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.

What unusual behavior of Bottlenose Dolphins initially puzzled scientists?

• Jumping out of the water

• Brushing against corals and sponges

• Swimming in circles

• Diving to great depths

Which specific species of underwater invertebrates do dolphins prefer?

• Jellyfish and sea urchins

• Seaweed and kelp

• Sea anemones and starfish

• Gorgonian corals, leather corals, and a specific type of sponge

What did scientists suspect about the secretions from corals and sponges?

• They were a food source

• They were toxic to dolphins

• They were used for navigation

• They had antibacterial properties

What was the main focus of the 2022 study on dolphin behavior?

• Dolphin social structures

• Migration routes of dolphins

• Chemical composition of coral secretions

• Dolphin communication patterns

What is one possible reason dolphins engage in this behavior?

• To self-medicate and protect their skin

• To mark their territory

• To attract mates

• To play with other dolphins
