CLEANING WORKERS OF THE SEAS

What occurs to you if you see a small fish that is about to enter the mouth of a big fish? You think that the big fish will swallow the small fish, and you wonder why the small fish comes so close to it.

It is undoubtedly unusual that the big fish lets the small fish swim around it, does not attack it and does not care about its swimming in its mouth or through its gills. It is, however, possible to see such scenes in the oceans a lot. It is not only some small fish that fearlessly swim around the big fish. Sometimes shrimps, too, may be seen near the mouths of big fish. These are cleaner shrimps whose job is to clean some of the big fish.

There are many kinds of cleaner shrimps. The one seen in the picture is one of them. The red and white stripes of the shrimp make it visible like a lighthouse and help the fish which is in need of cleaning find the shrimp. When the shrimp, with its two long white antennae, settle in on the fish, the fish begins to wait patiently for the shrimp to eat the parasites on its skin or on a wound. The cleaner shrimp can even enter the fish's mouth to remove disturbing parasites. In this way, it finds its own nourishment. The shrimp keeps working until it makes sure that the fish is clean all over. When the job is done, the big fish does not do the slightest harm to the shrimp, which in fact could be a lavish meal. The shrimp acts without worrying whether the big fish will attack or not. As seen in the picture on the previous page, these two creatures get along very well.

Concepts like "getting along well", "giving guarantee" are peculiar to humans who have intellect and intelligence, and therefore cannot be valid for these creatures. Yet, Allah, Who has control and power over all things, taught these creatures to behave so, to trust and co-operate with each other. So, they lead their lives easily.

THE NOISY CICADA

The cicada is a noisy insect. It produces ticks, buzzes and whines by means of a system in its body. There are a pair of membranous organs at the base of the insect's abdomen. The cicada produces that well-known sound by vibrating these drumlike membranes. When these membranes are pulled and released by the muscles to which they are attached, a sound similar to that of an empty tin is produced. The insect repeats this pull-and-release process 500 times a second. Considering that you can only close and reopen your eyes once in a second, you can readily see how difficult it is to perform this task 500 times a second.

With the opening and closing of the extended part that exists on the lower part of the insect's thorax, the sound level may be increased and decreased. The human ear cannot perceive these openings and closings, which occur in a tenth of a second, so we do not notice that the sound is interrupted and we think that the buzzing song of the cicada is continuous.

CLEANER BIRDS

The birds you see in the pictures are cleaner birds, which are called oxpeckers. These birds feed on the parasites that live on the hides of animals such as rhinoceroses, elephants and zebras. For this reason, these birds' perching upon them, even upon their heads does not bother such animals.

This partnership benefits both sides a lot. This way, the animals get rid of the bothersome parasites and are also warned by the birds, which screech in case of danger. In return, the birds obtain food and even hair to cover the inside of their nests.

Allah created this mutually beneficial relationship between animals. Allah created all these creatures along with the creatures that meet their needs.
