the existence of the owner of the superior wisdom and design prevailing in nature, the existence of Allah...
2. In order to attract the attention of other fish, the fish opens its fin and the fake fish appears. 3. The prey, allured by the fake fish, draws near and becomes prey to the hunter it has not recognised. |
THE JUMPING SPIDER
The spider makes this amazing leap by its eight feet that work on hydraulic pressure principles, and all of a sudden it descends on its prey and inserts it powerful jaws in it. This leap usually takes place in a convoluted environment of plants. The spider must calculate the most appropriate angle for a successful leap, and consider the speed and direction of its prey.
The spider, however, does not face such an end. The spider thread, which it had secreted just before jumping and which it sticks on the branch it is on, saves it from falling to the ground and keeps him dangling in the air. This thread is so strong that it can hold both the spider and its prey.
Another interesting feature of this spider is that the poison it injects into its prey liquefies its tissues. The food of the spider is nothing else than the liquefied tissues of its prey.
Certainly, the features of this spider are not gifts (!) of coincidence. It is necessary that it should have gained the skill of both jumping and, at the same time, making a thread that will prevent it from falling. If it could not jump, it would starve and die. If it could not make a thread or if its thread were not strong enough, it would crash to the ground. Then the spider must both have a body structure suitable for jumping and a system to secrete a thread strong enough to lift its prey.
Besides that, the spider is not only a mechanism that produces thread and jumps but a complex living organism and must exist with all its features intact at the same time. The development of none of these features can be deferred. For instance, can you think of a spider with an incomplete digestive system?
| Another extremely interesting feature of the jumping spider is its skill in seeing. Many living organisms, including human beings, can only see a limited space with their two eyes and are unable to see behind them. However, the jumping spider can see everything around itself including its back with its four pairs of eyes located on top of its head. Two of these eyes are extended forward from the middle of the head like test-tubes. These two big eyes (called A.M. eyes) can move from right to left, and up and down in their sockets. The other four eyes on the sides of the head cannot perceive the image completely, yet can detect every movement around them. In this way, the animal can easily identify a prey behind it. |
CAMOUFLAGE TECHNIQUE OF THE ANTS
| Above are two ants and a jumping spider. You have no other way but to count the legs to find out which one is the ant and which one is the spider. |
The only difference between the ant and the spider is the number of legs. The spider has eight legs whereas the ant has six.
This fish shoots the water it has filled in its mouth on insects sitting on branches overhanging the water. The insect falls, due to the pressurised water and becomes an easy prey to the fish. It is worth noting that while launching the attack, the fish does not lift its head out of the water at all, and spots the location of its prey accurately. As is widely known, when viewed from under water, objects outside the water seem, due to the refraction of light, at a different location from where they really are. Therefore, to be able to "hit" a target outside the water from under the water, one needs to know the refractive angle of the light and make the "shot" accordingly. However, this fish innately copes with this difficulty and hits the mark every time. |
Yet, the camouflage does not consist solely of this. The animal needs also an eye pattern that will make it seem like an ant. Its own eyes are not big and in the shape of a dark spot like those of the ants. One feature it possesses by birth helps it solve this problem. The spider has two big spots at the two sides of its head. These two spots resemble the ant's eyes (notice the spots at the sides of the spider’s head in the above picture).
THE RATTLESNAKE
The heat-detectors located in the facial cavities at the anterior of the rattlesnake's head detect the infrared light caused by the body heat of its prey. This detection is so sensitive as to perceive a temperature increase of 1/300 in the heat of the setting. The snake, with the help of its forked-tongue, which is its organ of smell, can sense a motionless red squirrel sitting half a metre away in deep darkness. Fixing the location of its prey faultlessly, the snake first silently sneaks towards it, then comes close enough to attack, arches and stretches its neck and closes upon its target at great speed. By then, it has already inserted the teeth on its strong jaw, which can open to 180 degrees. All of this takes place at a speed equivalent to an automobile's accelerating from 0 km/h up to 90 km/h in half a second. The length of the snake's "venomous teeth", its greatest weapon in rendering its victim ineffective, is about 4 cm. The insides of its teeth are hollow and connected to the glands of venom. As soon as the snake bites, the gland’s muscles contract and with great power shoot the poison first into the teeth canal and then under the prey's skin. The snake venom either paralyses the central nervous system of the prey or causes its death by coagulating the blood. Only 0.028 g of some snakes’ venom is strong enough to kill 125,000 rats. The poison shows its effects so q uickly that the prey does not have time to do any harm to the snake. From now on, all that is left to the snake is to engulf its paralysed prey with its highly flexible mouth.
| This desert-dwelling snake can move swiftly on the sand. By contracting its chest muscles by degrees, it moves its body in an S-form. At the beginning of the movement, it twists its body, lifts its head and keeps it poised in the air. As the contraction, which drives the movement, proceeds to the tail, the head moves forward and touches the earth. In the meantime, the motion of contraction has reached the tail. A fresh wave lifts the tail up from the sand and brings it up to the level of the head. Thus, the snake moves forward by leaving parallel traces with a slope of 45 degrees on average. Throughout this movement, only two parts of the snake touch the sand. With this form of movement, the snake's body is protected from being scorched by making minimal contact with the extremely hot, burning sand.

| LION FISH After trapping smaller fish in cave-like or rocky shelters, this dazzlingly coloured fish closes their exits by using its fins as a net. Those fish that try to flee face the poisonous spines of the lion fish. The powerful venom of the lion fish takes instant effect and causes the deaths of its victims. |
Here, there is an extraordinary and unusual occurrence that we can only term a "miracle". It is, however, out of the question that nature could create a miracle which is "supernatural". Nature is a name given to the entire order we see around us. The founder of this order can surely not be the order itself. The laws of nature are those laws Allah fixed, which set the relationships among those that He created. Defining concepts properly reveals the truth. Confusing concepts, on the other hand, is a characteristic of the unbelievers. They do it to conceal the facts and deny the crystal-clear creation.
| WAR MACHINE: THE SCORPION Brain The brain's structure extends from head to tail and consists of fifteen nerve lobes. This structure of the brain provides a great advantage for the animal, allowing it to make quick decisions and to transmit reflexes and all necessary orders to the organs. Poisonous sting The potent poison of scorpions, which is capable of killing a human being, is injected into enemies via the stings located at the back of their body. A robust armour Its outer covering that wraps it like an armour is sturdy enough to protect it not only from its enemies but also from radiation. The human body has resistance to approximately 600 rads of radiation, whereas the tolerance of scorpions rises as high as 40-150 thousand rads. Lungs It has eight air vessels in its abdomen. It continues to breathe easily even if only one of them is open. It can stay under water for two days owing to its strong lungs. Abdomen On its underside , the female scorpion bears a pair of unique sense organs called "pectines". With these, it identifies the surface texture and selects the most appropriate place for laying its eggs. Feet The detectors on its feet help the animal perceive every kind of movement, noise and vibration. These detectors are so sensitive that the scorpion can sense the vibrations caused by a nearby living organism in 1/1000th of a second. Pincers The function of the scorpion's pincers is to render its victims ineffective before stinging them. Moreover, it can use its pincers to dig the sand and hide under ground. |

| The chameleon's tongue is kept collapsed within its mouth like an accordion. In the middle of its tongue is a sharp-ended cartilage. When the circular muscles at the tip of its tongue contract, the tongue shoots out. The animal's tongue is covered with a mucous-like viscous liquid. When it approaches close enough to its prey, it opens its mouth and rapidly hurls its tongue towards its victim. The viscous tongue, owing to the intertwining muscles, reaches as far as 1.5 times the length of the chameleon. The time for the tongue to retrieve the prey and retract is only 0.1 seconds. Camouflage The chameleon is certainly the first animal that comes to the mind when camouflage is raised. The chameleon changes its colour according to the ground on which it stands. To the right can be seen the mark made on the coat of the chameleon by the fern left on its back. Light and temperature changes are considered to have a role in the reactions that cause this mark. Yet, the animal is not even aware of its advantageous skill in changing colours. Its body is originally created to automatically match the colours of its surroundings. |
. AN UNCONVENTIONAL HUNTER: THE VENUS PLANT
The hunting system of this plant works as follows: a fly looking for food among the plants suddenly comes across one which is very attractive: the Venus plant. What makes this plant, which resembles a pair of hands holding a bowl, attractive, is its charming red colour and, more importantly, the sweet scent secreted by the glands surrounding its petals. The fly is charmed by this irresistible smell and lands on the plant without hesitation. While moving towards the origin of the food, it inevitably touches the seemingly harmless hair over the plant. After a short while, the plant suddenly snaps its petals shut. The fly is left tightly compressed between two petals. The Venus plant starts to secrete a "flesh dissolving" liquid, which causes the fly to turn into a jelly-like substance, and then the plant consumes the fly by absorbing it.
Research has shown that there exists an electrical system inside the Venus plant. The system works as follows: the strokes of the fly on the hairs of the plant are transmitted to the receptors under the hairs. If this mechanical push is strong enough, these receptors will send electrical signals along the petal, just like waves in a pool. These signals are carried to the motor cells that cause the petals to make sudden moves, and finally the mechanism is activated to swallow the fly.
| A few hairs inside the petals of the plant activate the trapping mechanism of the flower. |
1- The fly makes the hairs vibrate and the reaction starts. 2- Electrical impulses caused by chemical reactions are transmitted along the leaf. 3- And the plant catches the fly! |
Now, let us contemplate this striking system. The whole system has to exist at the same time for the plant to catch its prey and digest it properly. The absence of only one element would mean death for the plant. For instance, if there were no hairs inside the leaf, the plant would not close, as the reaction would never start although the insect would walk all over and inside the plant. If the closing system were there, but if the plant were devoid of secretions to digest the insect, the whole system would be useless. In brief, any element lacking in the system would mean the death of the plant.
This plant, since the moment it was created, must have always possessed the features we refer to here. The plant, no doubt, did not suddenly transform into a hunter. It is certainly not the "magical spell of coincidences" that has made the plant such a professional hunter.
