In places where there is a current, in order to survive, the growing larvae have to find something to hold on to. They easily shrug off this problem by using the support system on their bodies.

Some species of larva found in very fast flowing water have a long propeller attached to their bodies at a 45-degree angle. By means of small chitin hooks located at the tip of this propeller, the larva is able to keep a grip and protect itself from the current.

Mosquito house

Some mosquito larvae are born architects. These larvae, which do not have suckers with which to attach themselves to surfaces, build themselves houses to protect themselves from both enemies and the current. This is an interesting and surprising job, for each stage is full of difficulties.

First of all, the newly hatched larva has to feel the need for a house to provide security and protect it from the current, and with this in mind, to decide to build a house.

In the second phase, the larva has to make a plan. But a problem arises: The larva has no technical equipment or organ to use as a tool such as a beak, claws, paws, etc. Moreover, there are not many suitable materials to be found underwater for constructing a house.

However, the larva, whose every need is thought out in advance, already has the materials necessary for house building. It secretes a gelatine-like substance, which can easily be shaped. The larva, using this material to the best advantage in a way most suited to its own needs, makes a nest resembling a tube, which is open on both sides. It buries this tube in the mud or the sand or carries it around.

What is worth pointing out here is that the larva starts to build a house to protect itself as soon as it hatches from the egg, and it already has the necessary materials in its body, in a ready-to-use form.

Obviously some kind of training, and hence a certain knowledge of chemistry, is necessary to produce a substance that can easily be shaped underwater but which remains effective in water. As the larva is not a chemist, it is not possible for it to produce the secretion using its own intelligence and knowledge. It is completely senseless and illogical to consider such a possibility. Even if, in spite of the impossibility of the situation, we suppose that the larva has used its own skill and intelligence to produce such a substance, it is not feasible to think that it has installed the system producing the secretion in its own body. It is also obvious that it can't build such a nest and bury itself in the sand of its own accord.

Even if a larva acquires these characteristics, whether by chance or by experience, it cannot pass on its acquired knowledge to the next generation. If a living thing has innate knowledge, and if it uses this knowledge to best advantage and naturally possesses all the facilities and equipment to make use of this knowledge, this can only mean one thing: All these things are achieved under the control of a superior intelligence, and are created together with this creature. The superior intelligence that gives this knowledge and attributes to the creature, that brings everything into existence, is our Lord. It is expressed as follows in a verse of the Qur'an:

… Not even the smallest speck eludes your Lord, either on Earth or in heaven. Nor is there anything smaller than that, or larger, which is not recorded in a Glorious Book. (Qur'an, 10:61)
