The appearance of sea horses is very striking, and their general structure has a very specific design. Their size varies from about 4 to 30 centimeters(1.6 to 11.8 inches) and they usually live along the shore, among seaweed and other plants. A bony armor protects them from any kind of hazard. This armor is so strong that it is impossible to crush a dried, dead sea horse using only your hands.
The head of the sea horse is set at a right angle to its body. This feature is found in no other fish. Sea horses swim with their bodies straight up and they can bend their heads up and down. But they cannot turn their heads from side to side. This might cause sight problems in other creatures but sea horses have none thanks to their special body design. The sea horse's eyes can move independently, rotating about to watch each side so they can see their surroundings easily even without being able to move their heads from side to side.
The sea horse's swimming is also affected by a very special system. It rises and sinks in the water by changing the volume of the gas in its swim bladder. If this bladder is damaged and loses a little bit of gas, the sea horse sinks to the bottom. Such a mishap causes the sea horse to die. Here, there is a very important point that should not be missed. The amount of gas in the bladder has been adjusted in a very sensitive way. For this reason, the slightest change may cause the death of the creature. What this sensitive balance shows us is very important. A sea horse can survive only as long as this adjustment is maintained. In other words, a sea horse can survive because it has come into being with this system intact. This situation shows us that it would be impossible for sea horses to acquire their characteristics over time, that is, the sea horse is not a product of evolution as the evolutionists claim. Like all other creatures in the universe, Allah created them along with all their characteristics.
Probably the most amazing aspect of the sea horse is that the male, not the female, gives birth to its offspring. The male has a large pouch and a slit-like opening at the bottom of its abdomen, where it lacks armor plating. The female lays her eggs directly into this pouch and the male fertilizes them as they are dropped. The lining inside the pouch becomes sponge-like and filled with blood vessels, which are essential for nourishing the eggs. One or two months later he gives birth to little copies of himself.
The sea horse, which is only one of the millions of species living beneath the sea, has unique characteristics in many aspects. The design of the sea horse is just one example of Allah's boundless power and eternal knowledge:
...(He is ) the Originator of the heavens and earth. When He decides on something, He just says to it, "Be!" and it is. (Surat al-Baqara: 117)
