The scales on the back of the Whale Shark are dark brown or black, while those on the belly are white with black spots. These colorations help the shark camouflage itself in the water.
Whale shark scale regeneration and growth process
Prior to this study, only one other record of dorsal fin regeneration had been documented in a whale shark. This provides the first evidence of dorsal fin regeneration in a silky shark and contributes to the limited studies of wound healing rates in sharks.
Are whale shark scales harmful to humans?
The whale shark poses no threat to humans due to its unique biological design and feeding strategy. Unlike predatory sharks, the whale shark is a filter feeder, meaning its diet consists of tiny organisms.
What do whale shark scales look like and how are they structured?
While they lack nictitating membranes (or "3rd eyelids"), whale sharks are the only species with denticles (scales) on their eyeballs, providing extra protection against abrasion. Whale sharks do have scales, but they’re different from regular fish scales. The scales of a whale shark are like tiny teeth called dermal denticles. They offer protection and faster swimming for the whale shark. Whale sharks have grayish, brownish, or bluish backs with a white underbelly.
Comparing whale shark scales to other marine animal scales
How whale shark scales help with swimming efficiency
These scales or dermal denticles contain ridges that reduce turbulence created by the swimming of the shark making their movement quieter and more efficient.
Whale shark scale patterns and their scientific significance
Beyond its role in survival, the whale shark’s spot pattern serves an important function for scientists. The unique arrangement of spots on an individual shark’s body, particularly the area directly behind the gills, remains constant throughout its life.
