Dolphins possess remarkably smooth skin, often described as having a texture similar to kamaboko (a type of Japanese fish cake). This unique smoothness is due to their skin renewing approximately every 2 to 3 hours. In contrast, human skin undergoes a turnover cycle roughly every 28 days. This rapid regeneration in dolphins plays a crucial role in maintaining their health and comfort in aquatic environments.

Factors Contributing to Rapid Skin Renewal:

• Protection Against Microorganisms: The ocean is home to various bacteria and parasites. To defend against these potential threats, dolphins continuously produce new skin cells, ensuring their skin remains clean and healthy, thereby reducing the risk of infections.
• Enhanced Hydrodynamics: A smooth skin surface minimizes water resistance, allowing dolphins to swim efficiently. By frequently shedding old skin cells, they maintain this sleek surface, facilitating swift and agile movements in water.

Behavioral Observations:

During wild dolphin watching tours with Dolphins & You, dolphins are sometimes observed rubbing their bodies against rocks, the seafloor, or even other dolphins. This behavior is believed to aid in removing old skin cells and debris, promoting the emergence of new skin. Additionally, such actions may help eliminate parasites and bacteria, further contributing to skin health. This behavior also fosters social bonds among dolphins, serving both health and social purposes.

Conclusion:

The rapid skin renewal process in dolphins, occurring every 2 to 3 hours, is a remarkable adaptation that supports their aquatic lifestyle. It aids in infection prevention and ensures smooth movement through water. For humans, the perpetually smooth skin of dolphins is indeed enviable.
