Dolphins 'Smile' During Play to Enhance Communication
Dolphins Exhibit Unique Communication Through Smiles
In a recent study published in iScience, researchers discovered that dolphins display an open-mouthed expression akin to a ‘smile’ while engaging in play with each other. This behavior was observed in both bottlenose dolphins in Italy and France. The study noted that dolphins 'smiled' when their playmates were in sight, suggesting a form of communication that helps prevent conflicts during play.
Understanding Dolphin Playfulness and Communication
While dolphins are renowned for their playful nature, this study highlights the importance of their expressions in social interactions. Heather Hill, a dolphin-communication expert, emphasizes caution in labeling these expressions as true smiles, indicating that open-mouthed displays serve various communicative purposes.
- Dolphins exhibited the 'smile' 92% of the time during play.
- This behavior is absent during aggressive interactions or solitary swimming.
- Future research may explore vocal communications accompanying play.
This remarkable insight into dolphin behavior enriches our understanding of animal communication and underscores the similarities in play behaviors across species.
