Splendour in the seas (Harun Yahya)
Splendour in the seas (Harun Yahya)
There's an incredibly wide range of life to be found on Earth. Millions of animals, plants, and insects live together in harmony on this blue planet.Such a wide range of life can only exist with the simultaneous existence of a large number of intricate balances. The distance of the Earth from the Sun, the angle of its axis, the speed at which it rotates, the components of its atmosphere, and the water which covers three-quarters of its surface, are just a few of the building blocks of this sensitive equilibrium.
The seas, which cover a large part of the Earth are an indispensable part of the equilibrium of Earth. Many events in the atmosphere, from rain to the formation of wind to the climate, are made possible by the existence of the seas.
Furthermore, the seas play host to billions of forms of life. This variety, which reigns hundreds, or even thousands, of meters under the sea, is just as astounding as that on the surface. These beauties in the undersea world spread God's incomparable creation, with all its systems, out before our eyes.
From fish to sea plants, from shell creatures to giant whales, from dolphins to planktons, innumerable forms of life make up part of this flawless part of the Earth. In this film, only a few examples of the amazing life under the sea are described. But even these few examples, from how these creatures find oxygen to their food, from their bodily structures to where they shelter, in short every detail, reveal that they have been created exactly suited to their needs. Because their Creator is the same as that of the environment they live in.
That Creator is the Most Glorious God, Who knows everything on the land and in the sea down to the very tiniest detail.
The environment that sea creatures inhabit offers them wide opportunities for feeding. However, most of the time, they too are in danger of being hunted by other creatures. For this reason defence mechanisms are of vital importance for living creatures beneath the sea. These creatures' defence and hunting techniques are really surprising. Although they possess no consciousness or intelligence, they exhibit the most well planned behaviour patterns. Some defend themselves from their enemies by mimicking another living creature, and others use poisonous spines. Yet others hide by demonstrating a remarkable resemblance to the colours and shapes of the environment they exist in. This is the camouflage method.
Camouflage is one of the most interesting techniques sea creatures use to protect themselves. Thanks to camouflage, fish can become quite invisible to their enemies. The bodies of these living things blend in with their environment to an amazing degree. To such extent that at first glance it is really hard to tell if they are plant or animal.
One of the living things, which protect itself by this method, is the scorpion fish.
It is impossible to distinguish a scorpion fish, hidden motionless among the coral, from its surroundings. Thanks to this property, the fish is saved from falling prey to big fish. The same property also allows it to hunt easily, without being seen.
This scorpion fish, perhaps the most interesting example of its kind, uses its claws as hooks while swimming. It moves along on the bottom of the sea, ready at all times to protect itself from any danger that might spring up around it. In an instant of danger, the scorpion fish rapidly deploys into the sand, with the aim of camouflaging. It submerges, and within moments becomes invisible. To the outside observer, it's nearly impossible to make out the motionless scorpion fish lying on the sea bed.
Another creature living beneath the sea which hides itself by camouflaging is the crab. Whenever danger arises, the crab conceals itself by burrowing into the sand and remaining there until the threat has passed. But at the same time it does not forget to keep its eyes, which is specifically created for this purpose, above the sand, so that it can still monitor what is going on around it.
Yet another sea creature which camouflages itself is the flounder. While this fish is moving along the surface of the water, a very interesting thing happens. The fish perceives the colour of the sea-bed over which it is swimming, and immediately changes its colour pattern to match it. It can change from a light grey colour, in a rocky or sandy area, to a green pattern when entering a region heavily infested with seaweed. This fish dwells in sandy areas, and it can immediately alter its pattern to match this background.
The underwater animals we have described so far were created so as to be able to camouflage their colours, tissues, and even their eyes. Eyes, that remain elevated even when the rest of their body lies buried beneath the sand, enabling them to safely examine their surroundings in concealment much like a periscope in a submarine
