Whale sharks, the gentle giants of the ocean, often fascinate both marine enthusiasts and curious minds alike. One question that frequently arises is, “Do whale sharks have teeth on their eyes?” This query stems from various myths and misconceptions about these massive creatures. In this article, we will dive deep into the subject, clarify the truth, and explore the fascinating world of whale shark teeth.
The Whale Shark’s Unique Anatomy
Before addressing the specific question of whether whale sharks have teeth on their eyes, it’s important to first understand their anatomy. Whale sharks are the largest known fish in the ocean, growing up to 40 feet in length or more. Despite their size, they are filter feeders, meaning they primarily feed on plankton, krill, and small fish, rather than actively hunting larger prey like many other sharks.
The whale shark’s mouth is located at the front of its head, and it is lined with tiny teeth and dermal denticles—small, tooth-like structures—on its skin. However, these teeth are not used for biting or chewing food. Instead, they may serve a variety of purposes, such as aiding in the filtration of plankton as the whale shark swims through the water.
Whale Shark Teeth: What Are They?
While the idea of teeth on whale sharks’ eyes may sound strange, understanding their actual tooth structure is essential. Whale sharks possess hundreds of tiny, conical teeth located in their mouth, but their teeth are not for predation. They are incredibly small and are used to help the shark trap plankton, krill, and small fish as it filters the water.
These teeth are part of the whale shark’s feeding mechanism. The sharks swim with their mouths wide open, allowing water and food to flow through their gills. The teeth and dermal denticles help to keep plankton and other small organisms inside the shark’s mouth, where it can filter them out for nourishment.
Despite the shark’s massive size, its teeth are not a major part of its feeding process. Their true role is more related to helping with the mechanical filtration of their diet.
Do Whale Sharks Have Teeth on Their Eyes?
The question, “Do whale sharks have teeth on their eyes?” can likely be traced back to a visual misconception. Some may have observed the unique, textured surface of the whale shark’s skin near the eyes and confused these structures with teeth. However, the reality is that whale sharks do not have teeth on their eyes.
Whale sharks do have small, rough dermal denticles covering most of their body, including the area around their eyes. These denticles are similar in structure to teeth but are much smaller and are used primarily for reducing drag as the whale shark swims through the water. These dermal denticles are not used for feeding, and there are no teeth located on or near the eyes of whale sharks.
The dermal denticles, or “skin teeth,” are an essential feature for the whale shark, providing protection and helping to streamline its movements in the water. They are also found on other sharks, though in some species, they may be more pronounced.
The Role of Dermal Denticles
While dermal denticles are often confused with teeth, they are quite different in both form and function. Dermal denticles are made of dentin, just like teeth, but they are embedded in the skin and are not used for biting or chewing. These structures help reduce friction in the water, allowing the whale shark to glide effortlessly through the ocean with minimal resistance.
In addition to reducing drag, dermal denticles can also protect the whale shark from injury. They act as a tough armor, preventing scratches or damage from other marine creatures or objects in the environment. These denticles also play a role in the shark’s ability to sense its surroundings, as they are sensitive to vibrations in the water.
Whale Shark Teeth and Their Feeding Mechanism
As mentioned, whale sharks have teeth in their mouths, but these teeth play a limited role in their feeding behavior. The primary function of their teeth is to assist in trapping food particles while they filter feed. However, it’s important to note that whale sharks are not actively hunting and do not use their teeth in the same way that other sharks or carnivores might.
When a whale shark feeds, it swims with its mouth wide open, allowing water, plankton, and small fish to pass through. The shark then closes its mouth and uses the small teeth and specialized filtering pads in its throat to trap the food. The water is then expelled, leaving the whale shark with its meal.
Unlike some species of sharks that have large, sharp teeth used for catching and consuming prey, the whale shark’s teeth are more adapted for its passive feeding strategy. They may not be impressive in size, but they are perfectly suited to the whale shark’s unique lifestyle.
Fascinating Facts About Whale Shark Teeth
-
Size and Shape: Whale shark teeth are extremely small, conical, and pointed. They measure only a few millimeters in length.
-
Number: A whale shark has several rows of teeth that cover its entire mouth. They are not as large or sharp as the teeth of predatory sharks.
-
Feeding Mechanism: Despite having teeth, whale sharks rely on their filter feeding method, which involves passing water through their mouths and gills while trapping food particles.
-
Dermal Denticles: These tooth-like structures cover the whale shark’s body, providing protection and reducing drag while swimming.

Frequently Asked Questions (FAQs)
1. Do whale sharks have teeth on their eyes?
No, whale sharks do not have teeth on their eyes. They have dermal denticles around their body, including the area near their eyes, but these are not teeth. Dermal denticles are small, tooth-like structures that help with streamlining and protecting the shark’s skin.
2. How do whale sharks use their teeth?
Whale sharks use their small, conical teeth to help trap plankton and small fish while filter feeding. Their teeth are not used for predation but rather assist in trapping food particles that flow into their mouths while swimming.
3. Are whale shark teeth sharp like other sharks?
No, whale shark teeth are not sharp like those of other predatory sharks. They are small, conical, and used for filtering rather than catching and tearing prey. Their feeding strategy is passive, relying on filter feeding rather than active hunting.
4. What are dermal denticles?
Dermal denticles are small, tooth-like structures covering the whale shark’s skin. These denticles help reduce drag while swimming and offer protection from environmental threats. They are different from teeth as they are embedded in the skin and not used for feeding.
5. Why do whale sharks have so many teeth?
Whale sharks have numerous tiny teeth to assist in their filter-feeding process. The teeth help trap plankton and small fish as the whale shark filters large volumes of water for food. Their teeth are not used for predation, but rather to help capture and retain small organisms in their mouths.
Conclusion: A Fascinating Creature with a Unique Feeding Mechanism
In conclusion, while whale sharks do not have teeth on their eyes, their unique anatomy, including the presence of dermal denticles, plays a significant role in their survival. These gentle giants use their teeth primarily for filtering food, a crucial aspect of their feeding behavior. Understanding the role of whale shark teeth and their feeding habits enhances our appreciation of these remarkable creatures.
