Why Taking Turns Is Good for Dolphin Skin

Bottlenose Dolphins exhibit a unique behavior of brushing against corals and sponges, which may serve as a skin care routine. Scientists observed this behavior and hypothesized that dolphins use secretions from specific corals and sponges for their antibacterial properties. A 2022 study analyzed these secretions, finding some compounds to be antibacterial. While the exact reason for this behavior remains unclear, it may be a form of self-medication or simply a soothing activity. Dolphins teach this behavior to their young, but further research is needed to fully understand the implications and effects on fragile reef ecosystems.
