The superior detail in the white shark's eyes

White sharks, which catch their prey by following it with their eyes, easily move around hot coral reefs. However, cold water causes them great trouble, for it usually retards chemical processes. But its eyes somehow manage to follow its fast-moving prey in cold ocean waters.

Allah created an incomparable and amazing solution to this supposed problem: unlike the white shark itself, its eyes are not cold-blooded. As a result, the heat of its bodily muscles is transmitted directly to the eyes, thereby allowing it to catch fast-moving fish and even seals with great ease.

There are many thought-provoking details related to how a cold-blooded animal that cannot store heat in its body can transmit heat to its eyes. Such an incredible system shows once again that the works and power of Almighty Allah, Who created the animal’s habitat and its special equipment, prevail everywhere. This example of sublime creation is a great blessing for humanity, because all of the proofs in and around people enable them to see and comprehend His sublime existence. The presence in a white shark of such a complex and detailed system, of which the animal itself is unaware, reminds us of His existence.

Every proof of Creation is a reason for people to draw closer to Allah and praise Him. The more they reflect upon these clear beauties and blessings, the more they will comprehend His Greatness. Any rational and conscious person can see the blessings that surround them; thus, they should constantly reflect on the fact that these are all reminders from Allah:
 

It is He Who is Allah in heaven and on Earth. He is the All-Wise, the All-Knowing. Blessed be Him to Whom belongs the sovereignty of the heavens and Earth and everything in between them. The knowledge of the Hour is with Him. You will be returned to Him. (Surat al-Zukhruf, 84-85)
