The study found that a left-trunker has more wrinkles and longer whiskers on the left side of its trunk due to frequent use, which affects wear.
Dr. Michael Brecht highlights that the trunk's wrinkle patterns are partly use-dependent, indicating a connection between trunk preference and physical adaptation.
The research presented evidence that Asian elephants have far more wrinkles than African elephants, suggesting these adaptations can enhance trunk flexibility during use.
This comprehensive study on trunk wrinkles provides insights into the flexibility of elephant trunks and the anatomical differences between Asian and African species.
